摘要
司马煤业针对1110放顶煤工作面对应地表存在输电铁塔,采用高水材料局部充填开采工艺,解决了对应地面不用搬迁输电线路铁塔实施连续性开采的技术难题。通过在充填过程中对工作面矿压显现规律的观测分析,地表移动变形以及铁塔的倾斜值、下沉量都满足了《"三下"采煤规程》的要求,为其它矿井解决同类问题提供了借鉴经验。
Sima Mining Company has a transmission tower corresponding to the surface of the 1110 roof coal work surface,and adopts a local filling and mining process of high-water materials to solve the technical difficulties in implementing continuous mining of the tower without relocating the transmission line on the ground. Through the observation and analysis of the law of mineral pressure on the working surface during the filling process,the surface movement deformation,the tilt value and subsidence of the tower all meet the requirements of the ＂ three lower＂ coal mining rules. For other mines to solve similar problems provided a reference experience.
