煤层构造破碎度及其在水文地质中的应用

THE STRUCTURE-BROKEN DEGREE OF COAL SEAM AND ITS APPLICATION ON HYDROGEOLOGY

断块构造区域内煤层及其周围岩层在构造应力作用下的形变具有很好的协调性和密切的相关性。利用煤层构造破碎度,能预测底板隔水层的构造破坏程度。经过几年的现场试验研究,证明该方法简便,结果直观。

Under the tectonic stress,the deformations of coal seams and the adjoining rock strata infault-block structural area are of good coordination and close correlation.Using the method of structure-broken degree of coal seam,the structure-destroyed level of the water-resisting floor of coal seam can bepredicated.After several years' experiments,it is proved that above method is easy to use and of audio-visualresults.
