摘　　要：分析了物探、钻探、化探3种井下探测手段对掘进巷道中煤矿小窑采空积水区有效探测的可行性及实用性。通过在柳湾煤矿西翼胶带巷巷道P51点东51处进行物探工作,工作结束后根据物探结果设计钻孔并进行钻探探放水,之后采用化探技术手段分析水质类型并分析水源,通过分析与总结物探、钻探、化探工作对小煤矿采空积水区探查中发挥的作用,证明了井下多种探查手段综合应用的合理性和有效性。在井下防治小煤矿采空积水区时,该矿采用物探先行、钻探验证、化探跟进的工作方法,并将物探、钻探、化探测工作严格执行到位,相较之前的采用单一技术手段,掘进巷道中小煤矿采空积水区的防治效果得到了明显提升。In this paper,the feasibility and practicability of the three underground detection methods of geophysical,drilling and chemical exploration were analyzed to effectively detect the mined water area of the small kiln of the coal mine in the driving tunnel.Through the geophysical exploration work in the East 51 of P51 point in the West Wing belt roadway of Liuwan Coal Mine,after the completion of the work,according to the results of the geophysical exploration,the drilling hole was designed and the water was explored.After that,the geochemical exploration technology was used to analyze the water quality type and analyze the water source.Through the analysis and summary of the role of geophysical exploration,drilling and geochemical exploration in the exploration of goaf ponding area in small coal mines,the rationality and effectiveness of comprehensive application of various downhole exploration methods were proved.In the underground prevention and control of gob water accumulation area in small coal mines,geophysical exploration first,drilling verification and geochemical exploration follow-up are adopted in the mine,and the geophysical,drilling and chemical detection work is strictly implemented in place.Compared with the previous single technical means,the prevention and control effect of gob water accumulation area in small and medium-sized coal mines in driving roadway has been significantly improved.
