摘要
通过对巨开元煤业村庄压煤具体情况的分析,提出条带开采和(似)膏体胶结充填法开采两种方案,确保实现地表建筑物的允许下沉变形。条带开采关键是确定开采和留设煤柱参数;膏体胶结充填关键是通过预制膏体砂浆充填,控制采空区顶板下沉离层。两种方案要根据综合经济效益对比选择。
The specific conditions of coal under village in Jukaiyuan coal industry are analyzed, two schemes of strip mining and paste cemented filling mining are put forward, ensures realizing allowed sinking deformation of sur- face building. The key of strip mining is to determine the parameter of mining and unexploited coal pillars, the key of paste cemented filling is to control goal roof sinking by precasting paste mortar filling. One of two schemes is chose ac- cording to comparison of comprehensive economic benefits.
