摘要
采用电阻率层析成像二维测量的方法,对河南省义马市义马煤业(集团)2×50MW跃进电厂采空区和斜风井巷道进行了勘探,获取了采空区、影响区以及斜风井巷道的准确位置。说明,电阻率层析成像二维测量的方法在采空区和斜风井巷道的探测中是行之有效的;煤矿采空区和斜风井巷道内在没有水体存在时,电阻率层析成像二维测量成果图中反映的一般都是高阻异常封闭圈。如果有水体存在,其异常则表现为低阻异常封闭圈。同时,根据该区的地质构造、地层结构、地面建筑等有关参数资料,分析和计算了斜风井巷道的稳定性和安全性。结果表明:主控楼受斜风井巷道的影响较大,是不稳定的,也是不安全的,必须采取妥善的加固措施;主厂房不受斜风井巷道的影响,是稳定的,可以不采取加固措施。
Abstract： The excavated- empty- area and the inclined shaft tunnels were surveyed with 2 - D resistivity tomograpby in YueJin Power plant with 2 × 50MW/year of Yima Coal Mining Industry Group in Henan Province. The places of the excavated - empty - area and the affected range, and the inclined shaft tunnels were determined. 2 - D images of the resistivity tomograpby show generally anomalous high - resistivity closed circles, which suggests that there is no water in the excavated - empty - area and in the inclined shaft tunnels. Should there be water, the anomaly would show low - resistivity closed circles. Moreover the stability and safety of the inclined shaft tunnels are analyzed and calculated based on the parameters of geological structures, stratigrapbic configuration and ground buildings. Our studied results indicate that ①the inclined shaft tunnels have strong influence on the main monitored -control building, and the building is unstable and unsafe and must be reinforced; ②the main workshop does not be affected and is stable.
