巷道矸石充填技术在邢东矿的应用

Application of roadway gangue filling technology in Xingdong Mine

为解放“三下”呆滞煤炭资源,在邢东矿1100南部采区进行巷道矸石充填研究。研究表明,采用间隔跳采的方式可以回收煤炭资源。由于对巷道充填,可适当降低巷道的支护强度。地面沉降观测表明,地表变形值较小,建筑物变形在Ⅰ级以内,巷道矸石充填取得了较好的经济和社会效益,为类似条件下的煤炭资源回收提供了参考。

In order to free the mining under water,building and roadway,a study on roadway gangue filling was conducted in the 1100 south mining area of Xingdong Mine.The study showed that coal resources can be recovered by using interval jump mining.Due to the filling of the roadway,the support strength of the roadway can be properly reduced.The ground settlement observation showed that the surface deformation value was small,and the building deformation was within class I.The roadway gangue filling achieved good economic and social benefits,which provided a reference for coal resource recovery under similar conditions.
