煤层底板含水层富水性探测研究

Detection Research on Water Abundance of Floor Aquifers

利用矿井瞬变电磁法对某矿1106工作面底板的三灰、五灰含水层进行了探测研究,通过数据处理,形成了含水层二维电阻率剖面图和电阻率切片图。准确圈定出工作面含水层富水区的范围,并对富水性强弱进行了分区。实践表明:矿井瞬变电磁法是一种方便、快捷、高效的探测方法,可以准确地对含水层富水性作出定性评价,对煤矿水害的预防具有重要意义。

In this paper, detection research on the third limestone and the fifth limestone aquifers in 1106 working face floor in a mine was conducted by using the mine transient electromagnetic method. Through data processing, the two-dimensional resistivity profile and resistivity section diagram of the floor aquifers were formed. The water abundance area of the aquifers in the working face was accurately determined and the weakness and strength of water abundance of the floor aquifers were distinguished. Practice showed that the mine transient electromagnetic method is a convenient, fast, and efficient detection method, and with this method the qualitative evaluation on the water abundance of the aquifers can be accurately made, so it is of great significance for the prevention of coal mine water disaster.
