充填开采工艺在复杂块段开采的应用

Application of Filling Mining Technology in Complex Block Mining

针对福城煤矿大倾角厚煤层不规则块段开采,传统工艺施工困难,经济不合理,在进行了系统分析与测算基础上,引用了充填开采工艺,集掘进落煤、矸石充填管理顶板为一体。结果表明:充填开采在回收煤炭资源、处置废弃矸石方面具有显著成效,减少了采空区垮落变形对其周围井巷及工作面的影响。

In view of the irregular block mining of thick seam with large inclination in Fucheng Coal Mine,the traditional technology is difficult to construct and the economy is unreasonable.Based on the systematic analysis and calculation,the filling mining technology is quoted,which integrates the management roof of the excavation and coal fall and gangue filling.The results show that the filling mining has remarkable effect in recovering coal resources and disposing waste gangue,which reduces the influence of collapse deformation on the surrounding shaft and working face.
