为了查明汾源煤业文明矿5-101首采工作面底板岩层赋水情况和煤层地质异常体情况，并对其进行突水危险性区域划分及评价，采用瞬变电磁法、直流电法和无线电波透视法三种物探方法综合勘探，综合分析三种物探方法探查结果，并结合揭露情况和钻孔验证。结果表明：位于切眼往外（0~250）m范围内，工作面底板相对破碎、裂隙岩溶发育或富水性强，导高大，且煤层内部较不均匀，存在多条5m以上落差含水断裂破碎带，此区域突水危险性最大；切眼往外（300~380） m范围内存在局部富水区域，导高较小，但不存在构造破碎带，突水可能性较小；工作面其他区域都较安全。综合物探比单一物探更具有准确性和可靠性，更符合工程实际情况，为采取针对性的治理措施从而实现安全回采提供了参考依据。

o identify the water content situation of rock and the circumstances of coal geological anomalies in floor of 5-101 first mining face in Fenyuan Civilization coal mine,and carry out classification and evaluation on the dan-ger zone of water inrush,three kinds of geophysical methods,including the transient electromagnetic method,DC law method and radio wave perspective method,were used to conduct comprehensive exploration. The results of three kinds of geophysical exploration methods were comprehensively analyzed and verified combining with disclo-sure situation and drilling. The results showed that within the range of 0-250m of cut out,the mining face floor is relatively broken,with development of fractured karst or high water abundance and big raising height,in addition the seams inside is less uneven and exists multi water bearing fracture zones with above 5m drop,and this area has the greatest risk of water inrush. Within the range of 300-380m of cut out,there exists partial water-rich region and has minor raising height,but there is not structure fracture zone,so it has minor possibility of water inrush. The rest regions of face floor are safer. The integrated geophysical explosion is more accurate,reliable and better com-pliance with practical engineering than single geophysical explosion,which provides a reference for taking appropri-ate control measures to achieve safe mining.
