Underground coal seam mining has been carried out in the Upper Silesian Coal Basin, Poland, for many years and with a simultaneous increase in exploitation depth. Frequently, coal seams are not fully extracted due to numerous reasons which lead to their edges and remnants remaining in the rock mass. Even in the case of the full extraction of a coal seam, mining usually ends at the border of a protecting pillar to protect underground or surface objects, sometimes at the border of the mining area, or some distance from the old goaf or high throw fault. Extraction of subsequent coal seams in an analogous range results in a cluster of coal seam edges remaining. In the vicinity of the mentioned remainders, the disrupted stress distribution is expected. The infraction of the aforementioned equilibrium repeatedly results in the occurrence of strong mining tremors. The observations from the studied coal seam no. 408’s longwall panel indicated that mining works are able to disturb the present stress-strain equilibrium in the area of the edges of other coal seams, even if they are located at a greater vertical distance away. The seismological parameters and distributions have been applied for this purpose.

多年来，在波兰上西里西亚煤盆地进行了地下煤层开采，同时开采深度不断增加。通常，由于许多原因导致煤层的边缘和残留物残留在岩体中，因此煤层无法完全开采。即使在完全开采煤层的情况下，采矿通常也要在保护柱的边界处结束，以保护地下或地面物体，有时是在采矿区的边界，或者是距旧采空区或高空断层一定距离的地方。 。在类似范围内提取随后的煤层会导致残留一组煤层边缘。在提到的其余部分附近，应力分布会被破坏。破坏上述平衡反复导致强烈的采矿震颤的发生。从所研究的第一个煤层观察到的结果。408的长壁面板表明，即使其他煤层的垂向距离更大，采矿工作也能扰乱其他煤层边缘区域当前的应力-应变平衡。为此已经应用了地震参数和分布。
