摘要
为查明将军戈壁二号露天矿东北角烧变岩区水文地质情况,采用磁法、瞬变电磁法及钻孔补勘等工作方法探测了煤层火烧区岩区富水性。结合物探地质资料、钻探、地质地形地质资料,对测区内磁异常及低阻异常进行了综合分析,确定了烧变岩边界区域,富水区的分布范围、火烧区的含水层信息。采用多种方法探测,从多维角度分析火烧区空间形态和水文地质特性及火烧区与原岩水层之间的水力联系,评价富水区突水性,综合保障确定了矿区采煤防突水安全工作。
In order to find out the hydrogeological conditions of the burned rock area in the open-pit mine,the magnetic method and the transient electromagnetic method are used to detect the water-rich water content in the coal-fired area of the coal seam,and the geological data such as the borehole and the relevant maps of the coal seams are used to detect the magnetic anomalies in the survey area.The low-resistance anomaly is comprehensively analyzed to determine the distribution range of the burnt rock boundary and the water-rich zone;drilling to carry out hydrogeological tests,to find the aquifer depth,thickness,lithology and head pressure,and to identify between the aquifers The hydraulic connection determines the water-rich aquifer and various hydrogeological parameters and evaluates the water inrush in the water-rich zone,which ensure safe work of inrush in mine area.
