瞬变电磁物理勘探法在煤矿采空区水害隐患治理中的研究与应用

Research and application of transient electromagnetic exploration method in hidden water dangers of coal mine goaf

为解除煤矿采空区水害通过导水通道对工作面安全开采的重大隐患,减少矿井水害灾难和经济损失,根据现场条件,采用瞬变电磁物理勘探法,对河南能源新疆公司龟兹矿业西井东北部开采初期采空区范围及积水进行探测,运用三维切片技术对瞬变电磁法探测数据进行分析,对采空区积水的水力特征做出评价,为下一步水害综合治理提供可靠依据。

In order to solve the major hidden dangers of safe mining work face derived from water channel in the coal mine goaf,reduce the mine water disaster and economic loss,the transient electromagnetic physics exploration method was studied according to the site conditions of the northeastern part of the Henan Energy Xinjiang Company.In the initial stage of mining,three-dimensional slicing technique was used to analyze the data of the transient electromagnetic method in the detected the area of the goaf with accumulated water,could evaluates the hydraulic characteristics of water in the goaf,thus provides a reliable basis for the next comprehensive treatment of water damage.
