Abstract
Description
Technical Field
[0001] This application relates to the field of coal mining technology, and in particular to a method, apparatus and electronic equipment for determining the feasibility of coal seam upward mining. Background Technology
[0002] In related technologies, methods for determining the feasibility of upward mining are typically only applicable under conventional conditions where the distance between upper and lower coal seams and the lower coal seam mining height do not vary significantly. Under these conditions, the mining impact factor does not change much, making it relatively easy to determine the feasibility of upward mining. However, due to the complexity of coal seam geological mining conditions, the distance between upper and lower coal seams and the lower coal seam mining height vary randomly. When using methods such as the mining impact factor method, the feasibility of upward mining near the borehole can only be determined, while the feasibility of upward mining between boreholes or in the vicinity of the borehole is difficult to determine. Summary of the Invention
[0003] This application provides a method, apparatus, electronic device, and storage medium for determining the feasibility of upward coal seam mining. It can delineate the feasibility study area for upward mining, identifying feasible and infeasible zones, thus ensuring the safety and economy of upward mining.
[0004] In a first aspect, embodiments of this application provide a method for determining the feasibility of upward mining of coal seams, comprising: obtaining the borehole coordinates, inter-layer spacing between upper and lower coal seams, mineable height of the lower coal seam, and uniaxial compressive strength of boreholes in the upward mining demonstration area and adjacent areas; obtaining the boundary coordinates of the upward mining demonstration area and the slump ratio of the lower coal seam; drawing a contour map of the mining impact multiple of the upward mining demonstration area based on the borehole coordinates, the inter-layer spacing between upper and lower coal seams, the mineable height of the lower coal seam, the uniaxial compressive strength, the boundary coordinates, and the slump ratio; and determining the feasible and infeasible areas for upward mining within the upward mining demonstration area based on the contour map of the mining impact multiple of the upward mining demonstration area.

The various numerical designations such as "first", "second", etc., involved in this application are only for the convenience of description and are not used to limit the scope of the embodiments of this application, nor do they indicate the order of events.
[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of a method for determining the feasibility of upward coal seam mining provided in an embodiment of this application. Figure 1 As shown, the method may include, but is not limited to, the following steps:
[0027] Step S101: Obtain the borehole coordinates, the distance between upper and lower coal seams, the mineable height of the lower coal seam, and the lithology and uniaxial compressive strength of the strata between the upper and lower coal seams in the upward mining demonstration area and adjacent areas.
[0028] In the embodiments of this application, the aforementioned drill hole may be one or more.
[0029] For example, obtain relevant data on the mines belonging to the upward mining demonstration area and the areas within and adjacent to the upward mining demonstration area (e.g., borehole columnar sections, geological profiles, coal seam reserve distribution maps, mining engineering plans, and coal thickness contour maps of the upward mining demonstration area and adjacent areas), and obtain the corresponding borehole coordinates, interlayer spacing between upper and lower coal seams, mineable height of the lower coal seam, lithology and uniaxial compressive strength of the strata between the upper and lower coal seams for each borehole in the upward mining demonstration area and adjacent areas.
[0030] It should be noted that, in the embodiments of this application, the up-mining demonstration area refers to the target area where it is necessary to determine whether up-mining can be carried out, and the adjacent area refers to the area adjacent to the target area.
[0031] Step S102: Obtain the boundary coordinates of the upward mining demonstration area and the slump ratio of the lower coal seam.
[0032] For example, the boundary coordinates of the upward mining demonstration area are obtained by measurement, and the slump ratio of the lower coal seam in the coal seam where the upward mining demonstration area is located is obtained.
[0033] In the embodiments of this application, the boundary coordinates of the upward mining demonstration area include the boundary coordinates of the upper coal seam mineable boundary and the boundary coordinates of the lower coal seam mineable boundary.
[0034] Step S103: Based on borehole coordinates, the distance between upper and lower coal seams, the mineable height of the lower coal seam, the lithology of the strata between upper and lower coal seams, uniaxial compressive strength, boundary coordinates, and caving ratio, draw a contour map of the mining impact multiple in the upward mining demonstration area.
[0035] For example, based on the spacing between upper and lower coal seams, the mineable height of the lower coal seam, the lithology, uniaxial compressive strength, and slump ratio of the strata between upper and lower coal seams, the first mining impact multiple of the borehole is determined, and the mining impact multiple required to carry out upward mining is determined. Based on the borehole coordinates, mining impact multiple, and boundary coordinates, a contour map of the mining impact multiple of the upward mining demonstration area is drawn.
[0036] Step S104: Based on the contour map of the mining impact multiple in the upward mining demonstration area, determine the feasible and infeasible areas for upward mining in the upward mining demonstration area.
[0037] For example, in the contour map of the mining impact multiple in the upward mining demonstration area, the area corresponding to the mining impact multiple required to carry out upward mining is identified as the feasible area for upward mining, and other areas other than the feasible area for upward mining are the infeasible area for upward mining.
[0038] By implementing the embodiments of this application, based on the obtained data such as borehole coordinates, the distance between upper and lower coal seams, the mineable height of the lower coal seam, the lithology, uniaxial compressive strength, boundary coordinates, and slump ratio of the inter-coal seams, a contour map of the mining impact ratio of the upward mining demonstration area can be drawn. This allows for the division of the upward mining demonstration area, the determination of feasible and infeasible areas for upward mining, and facilitates the implementation of safety technical measures for infeasible areas, ensuring the safety and economy of upward mining.
[0039] In one implementation of this application, the first mining impact multiple of the borehole and the feasible mining impact multiple threshold for upward mining can be obtained based on the acquired data. Then, based on the borehole coordinates, boundary coordinates, mining impact multiple, and feasible mining impact multiple threshold, a contour map of the mining impact multiple in the upward mining demonstration area can be drawn. As an example, please refer to... Figure 2 , Figure 2 This is a schematic diagram of another method for determining the feasibility of upward coal seam mining provided in an embodiment of this application. Figure 2 As shown, the method may include, but is not limited to, the following steps:
[0040] Step S201: Obtain the borehole coordinates, the distance between upper and lower coal seams, the mineable height of the lower coal seam, and the lithology and uniaxial compressive strength of the strata between the upper and lower coal seams in the upward mining demonstration area and adjacent areas.
[0041] In the embodiments of this application, step S201 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.
[0042] Step S202: Obtain the boundary coordinates and cross-mining ratio of the lower and upper coal seams in the upward mining demonstration area.
[0043] In the embodiments of this application, step S202 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.
[0044] Step S203: Based on the spacing between the upper and lower coal seams and the mineable height of the lower coal seam, obtain the first mining impact factor of the borehole.
[0045] As an example, please refer to Table 1, which is a table of calculation results of mining impact multiple provided in the embodiments of this application. As shown in Table 1, the first mining impact multiple of the borehole can be obtained by dividing the distance between the upper and lower coal seams corresponding to each borehole by the corresponding minable height of the lower coal seam.
[0046] Table 1. Calculation Results of the Impact Factor of Mining
[0047]
[0048] Step S204: Based on the lithology, uniaxial compressive strength and caving ratio of the interlayer strata between the upper and lower coal seams, obtain the feasible mining impact factor threshold for upward mining.
[0049] In one alternative implementation, obtaining the feasible mining impact factor threshold for upward mining based on the lithology, uniaxial compressive strength, and caving ratio of the inter-seam strata between the upper and lower coal seams may include the following steps:
[0050] S1: Based on uniaxial compressive strength, obtain the comprehensive lithology of the strata between the upper and lower coal seams.
[0051] For example, based on the uniaxial compressive strength of each borehole, the average uniaxial compressive strength is obtained as the average uniaxial compressive strength. Based on the average uniaxial compressive strength, the lithology of the corresponding inter-layer strata between the upper and lower coal seams is obtained from the inter-layer lithology discrimination table shown in Table 2. As an example, taking an average uniaxial compressive strength of 19 MPa as an example, the overall lithology of the inter-layer strata between the upper and lower coal seams is determined to be weak.
[0052] Table 2. Lithological identification table between upper and lower coal seams
[0053]
[0054] S2: Based on comprehensive lithology, obtain the second mining impact factor.
[0055] In some embodiments of this application, when the overall lithology between the upper and lower coal seams is hard, the feasible mining influence multiple can be 8; when the overall lithology between the upper and lower coal seams is medium hard, the feasible mining influence multiple can be 7.5; when the overall lithology between the upper and lower coal seams is weak, the feasible mining influence multiple can be 7.
[0056] As an example, if the overall lithology of the rock strata between the upper and lower coal seams is weak, then the feasible mining impact factor is 7.
[0057] S3: Compare the second mining impact factor and the cross-mining ratio, and select the larger one as the feasible mining impact factor threshold.
[0058] As an example, if the feasible mining impact multiple is 7 and the cross-mining ratio is 6.5, then the selected feasible mining impact multiple threshold is 7.
[0059] Step S205: Based on borehole coordinates, boundary coordinates, mining impact multiple, and feasible mining impact multiple threshold, draw a contour map of the mining impact multiple in the uplink mining demonstration area.
[0060] For example, the mining impact multiple and feasible mining impact multiple threshold are input into Surfer software, the initial graphic is drawn using the Kriging interpolation method, and the CAD (Computer Aided Design) drawing with borehole coordinates and boundary coordinates is superimposed on the initial graphic to obtain the contour map of the mining impact multiple in the upward mining demonstration area.
[0061] Step S206: Based on the contour map of the mining impact multiple in the upward mining demonstration area, determine the feasible and infeasible areas for upward mining in the upward mining demonstration area.
[0062] In the embodiments of this application, step S206 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.
[0063] By implementing the embodiments of this application, the first mining impact multiple of the borehole and the feasible mining impact multiple threshold for upward mining can be obtained based on the acquired data. Based on the borehole coordinates, boundary coordinates, mining impact multiple, and feasible mining impact multiple threshold, a contour map of the mining impact multiple of the upward mining demonstration area can be drawn, thereby dividing the upward mining demonstration area and determining the feasible and infeasible areas for upward mining. This facilitates the implementation of safety technical measures for infeasible areas of upward mining, ensuring the safety and economy of upward mining.
[0064] In some embodiments of this application, the contour map of the mining impact multiple in the upward mining demonstration area includes contour lines corresponding to the feasible mining impact multiple threshold, the mineable boundary line of the upper coal seam, and the mineable boundary line of the lower coal seam. Based on the contour map of the mining impact multiple in the upward mining demonstration area, the feasibility of upward mining in the upward mining demonstration area is judged, including: determining that the first area enclosed by the mineable boundary line of the upper coal seam and the contour line corresponding to the feasible mining impact multiple threshold is an infeasible area for upward mining, and determining that the second area enclosed by the mineable boundary line of the lower coal seam and the contour line corresponding to the feasible mining impact multiple threshold is a feasible area for upward mining.
[0065] As an example, please see Figure 3 , Figure 3 This is an exemplary contour map of the mining impact factor in an upward mining demonstration area, provided in an embodiment of this application. For example... Figure 3As shown, taking a feasible mining impact multiple threshold of 7 as an example, the contour map of the mining impact multiple in the upward mining demonstration area includes: (1) contour lines corresponding to the mining impact multiple threshold of 7, (2) the mineable boundary line of the upper coal seam, (3) the mineable boundary line of the lower coal seam, (4) the contour lines of the mining impact multiple and the corresponding mining impact multiple, and (5) the borehole number and mining thickness. The area enclosed by the mineable boundary line of the lower coal seam and the contour lines corresponding to the feasible mining impact multiple threshold of 7 is the feasible area for upward mining. The area enclosed by the mineable boundary line of the lower coal seam and the contour lines corresponding to the feasible mining impact multiple threshold of 7 (i.e. Figure 3 The area indicated by the shading (diagonal line) is the area where upward mining is not feasible.
[0066] Please see Figure 4 , Figure 4 This is a flowchart of an uplink mining feasibility determination method provided in an embodiment of this application. For example... Figure 4 As shown, the method may include, but is not limited to, the following steps.
[0067] Step S401: Statistically calculate and analyze attributes such as borehole coordinates, distance between upper and lower coal seams, and mining thickness.
[0068] For example, the borehole coordinates, distance between upper and lower coal seams, and mining thickness of boreholes in the area and adjacent areas where the feasibility of upward mining needs to be determined are statistically analyzed and calculated.
[0069] Step S402: Obtain the mining impact factor of the borehole.
[0070] For example, the mining impact factor of each borehole is calculated based on the distance between the upper and lower coal seams and the thickness of the lower coal seam.
[0071] Step S403: Use Surfer software to draw contour maps of the mining impact factor.
[0072] For example, the Kriging interpolation method can be used to draw contour maps of the mining impact factor using Surfer software.
[0073] Step S404: Determine the threshold for feasible uplink mining.
[0074] For example, using comprehensive discrimination methods such as the mining impact multiple method and the two-zone discrimination method, multiple thresholds are determined, and the largest one is selected from the multiple thresholds as the threshold for determining the feasibility of upward mining.
[0075] Step S405: Mark the areas on the contour map of mining impact factor to indicate whether upward mining is feasible.
[0076] For example, on the contour map of mining impact multiple, areas are marked to indicate whether upward mining is feasible. When the contour value is greater than or equal to a certain threshold, upward mining is feasible in the corresponding area; when the contour value is less than the certain threshold, upward mining is not feasible in the corresponding area.
