摘要
观音堂矿区主要可采煤层为二1煤,矿区内断裂发育,含煤地层赋存格局受到构造制约。在分析区域构造及演化特征的基础上,依据钻孔和矿井地质资料,总结观音堂矿区地质构造发育特征以及其对煤层厚度、煤层开采的影响,对今后规划矿井采区、布置巷道工作面及矿井安全生产均有指导意义。
The main minable coal seam is II1 coal seam in Guanyintang mine area. The fracture is developed and the occurrence pattern of coal-bearing strata is restrained. Based on the analysis on areal structure and evolved characteristic, according to the drill hole and mine geological data,the author summarized the development characteristics of geological structures as well as the impaetion on coal bed thickness. It has certain significance to instructing the programming of mining area, the laying out of roadway and working face, as well as the safety production.
