【摘要】 矿井巷道掘进前方地质条件预测是一项重要工作,钻探和物探方法及其综合运用是目前超前探测的常用方法。以巷道掘进工作面电磁法超前探测技术为主,对直流电法及瞬变电磁探查方法原理、技术装备改进和地质解释等方面所获得的进展进行了阐述,其目标是提高单一方法技术对低电阻率异常的分辨能力,并分析了电磁超前探测技术使用中存在的问题。结合方法技术、仪器设备、资料解释及定量评价等方面,提出了今后煤矿井下电磁法综合超前探测技术发展的认识和思考。由单一方法探测到多参数监测,由综合解释到多场数据联合反演,由定性到定量地质解释,不断提高探查的准确率是未来技术发展的方向。更多还原

【Abstract】 Forecasting geology conditions of laneway ahead is a key work in mine production. Now the drilling and geophysics methods,as well as comprehensive application,are the common methods to do advanced detection during the driving period. In the article,taking the advanced detection technology by electromagnetic method in the driving working face of mine as the principal thing,the obtaining progress of direct current electric method and transient electromagnetic method is elaborated about the method principle,improvement of technical equipment,and geological interpretation,and so on. And the existing related issues for application of the electromagnetism advanced detection technology are analyzed. Combining with method and technique,instrument and equipment,data interpretation and quantitative evaluation,the understanding and thought for the future development of electromagnetic integration method and technology in mine are proposed technically. From single method detection to multi-parameter monitor,from comprehensive interpretation to joint inversion with multi-field data,from qualitative to quantitative geological interpretation,and to improve continually the exploring precision of advanced detection are the technique developing direction in the future.更多还原
