吕沟煤矿村庄下采煤采动影响预计及评价分析

Mining Influence Forecast and Evaluation Analysis on Coal Mining Under Village in Lügou Coal Mine

吕沟煤矿九区段-245 m水平以下村庄压煤较多,为了合理解决村庄下采煤问题,根据矿井的地质条件等因素,利用概率积分法对利用顺序开采和跳采方法时地表下沉值和水平变形值等参数进行预计,对比分析2种开采方案开采对村庄的影响和危害程度后,确定了村庄下开采方案,并提出注意事项。

Large amount of coal is buried under village on-245 m level in the ninth section of Lügou Coal Mine.To solve the problems of mining coal buried under village reasonably,according to the geological conditions and other factors,surface subsidence value and horizontal deformation parameters were respectively obtained by sequence mining and jump mining,then the above data were forecasted using probability integral method.Comparison of influences and damage degree to village after mining was made between two mining schemes.Based on this,scheme of mining under villages was determined,some matters needed to be paid attention to were also put forward.
