瞬变电磁法快速探查煤矿突水构造关键技术及应用效果

受地形和地质条件的影响，快速探查积水老窑突水淹井通道、探查淹井突水小构造等是煤矿水文物探研究的难点。通过研究TEM在煤矿水文地质勘探中的关键技术问题，充分利用TEM的对低阻敏感、横向分辨率高、速度快等特点，应用新的反演技术提高TEM的准确度，在多次煤矿突水淹井抢险救援(灾)中，快速准确地完成了煤矿突水构造的定位探测，为煤矿抢险救灾赢得了时间，社会效益和经济效益明显。 

The key technology and application effects of transient electromagnetic method for rapid delecting water inrush structure in coal mine

It is a difficult for hydrological geophysics to rapidly and accurately detect the waten channels and small water inrush structures because of the influence of geological and topographical conditions. Through the study of the key technical problems in TEM for hydrogeological exploration in coal mines, the features of sensibility to low resistivity, high horizontal resolution and rapidity of TEM were sufficiently used. New inversion technology was adopted to enhance REM accuracy. Positioning detection of water inrushing structures was rapidly and accurately performed in many rescues during water inrush and flooding in coal mines. The social and economic benefits are obvious.
