摘　　要：为提高煤矿安全开采的保障能力,研究基于多频无线电坑透技术的煤矿地质综合勘探方法。构建基于“一发双收”的多频无线电坑透方法,采用0.5 MHz与1.5 MHz两种频率,对焦煤公司下属矿井进行煤矿地质综合勘探。经勘探可知,该矿区1101工作面存在3个异常区域,YC1异常区存在煤层裂隙发育与破碎问题,YC2异常区存在旧采空区,YC3异常区存在以往巷采产生的旧采空区,该勘探结果较为精准,未出现遗漏现象;在勘探1131工作面时,发现存在5条地质异常冲刷带,且能有效分析每一冲刷带的严重程度与煤层冲刷情况。该方法可有效实现不同矿区工作面的综合勘探。In order to improve the guarantee ability of coal mine safety mining,a comprehensive geological exploration method for coal mines based on multi-frequency radio pit penetration technology was studied.A multi-frequency radio pit penetration method based on"single transmitter and dual receivers"was constructed,and a comprehensive coal geological exploration was carried out for the subordinate mines of coking coal company with two frequencies of 0.5 MHz and 1.5 MHz.According to the exploration,there are three abnormal areas in the No.1101 working face of this mining area.The problem of coal seam fracture development and fragmentation exists in the abnormal area YC1,the old goaf exists in the abnormal area YC2,and the old goaf produced by previous roadway mining exists in the abnormal area YC3.The exploration results are relatively accurate and no omissions occur.In the exploration of No.1131 working face,it is found that there are 5 geological abnormal scour zones,and the severity of each scour zone and the scour situation of coal seam can be effectively analyzed.Therefore,this method can effectively realize the comprehensive exploration of different working faces in mining areas.
