通过对东中煤矿5线～6线采区构造特征分析,探讨了矿井构造对煤层赋存的影响,根据矿井探巷揭露的地质构造资料、地表小煤窑开采情况及结合煤岩对比分析表明,在F30断层下盘存在20,23煤层较稳定可采块段,估算了20,23煤层储量,为今后开采20,23煤层提供了理论依据。 Based on the analysis of tectonic characteristics of No.5 ~ No.6 mining area in Dongzhong Coal Mine, the influence of mine structure on the occurrence of coal seams is discussed. According to the geologic structure data, the mining situation of small coal mines and the comparison of coal and rock, There is a relatively stable recoverable block in the lower part of the fault F30. 20 and 23 coal reserves are estimated, which provides a theoretical basis for the exploitation of 20 and 23 coal seams in the future.
