求翻译：滑褶造成的对煤层穿刺应属于层间滑动构造作用伴生的构造类型，当包括煤层顶底板在内的岩层遭受层间剪切作用时．由于岩体质量不均一性或早期裂隙面的存在等因素在局部产生不协调褶皱。又因煤层较其它岩层软弱而易成为褶皱穿刺层位，随着层问剪切作用的加强，小褶皱轴面倾角度变小而使顶(底)板岩层不断进入煤层。尤其是在顶尤其是在顶(底)板岩层薄而脆弱的条件是什么意思？

Slip folds caused by the seam puncture are associated with the structure of the layer between the sliding tectonic types, including coal seams, including the rock subjected to interlaminar shear. The uncoordinated fold due to the uneven quality of rock mass or early fracture surfaces of the existenc
