Abstract: We comprehensively use radio wave perspective with slot wave earthquake in exploration of working face. First, we carry out radio wave perspective exploration for the whole working face and generally circle geologic abnormal body distribution at the working face. Then, we carry out slot wave exploration in key and difficult areas, and explain the geologic abnormal body condition in detail. Through complementary advantages of two methods of geophysical prospecting and contrast checking of results, it ensures the elaborate geological work more accurate and reliable.
