针对大力公司上部一座煤层受下部山青、野青煤层多次采动影响的实际情况,运用上行开采比值判别法、“三带”判别法、数理统计法及围岩平衡法等对一座煤层5301工作面复采可行性进行分析,并对下部煤层开采后覆岩塑性区及应力场、位移场分布和工作面复采矿压显现规律进行了模拟研究,结合现场矿压监测证明极薄煤层上行复采的可行性。 In view of the fact that the upper coal seam of Dali Company is affected by the multiple mining of lower salaries and wild Qing coal seams, a method of upward mining ratio judgment, “three-zone” judgment, mathematical statistics and surrounding rock balance method The feasibility of reclamation of 5301 coal face is analyzed. The plastic zone, the distribution of stress field, displacement field and the rule of reclaiming pressure in working face after the mining of lower coal seam are simulated. Combined with the monitoring of mine pressure, it is proved that the extremely thin coal seam Feasibility of upside mining.
