Abstract: The key point of geological survey of abandoned mine pit and waste rock pile pollution controengineering in Baihe pyrite mine is the survey of waste rock pile and abandoned mine pit. Through survevingand mapping,geophysical prospecting,drilling,test analysis,in-pit survey and other methods to solve theurgent problems of the control engineering and the formation of waste water and filling the drainagechannel.the key to realize comprehensive and accurate geological survey is the pollution control of pyritemine and similar mine environmental problems.
