Description

Technical Field

[0001] The present disclosure relates to the technical field of mineral mining, and particularly to a method for establishing an optimal boundary of an open-pit mine and formulating a mining plan. Background Art

[0002] The main purpose of open-pit mine design is to find an open-pit mining boundary with a relatively low stripping ratio, achieving the goals of small investment, quick results, and relatively good initial benefits. There are many existing optimization methods, but most of them have poor effects, the results are relatively vague, or the calculation amount is huge, lacking practicality and being unable to be realized. Therefore, at present, the optimization of open-pit mine boundaries is mostly manual work, making several or dozens of plans, and selecting a relatively good plan from the made plans. The result is a large amount of work, long working hours, low automation, and low credibility of the results, causing great waste in actual work. Due to the huge stripping amount in open-pit mining production, if there is a little difference in the stripping ratio of the open-pit mine, it will cause losses of billions or even tens of billions of yuan in actual production. Therefore, boundary optimization is a key technology in open-pit mining technology. The realization of the optimal mining boundary search method will change the design process of open-pit mining, improve the economic benefits of open-pit mining, and make great contributions to all mankind.

[0003] Due to the complex formation of open-pit mines, with structures such as monoclines, synclines, and anticlines, and even a large number of faults distributed in the strata, the slope angles of different side slopes are different, the surface shapes are high and low, the strengths of different strata are different, the ore grades of different parts are different, and the mining costs vary greatly. The possible open-pit mine boundaries vary widely. To ensure the accuracy of boundary search, the formation of each side of the open-pit mine must be reconstructed into a curved surface based on the actual bench parameters, and simple curved surfaces and planes cannot be used to replace it. Due to the increase in mineral prices, the stripping ratio of the open-pit mine boundary is also increasing. Any simplification of the mining boundary may lead to too large a deviation in the results. And generating a complex actual bench curved surface has a very large amount of calculation, not to mention the even larger calculation amount and calculation time of the ore volume and rock volume in the subsequent calculations, resulting in a very long calculation amount and calculation time, making the present invention lack practicality. Therefore, a large number of algorithm improvements are needed to obtain credible results within an acceptable time, providing a reliable basis for open-pit mine design and production.

[0004] Due to the extremely large calculation amount of this technology, without optimizing the calculation method, this technology lacks practicality. The calculation of this technology is divided into three parts, namely:

[0005] 1. Generating a boundary model of the mined ore body;

[0006] 2. Generating a triangular mesh of the boundary model of the mined ore body;

[0007] 3. Calculating the ore and rock volumes within the mining boundary.

[0008] The computational workload of these three parts is extremely large. Each link consumes a large amount of time and computational resources, resulting in a relatively high cost. Summary of the Invention

[0035] The embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation of the present disclosure.

[0036] In the technical solution of the present disclosure, the acquisition, storage, use, processing, etc. of data all comply with the relevant regulations of relevant laws and regulations.

[0037] Figure 1 It is a schematic diagram of a method for establishing an optimal boundary of an open-pit mine pit according to an embodiment of the present disclosure. As Figure 1 shown, the method for establishing the optimal boundary of the open-pit mine pit includes the following steps:

[0038] S101. Obtain the geological exploration data of the target open-pit mine, and establish a three-dimensional model and a pit model of the target open-pit mine based on the geological exploration data, wherein the stripping ratio of the pit in the pit model is less than the limit stripping ratio.

[0039] The method for establishing the optimal boundary of the open-pit mine pit in the embodiments of the present application can be applied to the scenario of formulating an open-pit mine mining plan. The execution subject for establishing the optimal boundary of the open-pit mine pit in the embodiments of the present application can be the device for establishing the optimal boundary of the open-pit mine pit in the embodiments of the present application, and the device for establishing the optimal boundary of the open-pit mine pit can be set on an electronic device.

[0040] It should be noted that the stripping ratio refers to the amount of waste rock stripped per unit of useful mineral mined. In the coal mining industry, it is commonly expressed in cubic meters per ton, and in metal ore mining, it is expressed in cubic meters per cubic meter. It is an important technical and economic index for determining whether ore can be mined opencast.

[0041] It should be noted that the three-dimensional model and the pit model in the embodiments of the present disclosure are both simulation models. The pit model is arranged on the three-dimensional model to simulate the mining in the pit of the target open-pit mine.

[0042] It should be noted that the geological exploration data can include various types, which are not limited here, and specifically need to be limited according to actual design requirements. For example, the geological exploration data can include coal mine geological body structure, hydrogeological characteristics, coal seam occurrence, geomechanics, gas geology, etc. The acquisition methods for different geological exploration data can be different. It can be obtained by instrument measurement, and optionally, it can also be obtained by sample sampling and analysis of the target open-pit mine.

[0043] In the embodiments of the present disclosure, the ultimate stripping ratio is the maximum stripping ratio under the condition of meeting the preset stripping conditions. When the stripping ratio is greater than the ultimate stripping ratio, further mining at this time is not economically viable.

[0044] It should be noted that the ultimate stripping ratio is set in advance and can be set manually or calculated based on the actual situation of the target open-pit mine, and there is no specific limitation here. For example, the required ultimate stripping ratio for open-pit mining can be 5 - 6 cubic meters per cubic meter.

[0045] S102. Conduct a single stripping simulation operation on the open-pit mine and calculate the stripping ratio of the mined materials generated by the current stripping simulation operation.

[0046] In the embodiments of the present disclosure, after establishing the three-dimensional model and the open-pit mine model, simulated mining operations can be carried out by comparing the open-pit mine in the open-pit mine model with that in the three-dimensional model.

[0047] It should be noted that the mining thickness of a single mining operation is set in advance and can be changed according to actual design requirements, and there is no specific limitation here.

[0048] After completing the current stripping simulation operation, the stripping ratio of the current stripping simulation operation can be obtained by analyzing the stripping data.

[0049] S103. In response to the stripping ratio being greater than the ultimate stripping ratio, adjust the shape of the mining slope of the current stripping simulation operation until the stripping ratio of the adjusted current stripping operation is less than or equal to the ultimate stripping ratio, and then continue with the next stripping simulation operation.

[0050] S104. Repeat the above steps of conducting a single stripping simulation on the open-pit mine, calculating the stripping ratio of the current stripping simulation and its subsequent steps until the termination condition is reached, and then output the optimal boundary of the open-pit mine.

[0051] It should be noted that the termination condition can be various and is set in advance, and there is no specific limitation here. For example, the termination condition can be reaching the preset number of stripping simulation times, reaching the preset stripping simulation time, or being unable to make the stripping ratio less than the ultimate stripping ratio no matter how the open-pit mine is optimized.

[0052] In an embodiment of the present disclosure, first, geological exploration data of a target open-pit mine is obtained, and a boundary model of the target open-pit mine is established based on the geological exploration data. The boundary model includes a mining pit, and the stripping ratio of the mining pit is less than the stripping ratio threshold. Then, a single stripping simulation operation is performed on the mining pit, and the stripping ratio of the mined material generated in the current stripping simulation operation is calculated. Then, in response to the stripping ratio being greater than the stripping ratio threshold, the shape of the mining slope for stripping in the current stripping simulation operation is adjusted until the stripping ratio of the adjusted current stripping operation is less than or equal to the stripping ratio threshold, and the next stripping simulation operation is continued. Finally, the above steps of performing a single stripping simulation on the mining pit and calculating the stripping ratio of the current stripping simulation and subsequent steps are repeated until an end condition is reached, and the optimal boundary of the mining pit is output. Thus, by establishing a three-dimensional model and a mining pit model of the target open-pit mine and performing stripping simulation, and by setting the limit stripping ratio, the optimal boundary of the mining pit under the limit stripping ratio can be determined quickly and accurately. Compared with the method of determining the optimal boundary through a limited number of schemes in the prior art, this technology realizes a method for theoretically obtaining the optimal boundary of an open-pit mine, and through the corresponding optimization algorithm, the feasibility of this technology is realized, greatly improving the actual economic benefits of open-pit mining.

[0053] In a possible implementation manner, the end condition is that the stripping ratio of a single stripping simulation operation is greater than the limit stripping ratio, and the stripping ratio corresponding to the adjusted stripping simulation operation until a preset moving step is greater than the limit stripping ratio.

[0054] It should be noted that the preset moving step can be changed according to actual design needs and is not limited here. For example, the preset moving step can be 0.5 meters, 1 meter, etc.

[0055] In the above embodiment, to adjust the shape of the mining slope for stripping in the stripping simulation operation, it can also be through Figure 2 Further explanation, this method includes:

[0056] S201, restore the mining pit to the state before the current stripping simulation operation, and randomly or according to preset constraint conditions, generate candidate shapes of the mining slope for stripping.

[0057] S202, perform a stripping simulation operation according to the candidate shape of the mining slope for stripping.

[0058] It should be noted that the number of times of generating candidate shapes of the mining slope for stripping randomly can be set in advance, and candidate shapes of the mining slope for stripping are randomly generated within the preset number of times.

[0059] In the above embodiment, to adjust the shape of the mining slope for stripping in the stripping simulation operation, it can also be through Figure 3 Further explanation, this method includes:

[0060] S301, Restore the mined pit to the state before the current stripping simulation operation, and optimize the shape of the mining slope of the stripping in the current stripping simulation operation through an optimization function to obtain an optimized mining slope shape.

[0061] It should be noted that there can be multiple optimization functions, and no specific limitation is made here. The optimization function is pre-designed and can be changed according to actual design needs, and no specific limitation is made here.

[0062] S302, Perform a stripping simulation operation according to the candidate mining slope shape.

[0063] Figure 4 This is a flowchart of a method for formulating an open-pit mine pit mining plan according to the present disclosure. As Figure 4 shown, the method includes:

[0064] S401, Obtain the optimal boundary of the mined pit of the target open-pit mine.

[0065] It should be noted that the optimal boundary of the mined pit of the target open-pit mine is established by the method for establishing the optimal boundary of the open-pit mine pit in the Figures 1-3 embodiment.

[0066] S402, Formulate an open-pit mine pit mining plan based on the optimal boundary.

[0067] In the embodiment of the present disclosure, after obtaining the optimal boundary of the mined pit of the target open-pit mine, a boundary model of the ore body to be mined can be generated through the optimal boundary, and then a triangulation network of the boundary model of the ore body to be mined is generated, and finally the ore and rock volume within the mining boundary is calculated. Then, based on the triangulation network of the mining body boundary model, the ore and rock volume within the mining boundary, and the boundary model, an open-pit mine pit mining plan is formulated. While ensuring the stripping ratio, the mining difficulty is reduced as much as possible, thereby reducing the mining cost.

Since the apparatus for establishing the optimal boundary of the open-pit mine pit provided in the embodiment of the present disclosure corresponds to the methods for establishing the optimal boundary of the open-pit mine pit provided in the above several embodiments, the implementation manners of the above methods for establishing the optimal boundary of the open-pit mine pit are also applicable to the apparatus for establishing the optimal boundary of the open-pit mine pit provided in the embodiment of the present disclosure, and will not be described in detail in the following embodiments.

[0069] Figure 5 This is a schematic diagram of an apparatus for establishing the optimal boundary of an open-pit mine pit according to an embodiment of the present disclosure. As Figure 5 shown, the apparatus 500 for establishing the optimal boundary of the open-pit mine pit includes: an acquisition module 510, a stripping module 520, an adjustment module 530, and an output module 540.

[0070] An acquisition module 510 is configured to acquire geological exploration data of a target open-pit mine and establish a three-dimensional model and a pit model of the target open-pit mine, wherein the stripping ratio of the pit in the pit model is less than the limit stripping ratio.

[0073] An output module 540 is configured to repeat the above single stripping simulation of the pit, calculate the stripping ratio of the current stripping simulation and its subsequent steps until a termination condition is reached, and output the optimal boundary of the pit.

[0074] In an embodiment of the present disclosure, the adjustment module 530 is further configured to: restore the pit to the state before the current stripping simulation operation, randomly or according to preset constraint conditions generate candidate mining slope shapes; and perform a stripping simulation operation according to the candidate mining slope shapes.

[0076] By establishing a three-dimensional model and a pit model of the target open-pit mine, and performing stripping simulations, and setting the limit stripping ratio, the optimal boundary of the pit under the limit stripping ratio can be determined quickly and accurately. Compared with the prior art method of determining the optimal boundary through a limited number of schemes, this technology realizes a method for theoretically obtaining the optimal boundary of the open-pit mine, and through corresponding optimization algorithms, the feasibility of this technology is realized, greatly improving the actual economic benefits of open-pit mining.
