Description

Technical Field

[0001] The present invention relates to the technical field of tunnel intelligent blasting hole position design, and in particular to a hole position determination method and device based on charge section resistance line uniformity. Background Art

[0002] In tunnel blasting projects, blasting effectiveness is directly dependent on the design of the blasthole positions. This invention aims to accurately calculate the positions of the blasthole ends based on the uniformity of the charge resistance line. Leveraging the precise hole-finding and positioning capabilities of a computerized drilling rig, this technology accurately replicates design requirements in actual projects, thereby improving blasting effectiveness.

[0003] In the past, limitations of drilling equipment and technology led to unavoidable large discrepancies between the designed and actual hole locations in underground engineering blasting designs. Furthermore, due to limitations in design methods and software, the resistance lines of different charge sections varied significantly, resulting in a high degree of randomness in the blasting tasks assigned to each hole. This led to low blasting efficiency and reduced blasting quality. To ensure smooth blasting and compensate for these adverse effects, increasing the number of holes and charge sizes was often employed, but this resulted in significant consumption and waste of blasting equipment.

Any embodiment or design described as an "exemplary" in the present invention should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of the word "exemplary" is intended to present concepts in a concrete manner. Furthermore, in the embodiments of the present invention, "and / or" can mean both or either of the two.

[0027] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0028] Figure 1 This is a flow chart of a method for determining hole positions based on the uniformity of the charge section resistance line according to an embodiment of the present invention. Figure 1 As shown, the method specifically includes the following steps:

[0029] Step S102: Based on the value range of the auxiliary hole bottom resistance line, determine the preset value of the hole bottom resistance line, the number of auxiliary hole rows and the hole opening position of each row of auxiliary holes.

[0030] Step S104, based on the first calculated error between the bottom resistance line of the peripheral holes and the first target value, iteratively correct the preset value of the bottom resistance line and the bottom positions of each row of auxiliary holes calculated based on the preset value of the bottom resistance line until the first calculated error does not exceed the preset error value.

[0031] Step S106: Based on the number of auxiliary hole rows and the preset charge section length, the charge column position, charge column resistance line value and charge column resistance line average value of each row of auxiliary holes are determined.

[0032] Step S108, using the mean value of the charge column resistance line as the initial value of the charge column resistance line preset value, iteratively calculate the charge column position and the hole mouth position of each row of auxiliary holes.

[0033] Step S110, repeat the iterative calculation until the bottom resistance lines and charge column resistance lines of all auxiliary holes are equal, and obtain the auxiliary hole position results.

[0034] Specifically, the auxiliary hole position result includes the auxiliary hole opening position and the auxiliary hole bottom position.

[0035] An embodiment of the present invention provides a hole position determination method based on the uniformity of the resistance line of the charging section. The resistance line of the charging section of each row of blast holes is updated based on the uniformity of the resistance line of the entire charging section and the calculation error. The calculation converges quickly and the final position of the hole mouth and the hole bottom of each row of auxiliary holes can be obtained efficiently. On the basis of ensuring the control requirements of the resistance line error of the charging section of the surrounding holes, the rationality of the blasting design is improved and the blasting effect is enhanced.

[0036] Specifically, step S102 further includes the following steps:

[0037] Step S1021, determining the value range of the auxiliary hole bottom resistance line based on the geological conditions of the roadway to be blasted, blasting test results or historical engineering experience;

[0038] Step S1022: determining a preset value of the hole bottom resistance line based on the value range of the auxiliary hole bottom resistance line; for example, any value within the value range of the auxiliary hole bottom resistance line is determined as the preset value of the hole bottom resistance line;

[0039] Step S1023, rounding off the ratio of the distance from the cutout hole to the surrounding holes in the hole bottom section to the upper limit of the value range of the auxiliary hole bottom resistance line to obtain the number of auxiliary hole rows;

[0040] Step S1024: dividing the distance from the cutout hole to the surrounding holes in the hole section according to a preset division rule to obtain a plurality of division intervals;

[0041] Step S1025 : determining the orifice positions of each row of auxiliary holes based on the multiple divided intervals.

[0042] Specifically, step S104 further includes the following steps:

[0043] Step S1041, calculating a preset value of the hole bottom resistance line based on the ratio of the distance between the cut hole and the surrounding holes in the hole bottom section to the number of auxiliary hole rows;

[0044] Step S1042 , starting from the auxiliary hole closest to the cut hole, the hole bottom positions of each row of auxiliary holes are calculated according to the preset value of the hole bottom resistance line.

[0045] Step S1043, determining a first calculated error between the bottom resistance line of the peripheral holes and a first target value based on the bottom positions of the auxiliary holes in each row;

[0046] Specifically, the calculation formula of the first calculation error includes:

[0047]

[0048] Among them, E P is the first calculated error between the peripheral hole bottom resistance line and the first target value, W PCis the resistance line of the bottom of the surrounding holes, W PC0 is the first target value.

[0049] Step S1044, establishing a function for determining the increment of the hole bottom resistance line based on the first calculation error;

[0050] Among them, the functions of the hole bottom resistance line increment include:

[0051]

[0052] ΔW P is the resistance line increment of the auxiliary hole bottom, λ is the learning rate, g1(λ) is the function related to the learning rate in the iterative calculation process, E P is the first calculation error, f1(E P ) is the distribution function with respect to the first calculation error.

[0053] Step S1045: iteratively correct the preset value of the hole bottom resistance line and the hole bottom positions of each row of auxiliary holes based on the function of the hole bottom resistance line increment. Specifically, after each round of iterative correction, the hole bottom position is updated.

[0054] In an optional implementation provided by an embodiment of the present invention, the first target value is a preset value of the bottom resistance line of the peripheral hole, which is a preset value.

[0055] For example, if the first target value (the preset value of the bottom resistance line of the peripheral holes) is 800 mm, after calculating the bottom positions of all auxiliary holes, the bottom resistance line of the peripheral holes is determined to be 700 mm, then the first calculation error is 800-700=100 mm.

[0056] This shows that the preset values ​​of the bottom resistance lines of the aforementioned rows of auxiliary holes are too large, resulting in only 700 mm of space left for the bottom resistance lines of the surrounding holes, a shortfall of 100 mm.

[0057] At this time, if there are 5 rows of auxiliary holes, and the preset value of the bottom resistance line of each row of auxiliary holes is 1000mm, the 100mm error can be distributed to the 5 rows of auxiliary hole heads. In this way, the preset value of the bottom resistance line of each row of auxiliary holes is adjusted to 1000-100 / 5=980. After iteration, the calculation error in the next round will be reduced accordingly and will eventually converge.

[0058] Optionally, the first calculated error and the preset value of the hole bottom resistance line can be an arbitrarily set functional relationship, as long as the functional relationship can ensure that the calculated error can converge.

[0059] Specifically, step S106 further includes the following steps:

[0060] Step S1061, determining the charge column head position of each row of auxiliary holes based on the preset charge section length;

[0061] Step S1062, calculating the charge column resistance line value of each row of auxiliary holes;

[0062] Specifically, the charge column resistance line value is equal to the shortest distance from the charge column to the axis of the front row of blastholes.

[0063] Step S1063: Calculate the mean value of the charge column resistance line based on the charge column resistance line value of each row of auxiliary holes. Specifically, the calculation formula is:

[0064]

[0065] Among them, W Em is the mean value of the auxiliary hole charge column resistance line, K is the number of auxiliary hole rows, k is the auxiliary hole row number, W Ek The resistance line value of the charge column of the kth row of auxiliary holes.

[0066] Specifically, step S108 further includes the following steps:

[0067] Step S1081, taking the mean value of the charge column resistance line as the initial value of the preset value of the charge column resistance line;

[0068] Step S1082, starting from the auxiliary hole closest to the cut hole, the hole opening positions of each row of auxiliary holes are calculated according to the preset value of the charge column resistance line;

[0069] Step S1083, calculate the second calculated error between the peripheral hole charge column resistance line and the second target value; the specific calculation formula is as follows:

[0070]

[0071] Among them, E E is the second calculated error between the peripheral hole charge column resistance line and the second target value, W EC W is the resistance line of the peripheral hole charge column. EC0 is the corresponding second target value.

[0072] Step S1084: Establish a function for determining the charge column resistance line increment based on the second calculation error. The specific calculation formula is as follows:

[0073]

[0074] Where ΔW E is the resistance line increment of the auxiliary hole charge column, λ is the learning rate, g2(λ) is the function related to the learning rate in the iterative calculation process, E Eis the second calculated error between the peripheral hole charge column resistance line and the second target value, f2(E P ) is the second calculation error E E The allocation function.

[0075] Step S1085: Iteratively calculate the charge column position and the hole opening position of each row of auxiliary holes based on the function of the charge column resistance line increment. Specifically, after each iterative calculation, the charge column position and the hole opening position are updated.

[0076] In step S110, since updating the charge column position and the hole mouth position will cause changes in the blasthole angle and the hole bottom resistance line, and updating the hole bottom position will also cause changes in the blasthole angle and the charge column head resistance line, repeated calculations are required.

[0077] During repeated calculations, if the calculation error still fails to meet the requirements, the function that determines the resistance line increment based on the error and the learning rate can be adjusted. Matlab programming software can be used to write a function to determine the value of the learning rate during each round of calculation.

[0078] The present invention also provides an application example of hole position determination, referring to Figure 2 The figure shows an application example of hole position design based on the uniformity of the resistance line of the charging section.
