Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, and in particular to an open-pit coal mining processing method and device. Background Art

[0002] The slope angle of the working side of an open-pit coal mine affects the amount of advance stripping. The traditional working side slow-wall mining has a small working side slope angle, which leads to an increase in the amount of advance stripping and an increase in the production stripping ratio. Combined steps are an important method to achieve steep working side mining, that is, the working side steps are divided into several groups. In each group, there is a working flat plate with the minimum working flat plate width, and the width of the remaining steps is reduced to the non-working flat plate width, reducing the horizontal projection length of the working side. The excavator is concentrated on the working flat plate. The excavator mines each step from top to bottom in the group. When the excavator mines the last step in the group, it returns to the first step to work and strip the next stripping belt. The number of combined steps is inversely proportional to the size of the working side slope angle. The more combined steps there are, the greater the working side slope angle is, the less advance stripping is, the lower the production stripping ratio is, the higher the production capacity of the open-pit mine is, the more equipment is required, and the equipment layout will be restricted during combined step mining, which will affect the production capacity of the open-pit coal mine.

[0037] Figure 2 Flow chart of the open-pit coal mining processing method according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0038] Step S202, determining the mining demand information of the target coal mine, wherein the mining demand information includes: mining operation requirement information of the target coal mine, and mining capacity requirement information of the target coal mine.

[0039] In this embodiment, by understanding the mining demand information of the target coal mine, a more scientific and reasonable mining plan can be formulated to maximize the mining efficiency and production capacity of the coal mine.

[0041] It should be noted that the mining operation requirement information of the above-mentioned target coal mine may include but is not limited to the above-mentioned contents, which will not be repeated here.

[0042] Step S204, after determining multiple sections of the working side of the target coal mine according to the mining demand information, the working side is evenly divided into multiple sections with the two side ends of the working side as endpoints.

[0043] In this embodiment, by evenly dividing the working gang into multiple sections, the mining progress and coal output of each section can be effectively controlled to avoid excessive accumulation of coal in the mine, which may cause safety hazards. By dividing the working gang into multiple sections, the mining process can be better organized and managed, the mining efficiency can be improved, and the full utilization of coal mine resources can be ensured.

[0044] Step S206 , sorting the multiple segments according to a predetermined order, and adding labels to the sorted multiple segments to obtain multiple labeled segments.

[0045] In this embodiment, multiple sections are sorted in a predetermined order and marked with labels, so that the ore mining process can be managed more effectively. By sorting the sections, it is possible to ensure that mining is carried out in the correct order, thereby improving mining efficiency and safety. Adding labels can accurately identify each section and avoid confusion and erroneous operations, thereby effectively organizing and monitoring the mining process.

[0046] Step S208, controlling the mining equipment of the target coal mine to mine the working section from the first section of the multiple identified sections as the starting end until the last section of the multiple identified sections is mined.

[0047] In this embodiment, by mining in the order of the marked sections, the mining process of the coal mine can be ensured to be orderly, confusion and wrong mining sequence can be avoided, the safety and stable mining of the mine can be ensured, and the mining progress and scope of the coal mine can be effectively controlled.

[0048] Through the above steps, the mining demand information of the target coal mine is determined, wherein the mining demand information includes: the mining operation requirement information of the target coal mine, the mining capacity requirement information of the target coal mine; after determining the multiple sections of the working wall of the target coal mine according to the mining demand information, the working wall is evenly divided into multiple sections with the two side end walls of the working wall as the endpoints; the multiple sections are sorted in a predetermined order, and identifications are added to the sorted multiple sections to obtain multiple identification sections; the mining equipment of the target coal mine is controlled to mine the working wall from the first section of the multiple identification sections as the starting end until the last section of the multiple identification sections is mined, so as to achieve the purpose of dividing the working wall into different sections with the two side end walls of the mining site as the endpoints, mining by adopting the combined step mining method, advancing step by step from top to bottom, so that the steep wall mining section and the slow mining section are mined alternately, thereby achieving the technical effect of local steep wall mining of the working wall of the open-pit coal mine, and improving the efficiency and reliability of mining.

[0049] The technical solution provided by the embodiment of the present invention solves the technical problem in the related art that the equipment layout is easily restricted during combined bench mining, which affects the production capacity of the open-pit coal mine and affects the mining efficiency of the open-pit coal mine.

[0050] According to the above embodiment of the present invention, multiple sections of the working gang of the target coal mine are determined based on the mining demand information, including: determining the working line length corresponding to the working gang; determining the minimum working line length of the mining equipment; determining the number of sections of the working gang based on the working line length and the minimum working line length; dividing the working gang into multiple sections according to the number of sections.

[0051] In this embodiment, the working line length corresponding to the working gang is determined to ensure the order of the working area in the mine, and the minimum working line length of the mining equipment is determined to ensure the normal operation and operating efficiency of the equipment. The number of sections of the working gang is determined according to the working line length and the minimum working line length, which can effectively plan and manage the mining operations in the mine. Dividing the working gang into multiple sections can arrange and dispatch operations in a targeted manner, thereby improving overall mining efficiency and safety.

[0052] Figure 3 Schematic diagram of work area division according to an embodiment of the present invention. Figure 3 As shown in the figure, the working area is divided into several sections according to the operation requirements and production capacity requirements. The length of the working line is L. The section length is determined according to the minimum working line length of the open-pit mining equipment selected. min , then the number of sections that the work group can be divided into is i (i = 1, 2, 3, ..., n), and the calculation method of the number of sections i is:

[0053] According to the above embodiment of the present invention, after sorting multiple sections in a predetermined order and adding labels to the sorted multiple sections to obtain multiple identified sections, the open-pit coal mine mining processing method also includes: determining that the first section among the multiple identified sections is a steep wall mining section, and determining that the last section among the multiple identified sections is a gentle wall mining section.

[0054] In this embodiment, determining that the first section among multiple identified sections is a steep wall mining section and the last section is a gentle wall mining section can ensure safe and efficient mining of the mine. The steep wall mining section is usually a slope or steep slope section in a coal mine, which is suitable for high-yield coal mining, while the gentle wall mining section is usually a flat section, which is suitable for transportation and processing of coal. By clearly distinguishing between the steep wall mining section and the gentle wall mining section, the coal mining process can be made more orderly and efficient.

[0055] Figure 4 Schematic diagram of steep slope mining in section 1 according to an embodiment of the present invention, Figure 4 As shown, with the two side end walls as endpoints, the working wall is divided into three parts equally, namely Section 1, Section 2 and Section 3. Section 1 on the left side of the working wall is set as the steep wall mining section, and the upper stripping step adopts the combined step mining method. The two stripping steps are divided into a group, one of which retains the minimum working flat plate width, and the other step retains the non-working flat plate width. The right side of the working wall is set as the gentle wall mining section, and each flat plate retains the minimum working flat plate width.

[0056] According to the above embodiment of the present invention, in the case that there are three multiple sections, the multiple sections include: a first section, a second section and a last section, and the mining equipment of the target coal mine is controlled to start from the first section of the multiple identified sections, and to perform mining processing on the working wall until the last section of the multiple identified sections is mined, including: after the mining equipment advances forward a predetermined length in the first section, determining that the first section is converted into a gentle wall mining section, and the second section is converted into a steep wall mining section; in the process of the mining equipment mining the second section, if the mining equipment advances forward a predetermined length, determining that the second section is converted into a gentle wall mining section, and the last section is converted into a steep wall mining section; repeating the above steps to mine the first section, the second section and the last section until the last section is mined.

[0057] In this embodiment, by converting different sections into gentle-slope mining sections and steep-slope mining sections respectively, the performance of the mining equipment can be fully utilized to improve mining efficiency and safety. Repeated mining of each section can maximize the mining rate of coal resources and ensure that coal resources are fully utilized. The geological conditions and coal seam characteristics of different sections can be effectively utilized to achieve efficient mining of coal resources.

[0058] Figure 5 Schematic diagram of 2-section steep slope mining according to an embodiment of the present invention, Figure 5 As shown, when the working wall and steep wall mining section advance forward 50m (i.e., the predetermined length), Section 1 (i.e., the first section) becomes the gentle wall mining section, each flat plate retains the minimum working flat plate width, and Section 2 (i.e., the second section) becomes the steep wall mining section, which is mined using the combined step method.

[0059] Figure 6 3 is a schematic diagram of steep slope mining in three sections according to an embodiment of the present invention, as shown in FIG. Figure 6 As shown, when the steep wall mining section in the middle of the working wall advances 50m, Section 2 becomes a gentle wall mining section, each flat plate retains the minimum working flat plate width, and Section 3 (i.e., the last section) becomes a steep wall mining section, which is mined using the combined step method.

[0060] Figure 7 Schematic diagram of optional steep slope mining in Section 1 according to an embodiment of the present invention, Figure 7 As shown, according to the layout of the surface system of the open-pit mine, the position of the steep wall mining section can be flexibly adjusted. For example, after completing a mining cycle of steep wall mining in section 3, it is restored to the gentle wall mining section, and section 1 is set as the steep wall mining section. After that, each section alternates with steep wall mining.

[0061] It should be noted that the above-mentioned mining takes three sections as an example. The mining sections may include but are not limited to three sections, which can be adjusted according to the actual project. Open-pit coal mines have large production capacity and a large number of sections. The purpose of the above-mentioned alternation is to ensure that the advancement of the working gang and the inner row is consistent and to release the inner row space.

[0062] Figure 8 Schematic diagram of optional work area division according to an embodiment of the present invention. Figure 8 As shown in the figure, the working area is divided into several sections according to the operation requirements and production capacity requirements. The length of the working line is L. The section length is determined according to the minimum working line length of the open-pit mining equipment selected. min , then the number of sections that the work group can be divided into is i (i=1,2,3,…,n).

[0063] This embodiment is described by taking three sections as an example. Fig. 9 Schematic diagram of the mining equipment mobilization according to an embodiment of the present invention, such as Fig. 9As shown, with the two side end walls as endpoints, the working wall is divided into three parts equally, namely Section 1, Section 2 and Section 3. Section 1 on the left side of the working wall is set as the steep wall mining section, and the upper stripping step adopts the combined step mining method. The two stripping steps are divided into a group, one of which retains the minimum working flat plate width, and the other step retains the non-working flat plate width. The right side of the working wall is set as the gentle wall mining section, and each flat plate retains the minimum working flat plate width.

[0064] It should be noted that since steep wall mining will affect the advancement rate, the steep wall mining section has certain requirements on the number of equipment. When the advancement rate of Section 1 and Sections 2 and 3 is quite different, Sections 2 and 3 need to transfer some equipment to the steep wall mining section to increase the advancement rate of the steep wall mining section, realize dynamic regulation of the production stripping ratio, and reduce the impact on production organization.

[0065] According to the above embodiment of the present invention, the upper stripping steps of multiple sections adopt a combined step mining method, and every two of the upper stripping steps are divided into a group, wherein one of every two upper stripping steps retains the minimum working flat plate width, and the other step retains the non-working flat plate width.

[0066] In this embodiment, by combining the step mining method, miners can be more stable and safe when performing mining operations. The design of retaining the minimum working flat plate width and non-working flat plate width can ensure that miners have enough space to work while reducing waste and losses in the coal mining process.

[0067] The technical solution provided by the above embodiment of the present invention solves the following problems: Under the existing working ridge slow ridge mining conditions, the amount of advanced stripping is large during the advancement of the working ridge, the production stripping ratio increases, and the economic benefits are reduced. If the overall steep ridge mining method of the working ridge is adopted, although the production stripping ratio can be reduced, it will affect the production capacity of the open-pit coal mine and increase the difficulty of production organization and management, especially in open-pit coal mines with large production capacity. It is more difficult to implement. At the same time, it has the following beneficial effects: the working ridge is divided into different sections, and the local steep ridge mining of the working ridge is realized by controlling the width of the flat plate in different sections and adjusting the mining procedure. Under the conditions of ensuring the production organization of the open-pit coal mine, especially under the influence of increased production capacity and increased number of equipment, the production stripping ratio is reduced and the economic benefits are improved.

[0068] As can be seen from the above, in the embodiment of the present invention, the end walls on both sides of the mining field are used as endpoints to divide the entire working wall into several mining sections. Among them, the width of the working flat plate in the slow wall mining section is greater than or equal to the minimum working flat plate width, and the steep wall mining section adopts a combined step mining method, and the working wall steps are divided into several groups. In each group of steps, only one flat plate has the minimum working flat plate width, and the widths of other flat plates are reserved according to the width of the non-working flat plate. When the working flat plate completes the operation of a mining belt, the step changes from a working step to a non-working step, and the flat plate width is adjusted to the non-working flat plate width. The next step changes from a non-working step to a working step, and all equipment moves to the next step, and the width is adjusted to the minimum working flat plate width. Mining is carried out step by step from top to bottom. When all steps in the group are advanced 50m forward, the slow mining section becomes the steep wall mining section, and the steep wall mining section becomes the slow mining section. The steep wall mining section and the slow mining section are mined alternately.

[0069] That is, the technical solution provided by the embodiment of the present invention comprehensively considers various factors, mines steep walls in some sections of the working wall, and combines it with other slow mining sections to reduce the amount of advanced stripping, while reducing the production stripping ratio and taking into account production organization and management, thereby improving the economic benefits of the mine. The slope angle of the working wall in some sections can be directly increased through the local steep wall mining procedure of the working wall, while reducing the amount of advanced stripping and reducing the production stripping ratio while considering the difficulty of production organization and management, thereby effectively improving the economic benefits of the mine.
