摘　　要：为了预测平煤一矿丁6煤层冲击倾向性,在该矿三水平对垂深800 m及其以下煤层取样进行冲击倾向性测定,利用RMT-150B型岩石力学伺服控制系统进行了弹性应变能指数WT、冲击应变能KN、动态破坏时间DT等3项指标检测,结果表明,丁组煤样属于弱中等冲击危险层,结合三水平丁6煤层结构分析,认为三水平丁6煤层无冲击危险性。In order to predict the coal seam pressure bump probability in Ding6 coal seam in the Mine,coal samples are taken from the #3 level at-800m and deeper coal seams for pressure bump probability analysis.In doing so,RMT-150B rock mechanics servo control system is used in the testing for 3 indices such as medium elasticity strain energy index WT,bump strain energy KN and dynamic destruction time DT,etc.The results show that coal samples taken in the Ding Group fall into the category of medium-weak probability of pressure bump dangers.When combined with the coal seam structure analysis of Ding6 coal seam at the third level,it is taken for granted that Ding6 coal seam at the third level is not subject to the danger of pressure bump.
