摘要
在地质动力的作用下,矿山地下开采正常的岩层与地表移动规律将发生变化,甚至会发生突变灾害。本文基于地球动力区划的理论和方法,对北票台吉矿急倾斜煤层深部开采条件下,煤层地板形变、断层活化、动力突变现象进行了分析研究。提出了区域应力活动是岩层移动变异和地下动力现象的力源,地下采矿活动为地质动力释放提供了空间条件的观点。文中还讨论了矿山地质动力的作用特征、区划方法和对岩层与地表移动的影响规律。
Regularity of rock strata movement will be changed by effect of geodynamic underground mining. Moreover, sometimes breaking ravage will occur. Based on the theory and method of geodynamic division, rock deformation under coal strata and activity of fault as well as sudden change of dynamic has been studied. A view that regional stress activity is a dynamic source of underground dynamic phenomenon and abnormality of rock strata movement and underground mining activity offers the condition of space for releasing geodynamic was presented. Division method and effect rule to strata and surface movement of mine geodynamic was described in this paper.
