摘要
为有效探明采面及上覆煤层的富水情况及地质异常,通过地面物探可从整体上控制区域不同煤层的小煤窑开采积水区和富水区域,井下物探可更有针对性地对比和探明富水异常区,提高构造探测的横、纵向分辨率,最终利用钻孔窥视进行验证,对工作面形成"闭合式"精细化物探,保证采面巷道的合理布置和工作面的安全回采。
To ascertain the water accumulation and geological anomaly in overlying coal seam, downhole geophysical exploration can be more targeted at the abnormal rich water area, to improve the structure detection of horizontal, vertical resolution, and finally use drilling peep for validation, which can form "close type" of fine geophysical exploration of working face, and guarantee the reasonable arrangement and work of the mining face roadway safety mining.
