| A comprehensive methods in exploration hydrogeological condition of limestone has been proposed after analyzing the currently techniques. It consist of Transient Electromagnetic Method(TEM), areal hydrogeology survey, drilling,groundwater observation and monitor, chemical test, pumping and injection test. This time, we have done the work bellow: A and B area TEM survey, 0.746km2 and 1.006km2,together 1.752km2; drilling holes 4 on the ground and 3 down the mines, are 2741.40m;radioactivity logging is 1866m; 9 water samples have been tested; 26 rock samples have been tested; 2 single pumping tests,1 single injection test, and 1 outflow test; groundwater observations from some holes for a long time. Through all the work, we have got some new views of groundwater condition,and analyzing it’s threaten with harm to coal mine. We have proposed some ways of avoiding and controlling groundwaterhazard. It’s worthy of popularizing this comprehensive methods. |
