本文根据鹤壁四矿-250水平运输石门的矿压观测资料,运用岩石力学理论和数理统计的方法,研究了采动对下部(底板)岩巷变形影响的规律;巷道顶板距回采工作面底板的最优垂距;开采影响的极限深度;停采线的合理位置;岩体构造及力学性质对巷道变形的影响;以及回采工作面在回采过程中,临时停采对巷道变形的影响等。文章给出了数据或者公式,可供类似条件下的地面工程借鉴参考。
Based on the observation data of rock pressure in Shimen No. 4 Mine-250 horizontal transport Shimen, the rock mechanics theory and mathematical statistics method were used to study the effect of mining on the deformation of the lower (floor) rock lane; Optimum vertical distance; limit depth of mining influence; reasonable position of stop line; influence of rock structure and mechanical properties on roadway deformation; and influence of temporary stoppage on roadway deformation during stope mining. The article gives data or formulas that can be referenced for ground engineering under similar conditions.
