[0037] The following describes the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0038] The embodiments of the present application are described below in conjunction with the accompanying drawings. Those skilled in the art will appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0039] The terms "first", "second" etc. in the specification of the application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable in appropriate circumstances, and this is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0040] Deep hole loosening blasting is often used in rock stripping and ore recovery projects in large open-pit mines. Deep hole loosening blasting has a high degree of mechanization, fast construction speed, high engineering quality, and relatively concentrated blast piles, which has little damage to bedrock and slopes; it can reduce the amount of explosives used and reduce engineering costs; at the same time, loosening blasting can meet the requirements of high-step mining of large equipment in open-pit mines.

[0041] However, the blasting effect has a direct impact on the subsequent production links, such as the efficiency of mining and transportation equipment, the safety and cost of mining, transportation and drainage production. After the ore and rock are crushed, the unqualified large pieces need to be crushed again, which not only increases the blasting cost, but also affects the loading efficiency. Excessive crushing of useful minerals will affect product quality and reduce economic benefits. The geometric size and shape of the blast pile also have a huge impact on the production links such as mining and transportation.

[0042] At present, with the development of mining engineering, the rock structure of the stripping steps of open-pit coal mines has changed, forming different rock structures, such as soft on top and hard on bottom, hard on top and soft on bottom, soft on top and hard in the middle, etc. The original blasting plan can no longer meet the requirements of the site. There are many large pieces after blasting, large backwash (back flip), high unit consumption of explosives, large secondary crushing, reduced efficiency of mining and loading equipment, and high comprehensive production costs. Therefore, in the mining blasting link, it is particularly important to deeply optimize the blasting parameters and methods such as hole network parameters, hole layout, charging structure, and detonation sequence in combination with the physical and mechanical properties of the step rock mass, rock structure, and the requirements of the subsequent links of mining production.

[0043] See also Figure 1 , Figure 1 The following is a flow chart of a method for controlling deep hole blasting in an open-pit coal mine provided in an embodiment of the present application. Figure 1 As shown, an open-pit coal mine deep hole blasting control method provided in an embodiment of the present application includes steps S10 to S40, and these steps are described in detail below.

[0044] S10, obtaining a first geological feature of the area to be blasted.

[0045] In the embodiment of the present application, the geological characteristics of the open-pit coal mine include, on the one hand, the composition of the rock mass, the type of the rock mass, and the physical and mechanical parameters related to the explosiveness of the rock mass (such as the rock mass bulk density, the rock mass compressive strength, the wave impedance, etc.), and on the other hand, the internal layered structure of the rock mass (such as bedding, foliation, joints), fracture structure (such as weak interlayers, faults, weathering fissures), etc. A corresponding mine geological model can be established according to the engineering geological conditions of the open-pit coal mine.

[0046] The area to be blasted is the location to be blasted in the open-pit coal mine. The geological characteristics of the area to be blasted, that is, the first geological characteristics, are obtained.

[0047] S20, retrieving a blasting record, wherein the blasting record includes a second geological feature of the blasted area and a blasting plan.

[0048] In the embodiment of the present application, before the initial blasting of the open-pit coal mine, it is necessary to investigate and count the current status of mine blasting design, and propose a blasting plan based on the main problems existing in mine blasting, such as root sills, umbrella eaves, and consumption of blasting equipment, in combination with the mine blasting conditions, to improve the blasting effect, reduce the unit consumption of explosives, and improve the economic benefits of the mine.

[0049] During the on-site blasting test, the rock blastability test can be carried out in typical areas of different levels in the open-pit coal mine, that is, the blasting test can be carried out in a suitable location and range within the current blasting operation working surface of the open-pit coal mine. The comparative test is mainly carried out under the same geological conditions by changing parameters such as hole spacing, row spacing, chassis resistance line, over-depth, filling length, delay time, charge structure, and detonation point location. Based on this, blasting plans can be designed for different rock structures and on-site blasting tests can be carried out.

[0050] Based on this, a blasting database management system can be established, which stores blasting records of open-pit coal mines. The blasting records specifically record the geological characteristics (i.e., the second geological characteristics) and blasting plans of the blasted areas. The standard design database can be continuously supplemented and improved, and each design can intelligently match the rock structure of the mining area to accurately determine the blasting plan.

[0051] S30, matching the first geological feature with the second geological feature to determine whether there is a target blasting area in the blasted area with the same geological type as the area to be blasted.

[0052] In an embodiment of the present application, for the second geological feature and blasting plan of the blasted area recorded in the blasting record, the first geological feature is matched with the second geological feature to determine whether there is an area in the blasted area with the same geological type as the area to be blasted (i.e., the target blasting area).

[0053] S40, if there is a target blasting area, taking the blasting plan of the target blasting area as a candidate blasting plan of the area to be blasted, and performing effect evaluation on the candidate blasting plan to generate a blasting plan for the area to be blasted.

[0054] In an embodiment of the present application, if there is a target blasting area with the same geological type as the area to be blasted in the blasted area, the blasting plan of the target blasting area can be used as a candidate blasting plan, and a mine blasting effect evaluation system can be established to evaluate the effects of the candidate blasting plans, and the candidate blasting plan with the best effect can be used as the blasting plan for the area to be blasted.

[0055] See also Figure 2 , Figure 2 A partial flow chart of a method for controlling deep hole blasting in an open-pit coal mine provided in an embodiment of the present application. Figure 2 As shown, an open-pit coal mine deep hole blasting control method provided in an embodiment of the present application, wherein "evaluating the effectiveness of candidate blasting schemes to generate a blasting scheme for the area to be blasted" in step S40 may include steps S401 to S403, and these steps are described in detail below.

[0056] S401, obtaining blasting effect evaluation indicators.

[0057] In the embodiment of the present application, blasting effect evaluation indicators such as large block rate, root sill, umbrella eaves, flying rocks, and unit consumption of explosives can be obtained.

[0058] S402, determining the blasting cost of the candidate blasting scheme based on the blasting effect evaluation index.

[0059] In the embodiment of the present application, the candidate blasting scheme may be quantified under the blasting effect evaluation index to calculate the blasting cost of the candidate blasting scheme.

[0060] S403: The blasting plan with the lowest blasting cost among the candidate blasting plans is used as the blasting plan for the area to be blasted.

[0061] In the embodiment of the present application, after the blasting costs of the candidate blasting plans are obtained, the plan with the lowest blasting cost can be used as the blasting plan for the area to be blasted.

[0062] It should be noted that the blasting plan includes blasting parameters such as explosive consumption, hole network parameters, charging structure, delay interval between holes and rows, detonation point selection and detonation sequence, all of which have different degrees of influence on the blasting quality.

[0063] One of the important indicators for measuring the economic benefits of blasting is the unit consumption of explosives used for blasting. The phenomenon of high actual unit consumption of explosives in mines has affected the economic benefits of mines to a certain extent. In order to achieve cost reduction and efficiency improvement in the blasting process, on the basis of ensuring the quality of open-pit mine blasting, the embodiment of the present application can adopt relevant measures to further reduce the unit consumption of explosives for open-pit blasting. In this regard, in a method for controlling deep hole blasting in an open-pit coal mine provided in an embodiment of the present application, step S40 "evaluating the effects of candidate blasting schemes to generate a blasting scheme for the area to be blasted" also includes the following steps:

[0064] Based on the rock mass blastability classification and explosive matching, the explosive consumption in the blasting plan of the blasting area is optimized.

[0065] In the embodiment of the present application, a geological information management system with blasting auxiliary function and a rock blastability classification model can be established. Through field tests and laboratory measurements, the rock wave impedance is calculated and matched with the explosive wave impedance, the type of explosive and unit consumption are reasonably selected, and the explosive energy is efficiently used. Specifically, a rock blastability classification model is established considering the blastability of the rock mass of the stripping step of the open-pit coal mine, and then, considering the influence of the rock structure surface of the stripping step in the area to be blasted and the physical and mechanical properties of the rock strata on the blasting effect, the blastability classification corresponding to the first geological feature is determined based on the rock blastability classification model, so as to determine the corresponding rock wave impedance, and the explosive unit consumption is selected by matching it with the explosive wave impedance of different explosives.

[0066] The geological information management system can realize the functions of importing, editing, viewing and outputting data such as the rock types and their physical and mechanical properties, topographic and geomorphic characteristics, and rock structure characteristics of the mining area.

[0067] It should be noted that according to the relevant literature on blasting theory, when the wave impedance of the rock mass matches the wave impedance of the explosive, the energy transmitted to the rock mass by the explosive is the largest, the strain value caused in the rock mass is the largest, and a better blasting effect can be obtained. According to the rock mass conditions of the quarry, a group of rock mass samples are taken for rock mass wave velocity testing. In rock mass classification, the elastic wave method has become an indispensable means. The main parameters for rock mass classification using elastic waves are: wave velocity, integrity coefficient, weathering coefficient, and crack coefficient. Generally speaking, a fast wave propagation speed in a rock mass indicates that the rock mass is dense, hard, complete, and lightly weathered. On the contrary, a low wave velocity indicates that the rock mass is loose, weak, broken, structurally developed, and severely weathered.

[0068] In one possible implementation, a blasting plan can be simulated for a blasting area where the geological type is first realized. Figure 3 , Figure 3 Another schematic diagram of a process flow of a deep hole blasting control method for an open-pit coal mine provided in an embodiment of the present application. Figure 3 As shown, an open-pit coal mine deep hole blasting control method provided in an embodiment of the present application also includes the following steps:

[0069] S50: If there is no target blasting area, a blasting plan for the area to be blasted is generated by performing simulation analysis based on the first geological feature.

[0070] In the embodiment of the present application, if the target blasting area does not exist in the blasting record, ANSYS / LS-DYNA software can be used to perform numerical calculations on the step blasting under different blasting schemes to reveal its mechanism of action on the blasting effect; at the same time, a comparative analysis of the blasting effects of different blasting schemes is performed to provide a theoretical basis for on-site blasting optimization plans.

[0071] In a possible implementation, in order to realize the visualized operation of blasting, a method for controlling deep hole blasting in an open-pit coal mine provided in an embodiment of the present application further includes the following steps:

[0072] Blasting design and simulation are carried out based on the blasting plan of the area to be blasted.

[0073] The embodiment of the present application can establish an intelligent blasting optimization design system, realize template management of blasting design, establish a design parameter database, and provide basic data for blasting effect prediction.

[0074] In long-term production practice and scientific experiments, using the latest testing methods, through a large number of blasting simulation tests, the stress, strain, rupture and flying phenomena inside and outside the rock mass during the blasting process were observed and measured, and further research results on the rock mass crushing mechanism under blasting were obtained. Various hypotheses and calculation formulas were proposed. They all reflect certain objective laws and have certain guiding significance and application value for actual engineering blasting. All these have enabled us to understand the nature of rock mass medium crushing, and consciously use its crushing laws to guide engineering practice, so as to achieve the purpose of improving blasting effect.

[0075] In the embodiment of the present application, a computer 3D graphics platform suitable for loose blasting design can be developed, and the functions include drawing, editing, three-dimensional view display, visualization operation of blasting design and simulation, etc. The fast intelligent blasting design and simulation in a 3D environment include blasting area division, hole layout and charge design, connection design, blasting process simulation, blasting design template management, explosives and pyrotechnics template management, etc., creating a complete intelligent optimization solution for safe and efficient blasting in open-pit mines.

[0076] In addition, the application can also perform statistical analysis and report output. Specifically, it can statistically output information such as the volume of blasted rock, the amount of explosives and pyrotechnics used, the unit consumption of explosives, hole network parameters, charging structure, hole layout location, the amount of explosives to be detonated once, and the number of blast holes.

[0077] In practical applications, we can collect and organize data such as the surface morphology, landform distribution, and topographic contour maps of the mining area, as well as survey and statistical analysis of the morphological characteristics and slope size of the micro-topography in the blasting area. Use GPS equipment to accurately measure the location of the blasting area, the location of the drill hole, the hole depth, etc., and connect with the software to achieve accurate hole layout. GPS positioning is 30% more accurate than the level measurement. Improve the loosening blasting effect, reduce the cost of perforating blasting by 0.05 yuan / m3 on the original basis, reduce the large block rate of loosening blasting by an average of 10%, and reduce the root sill.

[0078] In actual scenarios, we can comprehensively use advanced technical methods in object-oriented (OOP) technology, geographic information system (GIS) technology, virtual reality (VR) technology, etc., apply the development model advocated by software engineering in system design, and adopt design methods such as seamless integration of graphics and data, visualization technology, integration of data flow and control flow, and software functional componentization; use controls, ODBC, DirectX and other technologies in software code implementation projects to develop a digital intelligent design system for blasting with advanced concepts and practical technologies.

[0079] Through the above description, the open-pit coal mine deep hole blasting control method provided by the embodiment of the present application serves the daily blasting design operation of the mine, provides accurate data and design for blasting construction, and improves the efficiency of blasting design work. By studying the principle of deep hole blasting on the steps of open-pit mines, analyzing the influence mechanism of geological conditions, blasting design parameters, etc. on the blasting effect, a blasting optimization plan is proposed according to the actual situation of the mine, and the intelligent combination of blasting design and geological information is realized, so that each blasting design can be accurately targeted at the rock formation in the blasting area, making the blasting design more reasonable, scientific, and accurate. It can effectively solve the problems of high rate of large blocks in mine blasting or over-crushing of blasting, the existence of foundation of blasting piles, and the existence of umbrella eaves on the upper part of the steps after blasting.
