煤矿水害防治井下物探技术的选择与应用

Selection and Application of Underground Physical Exploration Technology for Coal Mine Water Hazard Prevention and Control

煤矿水害是威胁煤矿安全生产的重大隐患。本文介绍了煤矿水害的类型及成因机理,重点分析了直流电法、瞬变电磁法和瑞利波探测法等井下物探技术在煤矿水害勘探中的基本原理及应用。通过不同物探方法的选择及综合应用,可有效探测含水层、采空区积水、废弃老窑积水分布和导水断层位置等,为煤矿水害防治提供重要的地质依据。但物探技术在实际应用中仍存在一定局限性,需进一步提高探测精度和有效性。

Coal mine water damage is a major hidden danger that threatens the safe production of coal mine.This paper introduces the types and causes of coal mine water hazards,and focuses on analyzing the basic principles and applications of underground physical exploration techniques such as direct current method,transient electromagnetic method and rayleigh wave detection method in the exploration of coal mine water hazards.Through the selection and comprehensive application of different physical exploration methods,the water-bearing layer,water accumulation in the hollow area,water distribution in the abandoned old kiln and the location of water-conducting faults can be effectively detected,which can provide important geological basis for the prevention and control of water hazards in coal mines.However,there are still some limitations in the practical application of physical exploration technology,and it is necessary to further improve the detection accuracy and effectiveness.
