为了排除某矿首采工作面的水害隐患,本文对该矿首采工作面进行矿井瞬变电磁探测,查明上覆煤层采空积水情况、该矿工作面内的钻孔封闭情况和富水情况。通过矿井瞬变电磁法探测,结合钻孔结果分析,验证了瞬变电磁方法的准确性。
In order to exclude the first mining face of a mine hidden water damage, mine TEM is used to de-tect in the coalface during its first operation. We detect the hydrops in overlying layer, the opening of the drilling and the water in the coalface in operation. Through the mine transient electromagnetic method, by combining with drilling results, the accuracy of the transient electromagnetic method is verified.
