摘要
准确评价回采工作面富水性对工作面安全回采具有重要的意义。针对张家峁矿井14210工作面含水条件复杂的情况,本次物探工程综合使用矿井瞬变电磁法和音频电穿透技术对该工作面顶板富水性探测,并采用基于阻尼最小二乘的瞬变电磁反演方法和基于改进的RESINVM3D音频电穿透反演方法对2种物探方法进行三维反演成像显示,共划定5个富水异常区域。通过收集探放水资料验证,本次综合使用2种物探方法进行顶板富水区探测取得了良好的效果。在物探划定异常区域内钻孔出水量相对较大,在物探无异常区域内钻孔无较大出水情况。本次物探得出的结论取得了良好的效果对实际的探放水工作有很大的指导意义。
How to accurately evaluate the water content of the mining face is of great significance to the safe recovery of the working face.In view of the complicated water-bearing conditions of the 14210 working face,this geophysical exploration project uses the underground TEM and the audio electric penetration technology to detect the water yield property of the working face,and uses the transient electromagnetic inversion method based on the damping least square and the audio frequency electric penetration inversion method based on the improved RESINVM3 D to perform the inversion 3 D imaging display of the two geophysical exploration methods 5 water rich abnormal areas are demarcated.Through the collection of water exploration and discharge data verification,the comprehensive use of two geophysical prospecting methods to detect the roof rich water area has achieved good results.The water yield of borehole is relatively large in the abnormal area delimited by geophysical exploration,while the water yield of borehole is not large in the area without abnormal geophysical exploration.The conclusion of this geophysical exploration has obtained a good effect,which is of great guiding significance to the actual water exploration and discharge.
