洼里煤田地表岩层移动观测成果分析与规律探讨

Analysis and Law Discussion on Observation Result of Surface Stratum Movement in Wali Coalfield

为了掌握软岩矿区采煤引起的地表移动变形规律,按主断面研究法,对龙口矿区洼里煤矿11206地表岩移观测站观测数据进行了分析研究,取得了软岩矿区采煤后地表沉陷移动角、下沉系数、最大拉伸、最大压缩等一些参数和特点,对类似条件矿区保安煤柱留设及建下采煤具有一定参考价值。

In order to grasp the situation of the surface movement and deformation law caused by coal mining in soft rock mining area,using main section study method,the paper analyzed the observation data of the 11206 surface rock movement observation station in Wali Coal Mine of Longkou Mining Area,and got some parameters and characteristics of surface subsidence movement angle,sinking coefficient,maximum tensile and maximum compression after coal mining in soft rock mining area.It has certain reference value for coal pillar setting and mining in similar mining areas.
