新集矿区推覆构造对开采地质条件的影响

Influence of Nappe Structure on Geological Condition of Exploitation in Xinji Mining Area

通过对采、探资料的对比研究,指出了推覆构造在一定程度上影响着煤系断层的展布,砂岩的岩石质量指标与该砂岩距推覆构造底界面的距离呈对数关系,推覆构造不同单元的水文地质条件相差很大,煤层顶板易冒落块体与推覆构造有一定关系,推覆构造对地表沉降具有一定的减缓作用。

Based on comparing mining with exploration information,the distribution of faults of coal measures influenced by nappe structure,the RQD of sandstone related with the distance of sandstone to nappe structure in logarithm,different bydrogeological conditions among the elements of nappe structure,the easy risking mass of seam foof connected with nappe structure are pointed,and all so the reducing of nappe structure on the earth surface subsidence is discussed.
