根据国家安监总局《煤矿防治水规定》及规程要求,为做好矿井的防治水工作,保障矿井生产安全,切实做到以人为本,安全第一,基本查明井田内水患情况,提出矿井防治水工作建议,为矿井的防治水工作提供基础资料。为此提出并应用了地面物探EH4电磁法查明采空区及其富水性的方法,EH4属于可控源(高频部)与天然场源(低频部分)相结合的一种大地电磁测深系统。
According to the State Administration of Work Safety “Coal Mine Water Control Regulations” and the rules and requirements, in order to do a good job in prevention and control of water mine work to protect the safety of mine production, and earnestly to people-oriented, safety first, the basic identification of wells within the mine flooding, put forward prevention and control mine water Work recommendations for the prevention and control of water in the mine to provide basic information. Therefore, a method of detecting geo-area and its water-richness by geophysical prospecting EH4 electromagnetic method is proposed and applied. EH4 belongs to a combination of controllable source (high frequency part) and natural field source (low frequency part) system.
