摘要
井下矸石直接用于充填置换“三下”压煤,是绿色开采体系中的重要内容。阐述了李村巷道矸石充填开采的基本思路与工艺路线,对影响采出率的因素进行分析。利用地表沉陷预计理论,通过与在同类地质条件下非充填开采相对比,巷道矸石充填法开采对于地表变形的控制有显著效果。
It is an important part of the green mining system to use underground gangue directly for filling and replacing"three-under"compressed coal.This paper described the basic ideas and technological routes of the gangue filling and mining in road-ways of Licun Coal Mine,and analyzed the factors affecting the recovery rate.Using the prediction theory of surface subsidence,and comparing with the non-filling mining under similar geological conditions,it is obtained that the mining of roadway gangue filling method has a significant effect on the control of surface deformation.
