矸石混凝土间隔充填采煤方法研究

Study of mining method of gangue concrete interval filling

随着煤炭资源在王庄矿区日益枯竭,对"三下"压煤的回收势在必行。本文根据王庄矿煤层赋存条件和当地充填材料的来源,经研究决定在旺格维利采煤方法的基础上进行矸石混凝土间隔充填技术控制地面的下沉,为以后"三下"压煤的回收提供借鉴。

With the increasing depletion of coal resources in Wang Zhuang mine,recovery of the ' three unders ' coal is imperative. In this paper,according to the Wang Zhuang mine coal seam conditions and local material sources,after researched,be based on Wongawilli mining method,using gangue concrete interval filling technology to control the ground subsidence,for the recovery of'three unders'coal offer reference.
