摘要
针对蒋庄煤矿31603 工作面底板存在透水隐患的问题,为实现对工作面富水性区域的精确定位,给煤矿防治水工作提供技术支持,采用无线电坑透法和瞬变电磁法的综合物探方法,对研究区域进行探测和研究.研究结果表明:利用无线电坑透法圈定开采区域内隐伏的地质异常区域,预测富水性区域,结合瞬变电磁法分析富水性区域的空间分布和含水层,共同圈定富水性区域,初步确定该工作面存在一处富水性区域,且该区域的含水层主要为十下灰岩含水层.无线电坑透法和瞬变电磁法的联合应用,可以提高对工作面底板透水隐患的探测精度和准确性,为工作面的安全生产提供了可靠依据.
Abstract
In view of the problem of existing water permeation hidden dangers in the floor of the 31603 working face of Jiangzhuang Coal Mine,in order to achieve precise positioning of the water rich area in the working face and provide technical support for water prevention and control work in the coal mine,a comprehensive geophysical exploration method of radio pit permeation method and transient electromagnetic method is adopted to detect and study the research area.The research results indicate that the use of radio pit permeation method to delineate hidden geological anomaly areas within the mining area,predict water rich areas,and combine transient electromagnetic method to analyze the spatial distribution and aquifers of water rich areas to jointly delineate the water rich areas.It is preliminarily determined that there is a water rich area in this working face,and aquifers in this area is mainly the tenlower limestone aquifer.The combined application of radio pit permeation method and transient electromagnetic method can improve the detection precision and accuracy of water permeation hidden dangers in the floor of the working face,providing a reliable basis for safe production of the working face.
