摘要
以和善矿6-1采区6102、6103工作面为例,采用瞬变电磁法对回采工作面上层采空区进行探测,通过数据采集、资料解释,绘制视电阻率剖面、切片图,圈定上层采空区的范围和位置,估算出采空区积水量。实际应用表明,矿井瞬变电磁法针对矿井工作面上层采空区积水可实现全方位的预测预报,能够有效确定煤层顶板采空区积水的位置、范围、水量,同时有效验证疏水效果,为矿井安全生产提供指导。
Taking 6102 and 6103 in 6-1 mining area of Heshan coal mine as an example,the transient electromagnetic method is used to detect the upper goaf of the working face,through data collection and data interpretation,the visual resistivity profile and slice chart are drawn,the scope and location of upper goaf are delineated,and the water accumulated in goaf is estimated.The practical application shows that the transient electromagnetic method can be used to realize the omni-directional prediction and prediction of the water in the Upper goaf of the mine working face,it can effectively determine the location,scope and quantity of water in goaf of coal seam roof,and validate the drainage effect,which can provide guidance for mine safety production.
