T-R综合物探技术探测煤矿采空积水区应用研究

为准确定位浅层煤矿中存在的采空积水区,基于现有技术理论提出了一种新型T-R综合物探技术,并依托榆树湾煤矿工程对该技术进行了检验。研究发现:T-R综合物探技术能够综合发挥TEM法和RWP法的优势,且能够实现地下地层可视化;利用该技术精确探测到了榆树湾煤矿内某埋深约150 m的采空积水区的存在,验证了该物探技术的可靠性与适用性。

Application of T-R Comprehensive Geophysical Technology in Detecting Gob Water Accumulation Area of Coal Mine

In order to accurately locate the gob water accumulation area in shallow coal mine,a new T-R comprehensive geophysical prospecting technology is proposed based on the existing technical theory,and the technology is tested by relying on Yushuwan Coal Mine project.The results show that:T-R comprehensive geophysical prospecting technology can give full play to the advantages of TEM and RWP methods,and can realize the visualization of underground strata,using this technology to accurately detect the existence of a goaf water area with a buried depth of about 150 m in Yushuwan Coal Mine,the reliability and applicability of this geophysical prospecting technology are verified.
