摘要
瞬变电磁探测技术具有反应灵敏、勘探速度快、定位准确的特点,广泛应用于煤矿水害探测。本文以新疆砂墩子煤矿N42采区为例,详细阐述瞬变电磁探测技术在煤层顶底板识别、基岩段富水异常和煤矿采空区积水勘查等方面的应用,并结合地震资料,分析主要断层的含水性和导水性,为煤矿生产提供安全保障。
With the characteristics of sensitive response,fast exploration speed,and accurate determination,the transient electromagnetic detection technology has been widely used in coal mine water hazard detection.Taking N42 mining area of Shadunzi Coal Mine in Xinjiang Province as an example,this paper elaborates the application of transient electromagnetic detection technology in the identification of coal seam top and floor,water-rich anomaly of bedrock section and water exploration of mined-out area.Additionally,the water-bearing property and transmissibility of main faults were analyzed by combining seismic datas,in order to provide geological security for coal mine production.
