Description

Blasting design system that reflects the situation of the blasting site and its operation method {BLASTING DESIGN SYSTEM REFLECTING THE SITUATION OF THE BLASTING SITE AND OPERATION MATHOD OF THE SAME}

Embodiments of the present invention are a blasting design system that reflects the situation of the blasting site and its operation method. In particular, blasting is designed by reflecting the situation of the blasting site at each stage, and the blasting design is modified based on the work results at each stage. It relates to a blasting design system that can be analyzed and that reflects the situation at the blasting site and its operation method.

Generally, in construction fields such as rock blasting, abandoned building blasting, and open-air blasting, a blasting system that explodes and collapses using explosives is used.

Specifically, the area or object to be blasted is divided into a plurality of sections, and a plurality of blasting holes into which explosives are inserted are drilled for each section. After charging explosives into each of the drilled blast holes, they are connected to a blasting device. By detonating the detonators located in the blast holes, the explosive explodes and the object to be blasted explodes and collapses.

Regarding the operation of such a blasting system, each process has conventionally been performed directly by humans or by machines operated by humans. However, there is a possibility that human errors may occur in this conventional blasting system. In addition, there was a problem in that the blasting results of the blasting system did not satisfy the conditions required by the error (e.g., blasting degree, scale, crushing degree, vibration, noise, etc.).

Additionally, the conventional blasting design system performed blasting design on a virtual plane. However, the blast design system, which performs blast design on a virtual plane, has a problem in that the reliability of result prediction is greatly reduced because it does not reflect actual three-dimensional topographical information.

In addition, in operations such as drilling and charging, differences may occur between the blasting design and the actual work results, and the differences are often large. The conventional blasting design system predicts the blasting results on the premise that each operation is carried out accurately according to the blasting design, so there was a problem in that it could not reflect the actual blasting results. Therefore, when comparing blasting results using blasting prediction data and result data in a conventional blasting design system, there was a problem that meaningful results could not be derived.

The charge design unit 320 may set a unit section according to depth for each of the plurality of blast holes (S321).

The charge design unit 320 can allocate explosives for each unit section (S322). For example, the charge design unit 320 can set the type and specific gravity of explosives for each unit section and set the number/length of the color deck. At this time, the charge design unit 320 can set a deck whose length can change according to the change in the length of the blast hole, in case the length of the blast hole changes.

Figure 9 is a flowchart showing in detail the operation method of the blasting design system 10 according to an embodiment of the present invention. Figure 10 is a diagram showing in detail the initial setting method of the blasting design system according to an embodiment of the present invention. Figure 11 is a diagram showing in detail the initial setting method of the blasting design system according to an embodiment of the present invention.

Hereinafter, with reference to FIGS. 1 to 11, the initial design unit 330 of the present invention designs a preliminary design for a plurality of detonators charged into a plurality of blast holes, and generates a preliminary design (S33). It is explained in detail.

The initial design unit 330 may set a delay time/meter(feet) of apparent burden per apparent resistance line length (S331). For example, the delay time per length of the apparent resistance line in general bench blasting has a value of 10ms/m (hard rock) to 30ms/m (soft rock). If it is too long, it can cause tombstones, explosions, or lumps, and if it is too short, it can cause backfire. Heat of rock may move upward instead of horizontally. The initial design unit 330 according to an embodiment of the present invention can set a delay time per apparent resistance line length to prevent the above problem from occurring.

The initial timing design unit 330 may design the initial timing of each of the detonators loaded into the plurality of blast holes using the contour method based on the delay time per length of the apparent resistance line (S332).

Depending on the embodiment, as shown in FIG. 10, the prime timing design unit 330 may set a prime timing contour. At this time, the initial design unit 330 also sets the delay time (r) per apparent resistance line length corresponding to the contour line.

The delay time (r) per apparent resistance line length can be a negative number when located on the left side of the contour line, and can be a positive number when located on the right side of the contour line. Therefore, the fire time (i.e., detonation time) of the detonators can be divided into positive and negative numbers centered on the contour line.

However, the present invention is not limited to this, and the delay time (r) per apparent resistance line length can be designed in various ways depending on the design method.

The fire time design unit 330 sets the smallest fire time to 0 ms and can calculate the fire time of each blast hole based on this.

For example, the first time design unit 330 can calculate the first time using [Equation 1].

[Equation 1]

FT=CLD*R-|MF|, where FT is the initial time, CLD is the distance from the contour line, R is the delay time per apparent resistance line length, and MF is the smallest initial time.

When setting the contour line, the initial design unit 330 may use a straight line or a box-shaped contour line.

As shown in Figure 11, methods of using straight contour lines include a method of using one contour line, a method of using two or more contour lines whose boundary line is equal to the bisector of the angle between two straight lines, and a method of using two or more contour lines whose boundary line is the same as the bisector of the angle between two straight lines. It can be classified as a method that uses two or more contour lines that are different from the angle bisector.

Depending on the embodiment, the initial design unit 330 evaluates potential blasting performance through the delay time per apparent resistance line length, and continuously checks the delay time per apparent resistance line length through changes consistent with the explosion that occurs throughout blasting. It can be reflected in the design.

Figure 12 is a flowchart showing in detail the operation method of the blast design system 10 according to an embodiment of the present invention. Figure 13 is a flowchart showing in detail the blasting amount calculation method of the blasting design system 10 according to an embodiment of the present invention.

Hereinafter, with reference to FIGS. 1 to 12, the blast prediction unit 400 of the present invention provides blast prediction data for at least one of blast volume, crushability, vibration, and noise using prediction parameters based on the blast design. The step (S40) of generating is described in detail.

The blasting quantity prediction unit 410 may calculate the blasting quantity prediction value based on the blasting design (S41). Referring to FIG. 13, the blasting volume prediction unit 410 may calculate the blasting volume prediction value based on the resistance line (Burden), spacing (Spacing), depth (Length), and subdrilling length (Subdrilling).

Depending on the embodiment, the blasting volume prediction unit 410 may calculate the blasting volume prediction value per blast hole through [Equation 2].

[Equation 2]

VL=SP*BD*(LN-SB), where VL is the predicted blast volume, SP is the space gap, BD is the resistance line, LN is the length, and SB may mean the sub-drill length.

The blasting volume prediction unit 410 can calculate the total blasting volume prediction value by applying the above method to all of the plurality of blast holes.

The present invention is not limited to this, and depending on the embodiment, the blasting volume prediction unit 410 may calculate the blasting volume prediction value using the total area of the blasting area.

The fracture degree prediction unit 420 may calculate a fracture degree prediction value based on regional information and blasting design (S42). For example, the fracture degree prediction unit 420 may calculate a fracture degree prediction value by calculating a Kuz Ram model using the blasting design and already input regional information.

The vibration and noise prediction unit 430 may calculate vibration and noise prediction values based on the blasting design (S43). For example, the vibration noise prediction unit 430 may calculate the vibration and noise prediction values using the blasting vibration equation.

Figure 14 is a flowchart showing in detail the operation method of the blasting design system 10 according to an embodiment of the present invention. Hereinafter, with reference to FIGS. 1 to 14, the step (S60) of the design modification unit 600 modifying the blasting design according to at least one of the drilling result and the charging result will be described in detail.
