地下磁流体探测方法在煤矿水害隐患探测中的应用

煤矿水害是我国煤矿频发且较严重的事故之一，预先探明煤矿矿区水体分布及其水量是防止和避免煤矿水害事故发生的有效方法．地下水（煤矿水害事故的主体）是良导体，其流动时受到天然电磁场的作用会产生相应的特征信息，采用磁流体探测仪接收并提取该特征信息，能比较准确地对地下水的位置分布及水流的瞬时流量进行预测．阐述了地下磁流体探测方法的基本原理和工作方法，并在四川仁寿县汪洋煤矿进行了水害隐患探测验证，探明了该煤矿指定区域内的地下水体分布，准确地找出了主水仓的位置，探测结果与实际相符．

Application of underground magneto fluid detection method in hidden water disaster in coal mine

Coal mine water disaster is a frequent occurrence and one of the most serious accidents of coal mine in China. To find out the water distribution in coal mining area and its water prior is an effective method to prevent and avoid accidents of coal mine water disaster from occurring. Groundwater （subject of accidents of coal mine water disaster） is one kind of good conductor, it will be affected by the natural electromagnetic field while it is flowing and generate characteristic information. Using magneto fluid detector receives and extracts the information can accurately position the groundwater distribution and predict the instantaneous flow of water. In this paper, the basic principles and work methods of the underground fluid detection method are the method in Wangyang Coal Mine at Renshou County, underground water in the given area is found out, including expounded, and it also gives an example of application of Sichuan Province. The result that the distribution of the a water storage.
