本文根据在金刚煤矿矿压观测和相似模拟研究结果,提出在缓倾斜近距煤层联合开采时,上下煤层的相互影响.上煤层周期性矿压显现对下煤层影响与上覆岩层形成的平衡结构特征有关.按一定错距,下煤层开采有可能使其成为非稳定结构,矿压显现加剧。一定距离内能形成稳定结构,但移动量由联合开采煤层总厚变决定,支架阻力不够,控顶区会形成危险结构,导致冒顶发生。有限元数学模拟进一步证实和发展了上述论点. Based on the results of rock pressure observation and similar simulation in Jingang Coal Mine, this paper proposes the interaction between the upper and lower coal seams when the gentle inclined coal seam is co-developed, and the influence of the periodical pressure of upper coal seam on the coal seam and the balance structure of the overlying rock formation According to certain faults, it is possible to make it an unstable structure under the mining of coal seam and the occurrence of mine pressure is aggravated. A stable structure can be formed within a certain distance, but the amount of displacement is determined by the total thickness variation of coal seam mining. The resistance of the support is not enough, and the dangerous roof structure will be formed in the roof control zone, leading to roof fall. Finite element mathematical simulation further confirmed and developed the above argument.
