[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0044] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0045] Figure 1 A flow chart of a method 100 for processing a message according to an embodiment of the present disclosure is shown. The method 100 may include:
[0046] Step 110, obtaining historical coal mining depths and corresponding historical mining height thresholds, wherein the historical mining height thresholds are used to represent mining height reference values;
[0047] The historical mining height threshold is used to characterize the mining height reference value, and the historical mining height may be far away from or close to the mining height reference value, so as to confirm how to reduce the impact on the surface by statistically analyzing the actual surface subsidence coefficient when the historical mining height is far away from or close to the historical mining height threshold.
[0048] The historical coal mining depth may be the mining depth of any coal seam, for example, the mining depth of the first coal seam and the mining depth of the second coal seam in a mining area, and the corresponding historical mining height threshold is also the mining height threshold of any coal seam.
[0049] There may be multiple historical coal mining depths, and similarly, there may be multiple historical mining height thresholds corresponding to each historical coal mining depth. Since the coal mining depths in each region may be similar, or the coal mining depths in multiple regions may be the same, each historical mining height threshold may be applicable to a certain region or multiple regions. For example, coal mines in the Northeast may be applicable to mining height threshold A, and coal mines in North China and Northwest China may be applicable to mining height threshold B.
[0050] Step 120, obtaining a target corresponding relationship between the mining depth and the mining height threshold according to the historical coal mining depth and the corresponding historical mining height threshold;
[0051] Specifically, by fitting the function of the multiple historical coal mining depths and the corresponding multiple historical mining height thresholds, the target corresponding relationship between the mining depths and the mining height thresholds can be accurately obtained. Of course, the fitting tool can be an existing one, and the historical coal mining depths and the historical mining height thresholds corresponding to the historical coal mining depths are input into the fitting tool in groups, and multiple groups are continuously input to fit the target corresponding relationship. Of course, the fitted relationship can be linear or nonlinear, and the present disclosure does not limit it.
[0052] For example, if the mining depth is H and the mining height threshold is M, by counting multiple historical H and their corresponding M, and then fitting, we can get The greater the mining depth H, the greater the corresponding mining height threshold M. Figure 2 As shown, it can be foreseen that the mining depth will be 100m to 1300m, and the corresponding mining height threshold will be 3m to 6m.
[0053] In addition, after obtaining the target corresponding relationship, the above historical coal mining depth can be input into the target corresponding relationship to regain a historical mining height threshold, and the regained historical mining height threshold is the corrected historical mining height threshold corresponding to the historical coal mining depth.
[0054] It is found through statistics that the mining surface corresponding to each mining height threshold is in the state of maximum subsidence coefficient, that is, each mining height threshold corresponds to the maximum surface subsidence coefficient (that is, the maximum surface subsidence height), and the maximum surface subsidence coefficient is also the most unfavorable mining height. Therefore, the maximum surface subsidence coefficient corresponding to the corrected historical mining height threshold can be determined through multiple historical mining height thresholds and the maximum surface subsidence coefficient under each historical mining height threshold. Then, according to the historical mining height corresponding to the historical coal mining depth, the corrected historical mining height threshold and the corresponding maximum surface subsidence coefficient, the coal mining height is adjusted to avoid the coal mining height reaching the most unfavorable surface subsidence coefficient and causing adverse effects on the surface to the greatest extent, thereby optimizing mining and reducing the impact on the ecological environment.
[0055] Step 130: According to the target corresponding relationship, the mining height of the coal is adjusted. The mining height is the mining height.
[0056] The mining height may be a preliminary preset mining height during coal mining or in the process of coal mining. The mining height may not be appropriate and may easily affect the ecological environment. Therefore, the mining height of the coal may be increased or decreased.
[0057] Specifically, the actual thickness of the coal and the current mining mechanization level can be confirmed; then, according to the actual thickness of the coal, the mining height and the current mining mechanization level, the mining height can be increased or decreased, wherein reducing the mining height includes: directly reducing the mining height or reducing the mining height by filling replacement.
[0058] The actual thickness of the coal, i.e. the thickness of the coal seam where the coal is currently located, can be detected in advance. The current mining mechanization level can be the quotient of the coal output that can be mined using the mining equipment divided by the total coal output obtained after mining the current coal seam.
[0059] Specifically, if the mining height is less than the actual thickness, and the difference between the actual thickness and the mining height is greater than a preset threshold, the mining height is increased; conversely, if the mining height is less than the actual thickness, and the difference between the actual thickness and the mining height is less than a preset threshold, the mining height is reduced. And / or
[0060] If the current mining mechanization level is greater than the preset mining mechanization level, the mining height is increased; otherwise, the mining height is reduced.
[0061] Reducing the mining height includes: directly reducing the mining height or reducing the mining height by filling and replacement. Reducing the mining height by filling and replacement means that mining is still carried out according to the mining height, but after mining, sand, mud, cement slurry, gravel, etc. are filled into the mining area to reduce the mining height in disguised form, thereby reducing the mining height by filling and replacement, thereby achieving mining height optimization.
[0062] After obtaining the historical coal mining depths and the corresponding historical mining height thresholds, the target correspondence between the mining depths and the mining height thresholds can be obtained based on the historical coal mining depths and the corresponding historical mining height thresholds. Then, based on the target correspondence, the coal mining height can be automatically adjusted, thereby optimizing coal mining by optimizing the coal mining height and reducing damage and impact on the ecological environment.
[0063] In some embodiments, obtaining a target corresponding relationship between mining depth and mining height threshold according to the historical coal mining depth and the corresponding historical mining height threshold includes:
[0064] Function fitting is performed on the plurality of historical coal mining depths and the corresponding plurality of historical mining height thresholds to obtain a target corresponding relationship between the mining depths and the mining height thresholds.
[0065] By inputting each historical coal mining depth and the historical mining height threshold corresponding to each historical coal mining depth into the fitting tool in groups, and continuously inputting multiple groups, the target corresponding relationship can be fitted, so as to facilitate the subsequent prediction of the mining height threshold based on the coal mining depth.
[0066] Of course, the fitting can be linear or nonlinear, and the present disclosure does not limit this.
[0067] For example, if the mining depth is H and the mining height threshold is M, by counting multiple historical H and their corresponding M, and then fitting, we can get The greater the mining depth H, the greater the corresponding mining height threshold M. Figure 2 As shown, it can be foreseen that the mining depth will be 100m to 1300m, and the corresponding mining height threshold will be 3m to 6m.
[0068] Among them, in the above formula, K is the overburden characteristic coefficient (related to the thickness of the loose layer such as soil / sand below the surface and above the rock, or K = loose layer thickness / (rock thickness + loose layer thickness), or adjustment coefficient, ranging from 1 to 1.5, and decreasing with the increase of mining depth. For example, when the mining depth H≤400m, K is preferably 1.2, when the mining depth is 400<H<800m, K is preferably 1.1, and when the mining depth H≥800m, the K value is 1.
[0069] In some embodiments, adjusting the mining height of the coal according to the target correspondence relationship includes:
[0070] According to the target corresponding relationship, the historical mining height threshold is corrected to obtain a corrected historical mining height threshold corresponding to the historical coal mining depth;
[0071] After obtaining the target corresponding relationship, the above historical coal mining depth can be input into the target corresponding relationship to regain a historical mining height threshold, and the regained historical mining height threshold is the corrected historical mining height threshold corresponding to the historical coal mining depth.
[0072] Of course, the historical mining height threshold corresponding to a certain historical coal mining depth and the corrected historical mining height threshold corresponding to the historical coal mining depth may be equal to or slightly different.
[0073] Determine the maximum surface subsidence coefficient corresponding to the corrected historical mining height threshold;
[0074] The maximum surface subsidence coefficient is the maximum surface subsidence height, which is also the maximum height of surface subsidence.
[0075] The coal mining height is adjusted according to the historical mining height corresponding to the historical coal mining depth, the corrected historical mining height threshold and the corresponding maximum surface subsidence coefficient.
[0076] The mining surface corresponding to each mining height threshold is in the maximum subsidence coefficient state, that is, each mining height threshold corresponds to the maximum surface subsidence coefficient (that is, the maximum surface subsidence height), and the maximum surface subsidence coefficient is also the most unfavorable mining height. Therefore, according to the historical mining height corresponding to the historical coal mining depth, the corrected historical mining height threshold and the corresponding maximum surface subsidence coefficient, the coal mining height is adjusted to avoid the coal mining height reaching the most unfavorable surface subsidence coefficient and causing adverse effects on the surface to the greatest extent, thereby optimizing mining and reducing the impact on the ecological environment.
[0077] In some embodiments, the adjusting the mining height of the coal according to the historical mining height corresponding to the historical coal mining depth, the corrected historical mining height threshold and the corresponding maximum surface subsidence coefficient includes:
[0078] Calculating the absolute value of the difference between the historical mining height and the corrected historical mining height threshold;
[0079] confirming a preset corresponding relationship between the absolute value of the difference and the corresponding maximum ground subsidence coefficient;
[0080] like Figure 3As shown in the figure, when the historical mining height threshold remains unchanged, the mining height is used as the horizontal coordinate and the optimization coefficient (negatively correlated with the size of the surface subsidence coefficient, that is, the lower the optimization coefficient, the larger the actual surface subsidence coefficient, and the higher the optimization coefficient, the smaller the actual surface subsidence coefficient) is used as the vertical coordinate. It can be seen that when the mining height m = the mining height threshold M, the optimization coefficient is the lowest value and reaches the maximum surface subsidence coefficient. The farther the mining height m is from the mining height threshold M, the larger the optimization coefficient is, because Figure 3 The mining height threshold remains unchanged, that is, the larger the absolute value of the difference between the mining height threshold M and the mining height m |Mm|, the farther the relative position is, the higher the optimization coefficient is, and the better the optimization effect is. Figure 3 The mining height optimization coefficient curve shown in the figure shows that the optimization coefficient is basically distributed in a check mark (√). Figure 3 It can be seen that the larger the difference between the mining height and the threshold value (the absolute value of mM), the lower (smaller) the sinking coefficient is, and the better the mining height optimization effect is.
[0081] According to the preset corresponding relationship, the mining height of the coal is adjusted.
[0082] The absolute value of the difference can be multiple, and similarly, the corresponding maximum surface subsidence coefficient is also multiple, that is, there are multiple historical mining heights. Even if the correction threshold of the historical mining height remains unchanged, the corresponding absolute value of the difference is also multiple. In this way, by counting multiple absolute values of the difference and the maximum surface subsidence coefficient corresponding to each absolute value of the difference, the preset corresponding relationship can be accurately confirmed, and then according to the preset corresponding relationship, the mining height of the coal can be automatically and accurately adjusted, thereby reducing the impact on the ecological environment by optimizing mining.
[0083] from Figure 3 It can be seen that mining height optimization can be achieved by increasing or decreasing the mining height to move away from the mining height threshold. Therefore, mining height optimization takes the mining height threshold as the midpoint and reduces or increases the mining height accordingly.
[0084] In comparison, increasing the mining height is given priority, which can achieve a win-win situation in terms of efficiency, benefits and optimization. If this cannot be achieved due to resource thickness and equipment conditions, the mining height can be reduced to achieve mining height optimization.
[0085] There are two ways to optimize the mining height. One is limited height mining, which is to directly reduce the mining height. The other is filling mining, which achieves mining height optimization by reducing the mining height by equivalent filling replacement.
[0086] In some embodiments, adjusting the mining height of the coal according to the preset corresponding relationship includes:
[0087] Confirm the current mining depth corresponding to the current coal seam where the coal is located;
[0088] According to the target corresponding relationship, the mining height threshold corresponding to the current mining depth is calculated; the mining height threshold is the mining height threshold.
[0089] According to the preset corresponding relationship, the mining height is increased or decreased with the goal of increasing the absolute value of the difference between the current mining depth and the mining height threshold.
[0090] After obtaining the current mining depth, the current mining depth can be substituted into the target corresponding relationship, so as to calculate the mining height threshold using the target corresponding relationship, and then according to the preset corresponding relationship, the mining height is increased or decreased with the goal of increasing the absolute value of the difference between the current mining depth and the mining height threshold, so that the adjusted mining height is away from the mining height threshold, and the actual surface subsidence coefficient is less than the maximum surface subsidence coefficient.
[0091] In some embodiments, increasing the mining height or decreasing the mining height comprises:
[0092] Confirm the actual thickness of the coal and the current level of mechanization in its mining;
[0093] The mining height is increased or decreased according to the actual thickness of the coal, the mining height and the current mining mechanization level, wherein reducing the mining height includes: directly reducing the mining height or reducing the mining height by filling and replacement.
[0094] The actual thickness of the coal, i.e. the thickness of the coal seam where the coal is currently located, can be detected in advance. The current mining mechanization level can be the quotient of the coal output that can be mined using the mining equipment divided by the total coal output obtained after mining the current coal seam.
[0095] Specifically, if the mining height is less than the actual thickness, and the difference between the actual thickness and the mining height is greater than a preset threshold, the mining height is increased; otherwise, if the mining height is less than the actual thickness, and the difference between the actual thickness and the mining height is less than a preset threshold, the mining height is decreased. And / or if the current mining mechanization level is greater than a preset mining mechanization level, the mining height is increased; otherwise, the mining height is decreased.
[0096] Reducing the mining height includes: directly reducing the mining height or reducing the mining height by filling and replacement. Reducing the mining height by filling and replacement means that mining is still carried out according to the mining height, but after mining, sand mud, yellow mud, crushed gangue, etc. are filled into the mining area or the separation area to reduce the mining height in disguised form, thereby reducing the mining height by filling and replacement, thereby achieving mining height optimization.
[0097] In some embodiments, adjusting the mining height of the coal according to the preset corresponding relationship includes:
[0098] According to the preset corresponding relationship and the current coal mining attributes, the mining height of the coal is increased or decreased, wherein the current coal mining attributes include at least one of the following: coal mining size, coal mining scale, coal mining intensity, and surface movement degree. The surface movement degree includes the initial stage, active stage, and decline stage of surface movement. The actual subsidence coefficient of the surface in the initial stage of movement is less than and far away from the maximum subsidence coefficient. The actual subsidence coefficient of the active surface may be close to or equal to the maximum subsidence coefficient, and the actual subsidence coefficient of the declining surface may be slightly greater than the maximum subsidence coefficient (such as 1) or a surface movement basin has been formed.
[0099] When adjusting the mining height, you can not only adjust it according to the preset corresponding relationship, but also combine it with the current coal mining properties, so that the coal mining height can be increased or decreased more accurately.
[0100] Specifically, if it is confirmed according to the preset corresponding relationship that the mining height of coal needs to be increased, some mining heights can be adaptively adjusted according to the current coal mining attributes, such as the larger the coal mining size, coal mining scale, and coal mining intensity, the larger the space for increasing the mining height. Figure 4 The mining height optimization capability under different coal mining scales can reach a mining height optimization range of 10% to 45%.

Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required by the present disclosure.
