摘　　要：针对同煤集团部分矿井采掘工作面回采及掘进前面临的小窑空巷问题,从煤矿防治水实际工作出发,在全面分析小窑空巷空间分布的基础上,采用井下直流电法三极超前探、四极测深等不同施工方法,研究各种施工方法对小窑空巷的电性特征,总结一套有效的施工技术方法。In view of the problems of small kiln and empty alley before mining and driving in some mines of Tongmei group,starting from the actual work of water prevention and control in coal mine,on the basis of comprehensive analysis of spatial distribution of small kiln and empty alley,different construction methods such as underground direct current three pole advanced exploration and four pole depth sounding are used to study the electrical characteristics on small kiln and empty alley,and a set of effective construction technology methods are summarized.

关 键 词：小窑空巷 四极测深 三极超前探 有效性
