矿井直流电法在永定矿区水害防治中的应用

Application of Mine DC Method to Prevent and Control of Water Disasters in Yongding Mining Area

矿井水害已成为福建煤矿五类灾害中对安全生产构成最大威胁的灾害,而永定矿区是福建省水害较严重的地区之一。为了查明该区水害(断裂水、老空水)的具体分布范围,在对物性基础分析的基础上,开展了矿井直流电法的超前勘探。结果表明,直流电法在探测煤矿巷道前方含水异常体位置具有较好的效果。其结果可为井下水害预报及防治提供参考依据,为煤矿安全开采提供地质保障,也可为福建其他煤矿类似水害探测及分析提供借鉴。

Mine water disaster has become the biggest threat to safety production in the five kinds of coal mine disasters, and Yongding mining area is one of the more serious water disaster areas in Fujian Province. In order to find out the specific distribution of the water disasters（fracture water, goaf water） in the area, advanced detection of mine DC method is carried out, on the basis of analysis of the physical basis. Results show that the direct current method in detecting coal mine roadway ahead aqueous abnormal body position has a good effect. The detection results can provide reference for mine water disasters forecasting and prevention, for coal mine safety mining geological safeguard, and also for similar small coal mine water disasters detection and analysis in the future in Fujian.
