Here, the first step is a safe state and indicates a step in which no risk factor occurs during blasting, the second step is an intermediate state, and indicates a step requiring attention of the operator because a risk factor may occur during blasting, and the third step The stage is a dangerous state, and may indicate a stage that requires stopping blasting because a risk factor may occur during blasting.

According to one embodiment of the present invention, the blasting job management device 100 may provide a risk step by considering the work plan information primarily and secondarily considering the expected measurement value when providing the step. For example, the blasting operation management device 100 primarily considers the blasting location, the number of blasting holes, the depth of drilling, the space rate, the charge per hole, the number of blasts, etc. through the work plan information, and secondarily the work plan information. Based on this, expected measurement values including expected noise values and vibration values may be further considered. Accordingly, the blasting job management device 100 may primarily consider the work plan information and secondarily consider the expected measurement value. Here, the blasting job management device 100 may consider the environment around the blasting position and the ground of the blasting position through the blasting position. Perforation is a hole for loading explosives for blasting, and the blasting effect may vary depending on the number, location, direction depth, etc.

Therefore, the blasting job management device 100 primarily considers the work plan information and secondarily considers the expected measured value to generate a warning signal including one of the above-described divided steps and provides it to the worker terminal 200. can do. The worker can check the warning signal through the worker terminal 200 and take action accordingly.

Therefore, the blasting operation management device 100 can establish an integrated solution for blasting operation and management. The blasting work management device 100 compares the estimated measured value with the actual measured value (measured data) measured by the measuring device 20 in real time when a field worker provides a blasting plan and a work log to perform blasting work Accordingly, a vibration estimation value may be calculated using actually measured values (measured data) if necessary. Through this, it is possible to achieve safer and more transparent blasting work with both workability and stability.

According to an embodiment of the present invention, the blasting operation management device 100 measures data measured through a measuring device 20 provided in an adjacent security object (eg, a structure to be protected outside the site) in real time. Upon transmission, corresponding measures and notifications in the field according to the allowable vibration level may be immediately and automatically provided to the worker terminal 200 . Through this, even those who are not familiar with numbers or units can intuitively check at what level the work is being done, and based on the corresponding measures and notifications, change or corrective actions can be taken so that safe blasting work can be done. can

The blasting operation management device 100 may modify the blasting vibration estimation equation according to the current geologic condition in the excavation process by utilizing the cumulative data accumulated through the blasting process.

In the past, in relation to blasting work, test blasting was conducted at the blasting site before starting, and the correlation between the amount of explosives, distance, and vibration speed was calculated and applied. There was the hassle of having to do the test blasting again. The blasting operation management device 100 of the present invention calculates an expected measurement value through a vibration estimation equation using measurement data during actual blasting, and by using the measurement data during actual blasting, the number of samples is greater than that of test blasting. A highly reliable estimation equation can be obtained. In this case, reliability of the vibration estimation equation may gradually increase as the number of samples increases as the blasting operation proceeds.

A general blasting vibration formula for predicting blasting vibration is shown in Equation 1.

In Equation 1 described above, v represents the vibration speed (cm / s), D represents the distance from the blasting position (m), W represents the amount of charge per delay (kg), K represents the blasting vibration constant , b represents the damping index, and n represents the damping index.

In Equation 1, K and n are values representing the influence of factors that cannot be quantitatively evaluated, and may vary depending on geological conditions, blasting methods, and types of explosives. A blast vibration estimation equation suitable for the site can be obtained. By fixing the amount of charge per delay and measuring it at different measurement points, the attenuation index according to the distance can be identified. That is, five or more measuring instruments may be installed at different distances in a straight line to a certain building or facility, and analysis may be performed by obtaining measurement results of 30 or more measurement points.

After organizing the measured results by distance and charge amount, in Equation 1 above, if the variable b is taken as 1/2 and 1/3, and D / W ^b is the scaled distance (SD, Scaled Distance), Equation 2 can be expressed as

When the measured vibration value is displayed on a logarithmic scale graph to perform regression analysis, a linear relationship is established, the K value and the n value are finally determined, and a blast vibration estimation equation suitable for the site is obtained.

Therefore, in the prior art, data of 30 floor points or more through test blasting before this blasting work was statistically processed through Equations 1 and 2, and applied only when starting the site. Accordingly, in the blasting operation management device 100, AI calculates an estimation formula using big data measured for each blasting operation at the site, manages the vibration level, and plans and checks the blasting operation at once, Changes in bedrock and geology or changes in local vibration can be detected in advance and dealt with flexibly.

The PPV value measured by the vibration sensor of the measuring device is used in the blasting vibration estimation equation. Here, the PPV value is the maximum value among the X, Y, and Z directions and represents the vibration speed moving in each of the three directions of the three-dimensional coordinate plane.

The blasting work management device 100 is an AI system, and automatically extracts the amount of charge per delay, the blasting position and the distance of the measurement position in the work plan information transmitted by the worker, receives the measurement data (vibration measurement value), and receives the current rock mass every time And AI automatically calculates a new vibration estimation equation, including the state of vibration change according to geology and location, and uses it in the next operation as a vibration estimation equation with higher reliability, leading to safe blasting work. At this time, the measurement data (vibration measurement value) may be calculated at a desired time and position as the number of accumulations increases (Big Data).

The blasting work management device 100 changes the measured values (measured data) measured through the measuring device 20 so as to comply with the vibration and noise tolerance standards set for each security object set based on the blasting work position 22. According to this, it is possible to ensure that safe blasting work is performed by setting notification and warning levels to the person concerned terminal 200 step by step. At this time, by having the field manager predict vibration in advance according to the amount of gunpowder through the blasting operation management device 100, it is possible to manage the blasting operation so that it does not become unreasonable.

In the past, it was impossible to move the measurement location according to the location of the blasting operation using a fixed measurement device. Even when the blasting work management device 100 uses an integrated solution for blasting work and management even when both fixed and portable measuring devices are used in parallel, real-time measurement information can be shared at all locations, and permitting authorities or Safer and more transparent blasting work can be made possible by providing information to people involved in the field, such as civil petitioners.

Therefore, the blasting operation management device 100 receives the measurement data measured in real time through the measurement device 20 during blasting in a security object within the blasting influence area, and manages vibration and noise. You may not need to check the situation individually. In addition, the blasting operation management device 100 increases the reliability (number of samples) of the vibration estimation formula through the application of regression analysis using big data, and can flexibly cope with changes in rock mass (geological) state.

According to an embodiment of the present invention, the blasting job management device 100 extracts surrounding images after blasting by learning in consideration of images before and after blasting and job plan information taken by installing a separate camera at the blasting site. can Specifically, the blasting operation management device 100 compares an image before blasting (first image) and an image after blasting (second image) through a camera, and based on the changed environmental information after blasting, the image after blasting at the current blasting location. (Second image) can be derived, through which a noise image derived from noise changed after blasting can be generated, and a second image can be derived through the first image based on the noise image.

For example, the blasting job management apparatus 100 may generate a noise image according to the second image by receiving a second image including a noise component of the first image and filtering the second image according to a convolution operation. . At this time, the blasting job management apparatus 100 performs convolution association on the second image using a convolution layer, converts the second image into a feature map representing features related to noise included in the second image, and receives the feature map as an input. A noise image may be generated by reconstructing a feature map related to noise. The blasting operation management device 100 obtains a loss function through a plurality of first images and a plurality of second images in the blasting operation, and performs error back-propagation to set weights for minimizing the error through the loss function. Noise images can be derived better. Therefore, the blasting operation management device 100 may derive a second image after blasting from the first image before blasting through the noise image derived through the above-described process, and through this, by checking the surrounding environment information after blasting in advance, A flexible response may be possible. In addition, the blasting operation management apparatus 100 may express the impact as a feature value representing a tendency as the noise image is derived as a vector (matrix) rather than an image, but is not necessarily limited thereto.
