摘要
在煤矿开采中,探明矿井水异常区的范围对于煤矿防治水十分重要。为了提高煤矿探放水的效果,需首先采用物探方法探明矿井异常区域的分布情况,然后再采用定向钻探技术探明异常区的水文情况。碾焉煤矿8102综采工作面现场应用结果表明,采用定向钻探技术极大地减少了施工量,提高了防治水的有效性。
In coal mining,it is very important to explore the abnormal area of mine water for coal mine water control.In order to improve the effect of water exploration and drainage in coal mines,it is necessary to explore the distribution of mine abnormal areas by geophysical exploration method first,and then to explore the hydrology of abnormal areas by directional drilling technology.The field application results of 8102 fully mechanized mining face in Nianyan Coal Mine show that the directional drilling technology greatly reduces the construction amount and improves the effectiveness of water control.
