| Abstract: | At present,the small coal mines have exploited lots of water areas and brought great harm to the safety production of coal mines.We must detect them effectively and timely so as to make appropriate measures and ensure safety production in coal mines.The adoption of the effective exploration methods and the detection of the spatial features of hydrogeological calamity are very important for controlling hydrogeological disaster.In this paper,the principle of the transient electromagnetic method(TEM) was formulated and the single loop setting of TEM was selected.With some engineering examples in some coal mines as examples,the features of the geophysical anomaly of the mined water areas were analyzed,and the effect of the method in detecting the mined water areas was discussed.The results indicate that this method have some advantages such as high resolution,low cost,fastness and accuracy in hydrogeological calamity investigation.It can meet the safety production of the coal mine. |
