摘要
为了防止煤与瓦斯突出矿井的危害,保证煤矿的安全生产,宏远煤业采用"二物探"、"一长探"、"一短探"、"一对照"的综合探测方法,有效的控制了底板岩巷的煤隔层厚度,同时保证了各大巷坡度使用要求,在实践工作中效果良好。
To protect against outburst of coal and gas in mines and to guarantee the safe production,Hongyuan Mine adopts an integrated exploration method, including two-geophysical-prospecting,one-long-prospecting, one-short-prospecting and one-comparison. The thickness of coal interlayer of floor rock was effectively controlled and the operating requirement of main roadways’ slope was ensured,which showed better effects in practice.
