浅谈巷道掘进超前探测技术的应用
|
摘要
矿井水害是制约煤矿安全高效生产的主要地质灾害之一,对其进行预测和预防有着非常重要的意义。分析了瞬变电磁法、直流电法的技术手段和应用特点,以同煤集团下属某矿井为例,以瞬变电磁法、直流电法同时进行探查作业,并对2种方法得出的数据进行分析。实证结果表明,这2种方法都可以有效判断煤矿井下富水区域位置,数据重合位置相对富水性区域几率较大,为掘进工作提供指导。在应用时,可以利用两者结合的综合物探技术,既提高探测的精度,又通过互相验证提高了探测可靠性。
Mine water hazard is one of the main geological hazards that restrict the safety and efficient production of coal mine. It is very important to predict and prevent mine water hazard. The paper analyzed the technical means and application characteristics of transient electromagnetic method and direct current method. Taking a mine of Datong Coal Group as an example,the transient electromagnetic method and direct current method were used to carry out exploration work simultaneously,and the data obtained by the two methods were analyzed. The results show that the two methods can effectively judge the location of water-rich area in coal mine,and the data overlap position is more likely to be relative to water-rich area,which provides guidance for the excavation work. In the application,the integrated geophysical technology can be used to improve the detection accuracy and improve the detection reliability through mutual verification.
