Description

Tunnel blasting pattern automated design system and method for selecting dominant security objects using a critical object index based on integrated geometric information AND METHOD FOR THE SAME}

The present invention relates to the automation design of tunnel blasting patterns. More specifically, when designing the automation of tunnel blasting patterns, the Critical Object Index (COI) is used to select the dominant safety facility, which is the main security object at the blasting point. It relates to a tunnel blasting pattern automation design system and method that calculates and creates tunnel automation design results and selects dominant security objects using a critical object index based on integrated geometric information.

In general, blasting using gunpowder as a method of excavating rock during tunnel construction is more economical than other methods and is still widely used to this day. Blasting work that excavates rock using the explosive power of gunpowder must not only maximize blasting efficiency from the design stage, but also consider tunnel stability and blasting pollution such as blasting vibration and noise.

As such, the blasting vibration generated by blasting is a very important issue, and the level of vibration that will occur as a result of the blasting work must be predicted before the blasting work is performed. For this purpose, constants used in the blast vibration estimation equation are determined through test blasting and reflected in the blast design, but this requires a lot of time and cost.

In particular, when designing a tunnel, the blasting design cannot be planned in detail due to scheduling and cost issues, and the route is designed with only a few conditions in mind. As a result, over-exaggerated or over-designed blasting patterns are being applied to the field, and there are problems with environmental damage caused by blasting vibration and construction costs being overestimated.

Meanwhile, Figure 1A is a diagram showing a typical blasting design procedure, and Figure 1B is a diagram illustrating a blasting pattern.

As shown in FIG. 1A, the tunnel blasting design method used so far has been performed by calculating manpower and determining the blasting pattern at each point, taking into account the conditions at each point along the route.

However, this existing tunnel blasting design requires a lot of time to determine major obstacles, calculate the separation distance, and calculate the blasting charge amount, and if the conditions of the route change, there is a problem in that the tunnel blasting design must be performed again through the same steps.

In addition, since adjacent obstacles are considered first when calculating major obstacles, there is a problem that obstacles that are far apart but have low allowable vibration standards are omitted in the blasting design.

Meanwhile, FIG. 2A is a diagram for explaining the blasting vibration estimation equation, and FIG. 2B is a diagram illustrating the square root converted distance.

As shown in FIG. 2A, the blast vibration estimation equation is a function of the distance and the maximum charge per delay. For example, the blast vibration estimation equation can be given as in Equation 1 below.

[Equation 1]

here, represents the ground vibration speed [cm/sec], represents the blasting constant (or location constant), represents the security distance [m], which is the distance between the width and the main point, represents the maximum charge per delay [kg], represents the attenuation index (attenuation constant), represents the load index.

Specifically, from the relationship between distance and charge amount per delay, is called Scaled Distance (SD), and is the load index. If the value is 1/2, it is called Square Root Scaled Distance, and if it is 1/3, it is called Cube Root Scaled Distance.

In general, it is known that the cubic root conversion distance is appropriate for short distances, and the square root conversion distance is appropriate for long distances.

For example, as shown in Figure 2b, the square root converted distance, that is, the security distance is the value divided by the square root of the charge amount. It is a method of expressing the maximum particle speed as a function of , and is more commonly used than the cubic root converted distance.

This square root conversion distance is based on the charge being distributed in a long rod shape, so if the density per unit length of the blast hole is constant, the diameter of the blast hole is proportional to the square root of the charge amount. thus The ratio of is approximately two lengths, that is, the security distance, which is the distance between the blast point and the center of the receiver. and It represents the ratio of the blast hole radius proportional to .

also, and is a value that represents the influence of factors that cannot be quantitatively evaluated. (Blasting constant) represents an integer representing the geometric shape of the blasting site and nearby structures, the geological characteristics and mechanical characteristics of the target rock, (Attenuation constant) is a constant depending on the blasting conditions and refers to an index representing the type of explosive, charge amount, detonation method, discoloration state, number of free surfaces, blasting type, and the distance between the blast source and measuring point.

In addition, as shown in Figure 2a, the separation distance [m], which is the distance between the width and the starting point, can be expressed as the following equation 2, and the maximum charge amount per delay [kg] is can be expressed as Equation 3 below:

[Equation 2]

[Equation 3]

Meanwhile, Figure 3a is a diagram showing designing a blasting pattern through cross-sectional examination of each security object according to the prior art, and Figure 3b is a diagram showing calculating the vibration speed and vibration level when designing the blasting pattern.

When designing a tunnel blasting pattern according to conventional technology, as shown in Figure 3a, the blasting pattern is designed by human labor through a cross-sectional review of each security object.

Specifically, safety facilities refer to equipment, facilities, etc. that require protection from hazards in handling explosives, and include Type 1 security facilities, Type 2 security facilities, Type 3 security facilities, and Type 4 security facilities. It can be divided into: For example, Type 1 security objects include buildings designated as national treasures, houses in urban areas, schools, childcare centers, hospitals, temples, churches, and stadiums. Additionally, type 2 security objects refer to houses and parks in villages.

In addition, Type 3 security items include houses, railways, tracks, ship routes or moorings, oil storage facilities, and high-pressure gas production/storage facilities (including charging stations) that do not belong to Type 1 or Type 2 security items. ), power plants, substations, and factories. In addition, Type 4 security objects refer to roads, high-voltage wires, explosives handling stations, and firearms handling stations under each subparagraph of Article 10 of the Road Act.

The tunnel blasting design procedure according to the conventional technology first selects a support pattern that reflects the results of the ground investigation, as shown in Figure 3a, then determines the charge amount (explosive amount) per delay, and then determines the amount of charge per security object. Calculate the vibration speed.

after. As shown in Figure 3b, if the calculated vibration speed is greater than the allowable value, it is changed to controlled blasting that adjusts the excavation length and charge amount. However, in the case of tunnel blasting design according to conventional technology, there is a problem of inefficiency because the blasting pattern is designed by human labor through a cross-sectional review of each security object.

Meanwhile, in recent tunnel blasting work, various field conditions required for tunnel blasting, such as site rock conditions, gunpowder or detonator, etc., are input, and based on these, a tunnel blasting pattern diagram and detonator/detonator are created. It has been developed to automatically output usage details, making it possible to form blasting pattern diagrams that objectively, quickly and accurately reflect various on-site situations.

In addition, it was possible to minimize blasting vibration by predicting the vibration value due to blasting during blasting work and modifying the blasting pattern based on this.

In addition, by manually inputting additional field conditions that change during blasting work and modifying the blasting pattern, the predetermined blasting pattern can be quickly and accurately modified according to changing field conditions.

In other words, based on the standard blasting pattern determined by theory, the problems of inefficiency and inaccuracy caused by the fact that the standard blasting pattern is mostly modified and applied in the field mainly relying on personal empirical factors can be solved. By accurately identifying the correction factors caused by variable field conditions, a modified blasting pattern that can be practically applied in the field can be automatically designed.

Meanwhile, Figure 4 is a diagram illustrating the need to calculate the dominant security object, which is the main security object at each point, when designing tunnel blasting according to conventional technology.

As shown in Figure 4, when designing tunnel blasting according to conventional technology, it is necessary to calculate the dominant security object, which is the main security object at each point.

Here, the controlling security object must take into account both the distance between the blasting point and the security object and the allowable blasting vibration standards of the security object. For example, the distance from the blasting point to the adjacent security object is L _B > L _C > L _D , and at this time, the distance to the fourth security object (L _D ) is the closest.

delete

However, the calculated charge amount considering the allowable vibration value is W _B < W _C < W _D , so the charge amount (W _B ) up to the second security object is minimum.

Accordingly, the blasting location is governed by the second security object, and the charge quantity must be calculated to reflect this. In other words, the second security object should be selected as the dominant security object, and the tunnel blast design should be designed taking this into account.

Meanwhile, as a prior art related to the automatic design of tunnel blasting patterns, Republic of Korea Patent Publication No. 2000-61481 is an invention entitled "A recording medium recording a method for automatically designing a tunnel blasting pattern and a program providing a tunnel blasting pattern diagram." This is disclosed, and will be described with reference to FIG. 5.

Figure 5 is an operation flowchart showing an automatic tunnel blasting design method according to the prior art.

Referring to FIG. 5, the automatic design method for tunnel blasting according to the prior art first determines the cross-sectional shape of the tunnel where blasting will be performed, and determines the tunnel cross-section by inputting variables corresponding to the selected tunnel cross-section (S11 ).

Next, select the core type, enter the information of the tunnel site into the tunnel site database, enter the information of the gunpowder to be used into the gunpowder database, and enter and store the information of the detonator to be used in the detonator database (S12 ).

Next, in the proposed equation selected for tunnel blasting, each data input in the data input/storage step is calculated as input parameters, and output parameters directly used in designing the tunnel blasting pattern are obtained, namely, rock coefficient, space gap, and resistance line. Calculate the length and type and number of explosives used (S13).

Next, based on the determined design parameters, the location of the blast hole on the tunnel cross-section is determined, the usage details of the gunpowder are determined, and the usage details of the detonator are determined according to the time difference and amplitude sequence appropriate for each blast hole (S14).

Next, the vibration value due to blasting is predicted based on the determined blasting pattern (S15).

Next, check whether the predicted blasting vibration value exceeds the standard allowable vibration value (S16).

Next, if the predicted blasting vibration value exceeds the standard allowable vibration value, the location of the blasting hole on the tunnel cross-section is determined, the usage details of gunpowder and detonator are determined, and the amount of charge per delay is determined by detonating time difference appropriate for each blasting hole. By correcting, the vibration of the blasting pattern is corrected so that the vibration caused by the blasting pattern is within the allowable vibration value (S17).

Next, if the predicted blasting vibration value does not exceed the standard allowable vibration value, a safety blasting pattern diagram is created (S18).

At this time, in order to allow the user to additionally appropriately reflect the changing field situation based on the blasting pattern determined through the above steps, the designed blasting pattern can be manually changed and entered.

In other words, in the case of the automatic tunnel blasting design method according to the conventional technology, information about the cross section of the tunnel for which the blasting pattern will be created is input, and the tunnel site database (rock strength, gunpowder used, etc.) is input.

Afterwards, in order to calculate the design parameters required for the blasting pattern (rock coefficient, bore spacing, charge amount, etc.), a blasting pattern diagram is created by calculating the parameters using the Swedish formula, and then an analysis step is performed to predict the blasting vibration. Through this, various field conditions required for tunnel blasting can be used as input data to automatically output tunnel blasting pattern diagrams and detonator/gunpowder usage details.

According to the automatic design method for tunnel blasting according to the conventional technology, the standard blasting pattern diagram is mostly modified and applied in the field mainly depending on personal experiential factors, based on the standard blasting pattern diagram determined by existing theory. Problems of efficiency and inaccuracy have been solved, and by accurately identifying correction factors caused by variable field conditions, a modified blasting pattern that can be practically applied in the field can be automatically designed.

However, in the case of the automatic tunnel blasting design method according to the conventional technology, there is a limitation in that the optimal tunnel blasting pattern cannot be designed because it does not take into account the dominant security object according to the blasting location.

In the end, as mentioned above, the typical existing tunnel blasting design selects the tunnel support pattern through the results of ground investigation, determines the amount of explosives, reviews the vibration effect affecting surrounding security objects, and then adjusts the amount of explosives. This is done by designing the blasting pattern.

In particular, when designing tunnel blasting, the distance between the blasting point and the security object and the allowable blasting vibration standards of the security object must all be considered. In particular, it takes a lot of manpower and time to investigate adjacent security objects depending on the tunnel alignment. There is a problem.

[Tunnel blasting pattern automated design system (100) that selects dominant security objects using a critical object index based on integrated geometric information]

Figure 6 illustrates the concept of automating tunnel blasting design based on digital field geometric information in a tunnel blasting pattern automation design system that selects dominant security objects using a critical object index based on integrated geometric information according to an embodiment of the present invention. This is a drawing for this purpose.

First, the tunnel blasting pattern automation design system that selects dominant security objects using a critical object index based on integrated geometric information according to an embodiment of the present invention automates tunnel blasting pattern design based on 3D digitized on-site geometric information. It is for this purpose.

As shown in Figure 6, in the case of the tunnel blasting pattern automation design system according to an embodiment of the present invention, for example, tunnel blasting design is automated based on the geometric information of the field digitized according to the Dynamo program provided by Autodesk. It can be done, but it is not limited to this.

Specifically, in the case of the Dynamo program used in the tunnel blasting pattern automated design system according to an embodiment of the present invention, as shown in FIG. 6, linear information of the tunnel construction route can be easily extracted and the tunnel construction route can be Accordingly, the coordinates of continuous blasting points can be extracted.

In addition, objects can be created in the coordinates of security objects or security object information can be extracted, and extraction of the shortest distance between objects is included as a built-in function.

In addition, it provides tunnel design information for each location of the tunnel construction route. For example, information on the support pattern along the tunnel construction route can be input, and the charge amount can be arranged and calculated according to the pattern information.

Accordingly, the tunnel blasting pattern automated design system according to an embodiment of the present invention selects a dominant security object using a critical object index based on integrated geometric information, and also constructs a tunnel based on 3D digitized on-site geometric information. Blasting design can be automated.

Specifically, the coordinates of continuous points along the route are extracted through linear information of the tunnel construction route, and information on security objects spaced a certain distance around the tunnel construction route is extracted through geographic information provided by a geographic information system (GIS: 300). are collected respectively, the coordinates of security objects are generated through this, and the Critical Object Index (COI) is calculated to calculate the relationship with surrounding security objects at all points along the tunnel construction route.

In other words, the ratio of the distance between the blasting point and the security object and the distance that satisfies the permissible vibration standards of the security object is calculated.

In particular, the tunnel blasting pattern design results can be created by extracting the minimum critical object index (COI) calculated as the dominant security object at the blast point.

Meanwhile, Figure 7 shows the relationship between each security object at all points along the tunnel construction route in the tunnel blasting pattern automated design system that selects the dominant security object using a critical object index based on integrated geometric information according to an embodiment of the present invention. This is a diagram to explain calculating the critical object index (COI) to standardize.

The tunnel blasting pattern automated design system according to an embodiment of the present invention is a method for standardizing the relationship with each security object at all points along the tunnel construction route, and as shown in FIG. 7, the critical object index (COI) is used. Calculate

Here, the critical object index (COI) refers to an index for selecting the dominant security object at the blasting point for tunnel blasting design, and the security object with the minimum critical object index (COI) dominates the blasting point. Selected as a security object.

Specifically, the critical object index (COI) is the distance between the blasting point and the security object ( ) and the distance that satisfies the allowable vibration standards for the security object ( ) is given as a ratio.

[Equation 4]

At this time, Can be expressed as Equation 5 below:

[Equation 5]

here, represents the allowable vibration value, represents the blast constant, represents the maximum charge per delay [kg], represents the attenuation index (attenuation constant), represents the load index. At this time, Assuming that is 1kg, is given as in Equation 6 below.

[Equation 6]

For example, as shown in Figure 7, the security object with the minimum critical object index (COI) at point A becomes the dominant security object.

Specifically, when the allowable vibration speed of the first security object is 0.2cm/sec and the separation distance is 90m, COI is calculated as 1.2, the allowable vibration speed of the second security item is 0.1cm/sec, and the separation distance is When 80.5m, the COI is calculated as 0.7, the allowable vibration speed of the 3rd security object is 0.3cm/sec, and when the separation distance is 58m, the COI is calculated as 1.0, and the allowable vibration speed of the 4th security object is 1cm/sec. And if the COI is calculated as 0.8 when the separation distance is 22m, the second security object with a COI of 0.7 can be selected as the dominant security object even if the separation distance is farther than the third security object and the third security object. .

Meanwhile, Figure 8 is a configuration diagram of a tunnel blasting pattern automated design system that selects a dominant security object using a critical object index based on integrated geometric information according to an embodiment of the present invention.

Referring to FIG. 8, the tunnel blasting pattern automation design system 100, which selects a dominant security object using a critical object index based on integrated geometric information according to an embodiment of the present invention, includes a data collection and processing module 110, It is composed of a controlling security object setting module (120), a design information processing module for each tunnel location (130), an automated design result writing module (140), and an automated design result output module (150).

The data collection and processing module 110 extracts the tunnel linear information of the tunnel construction route from the tunnel design DB 200, divides it linearly, and uses the geographical information collected from the geographic information system (GIS) 300 to construct the tunnel construction route. Collect each security object information. Here, the data collection and processing module 110 may include a tunnel linear information extraction unit 111, a tunnel construction route linear division unit 112, and a security object information collection unit 113.

Specifically, the tunnel linear information extraction unit 111 of the data collection and processing module 110 extracts tunnel linear information of the tunnel construction route from the tunnel design DB 200. In addition, the tunnel construction route linear division unit 112 of the data collection and processing module 110 linearly divides the tunnel construction route according to the extracted tunnel linear information.

In addition, the security object information collection unit 113 of the data collection and processing module 110 collects security object information on each tunnel construction route using geographic information collected from the geographic information system 300.

The controlling security object setting module 120 estimates the blasting vibration according to the test blasting results or the blasting vibration estimation formula according to the literature proposal, and calculates the critical object index (COI) from the critical object index (COI) calculation formula corresponding to the estimated blasting vibration. COI) is calculated, and the dominant security object at each linear point of the tunnel construction route is selected according to the calculated critical object index (COI).

Here, the dominant security object setting module 120 may include a blast vibration estimation unit 121, a critical object index calculation unit 122, and a dominant security object selection unit 123.

Specifically, the blasting vibration estimation unit 121 of the dominant security object setting module 120 uses the security object information collected by the security object information collection unit 113 as a test blasting result or a blasting vibration estimation formula according to a formula proposed in the literature. The blasting vibration is estimated from .

In addition, the critical object index calculation unit 122 of the dominant security object setting module 120 calculates the critical object index (COI) from the critical object index (COI) calculation formula corresponding to the estimated blasting vibration to select the dominant security object. Calculate . In addition, the dominant security object selection unit 123 of the dominant security object setting module 120 selects a dominant security object for each linear point of the tunnel construction route according to the calculated critical object index (COI). Accordingly, the investigation of security objects adjacent to the linear blasting point of the tunnel construction route can be simplified.

The design information processing module 130 for each tunnel location processes design information for each tunnel location according to the dominant security object selected in the dominant security object setting module 120.

The automated design result creation module 140 creates tunnel blasting automation design results from the design information for each selected tunnel location.

The automated design result output module 150 visualizes and outputs the tunnel blasting automated design result in 3D.

In other words, the coordinates of continuous points along the route are extracted through the linear information of the tunnel, and information on buildings at a certain distance around the route can be known through GIS information, so an object is created in the coordinates of the security object through this.

[A tunnel blasting pattern automation design method that selects dominant security objects using a critical object index based on integrated geometric information]

Figure 13 is an operation flowchart showing a tunnel blasting pattern automation design method for selecting a dominant security object using a critical object index based on integrated geometric information according to an embodiment of the present invention.

Referring to FIG. 13, the tunnel blasting pattern automation design method for selecting a dominant security object using a critical object index based on integrated geometric information according to an embodiment of the present invention is, first, the tunnel construction route is designed to automate tunnel blasting. Tunnel linear information is extracted and linearly divided (S110).

Next, information on security objects on the tunnel construction route, such as location, distance, and allowable vibration standards, is collected using geographic information collected from a geographic information system (GIS) (S120).

Next, the blasting vibration is estimated from the test blasting results or the blasting vibration estimation formula according to the formula proposed in the literature (S130). For example, blasting vibration is estimated according to Equation 1 described above.

Next, in order to select the dominant security object, which is the main security object at the blasting point, the critical object index (COI) is calculated from the COI calculation formula corresponding to the estimated blasting vibration (S140).

Here, the critical object index (COI) is an index for selecting the controlling security object at the blasting point for tunnel blasting design. The critical object index (COI) controls each linear point of the tunnel construction route according to the critical object index (COI). You can select security objects and create tunnel blast automation design results based on design information for each tunnel location.

Specifically, the critical object index (COI) is, as shown in Equation 4 above, the distance (D) between the blasting point and the security object and the allowable vibration of the security object under the condition that the charge quantity (W) is assumed to be 1 kg. It is given as a ratio of the distance (Do) that satisfies the standard, and the security object with the minimum critical object index (COI) can be selected as the dominant security object at the corresponding blast point.

Next, the dominant security object at each linear point of the tunnel construction route is selected according to the calculated critical object index (COI) (S150).

In other words, by calculating the critical object index (COI) and selecting the dominant security object at the blasting point, the investigation of security objects adjacent to the linear blasting point of the tunnel construction route can be simplified.

Next, design information for each tunnel location corresponding to the selected dominant security object, for example, excavation length, charge amount, controlled blasting method, etc., is processed (S160).

Here, the design information for each tunnel location can be calculated by inputting support pattern information according to the tunnel construction route and arranging the charge amount according to the support pattern information.

Next, the tunnel blasting automation design result is prepared according to the design information for each dominant security object and tunnel location (S170).

Next, the tunnel blasting automation design results are visualized in 3D and output (S180). For example, the blasting impact derived as a result of the tunnel blasting automation design can be visualized and output in 3D in the form of a sphere.

Ultimately, according to an embodiment of the present invention, when designing tunnel blasting pattern automation, the optimal tunnel blasting automation design can be derived by calculating the critical object index (COI) and selecting the dominant security object at the blasting point. In addition, the optimal tunnel blasting automation design can be derived. Design information for each security object and tunnel location can be selected to derive automated design results, and the effects of blasting can be visualized and printed in 3D based on 3D digitized geometric information of the site.
