压覆矿产资源储量估算中保护煤柱边界的确定

Determination of the protective coal pillar in pressed mineral resources estimation

根据《建筑物、水体、铁路及主要井巷煤柱留设与压煤开采规程》(煤行管字【2000】第81号)文要求,利用相关地质勘查资料,对110 k V石岩湾变电站建设用地范围压覆矿产资源储量进行核实,确定了变电站保护煤柱、维护带的宽度,提出了在此保护煤柱范围内不能采煤的建议。

Based on the requirements of ＂ coal pillar preserve of buildings,water,railway and main roadways and mining regulation＂ and relevant geological exploration data,the pressed mineral resources under Shiyanwan 110 k V substation is checked,the parameters of protective coal pillar for substation is determined and the suggestion that the mining can＇t be carried out in the range of coal pillar is proposed.
