摘要
针对东滩煤矿4303孤岛综放面开采情况,在分析4303孤岛综放面支承压力分布规律的基础上,研究了支承压力在底板中的传递规律。为有效控制跨采巷道附加变形,保证矿井正常生产提供了依据。
Based on the mining condition of No.4403 isolated fully-mechanized mining face with the sublevel caving in Dongtan Coalmine,the transfer of the abutment pressure in the floor is studied. The results provide a basis for controlling additional roadway deformation efficiently and ensure the regular production of the mine.
