TEM在煤矿采空区注浆效果检测中的应用研究

某地需在老旧采空区范围内建造储存仓库，现已对建筑范围内采空区注浆，为探测采空区注浆效果保障建筑安全，根据现场环境，通过对比分析多种物探方法，决定采用TEM方法对注浆区域进行检测。经现场试验，取得适合该区的施工参数并严格按照施工参数施工。经后期室内数据分析处理，得到该区域视电阻率剖面及-60 m等深切片成果，将检测成果与注浆资料和采空区矿井资料相结合，对比分析勘探成果与已知采空区空间位置信息，结果表明采空区域视电阻率等值线平滑，没有明显的波动现象，说明采空区注浆效果良好。研究结果表明，采用TEM可以较好地检测采空区的注浆效果，为以后采空区注浆治理效果检测等提供了一种较好的检测方法。

Application research on TEM in grouting effect detection in goaf of coal mine

A storage warehouse needs to be built in the old goaf area in a certain area.Now，the goaf area within the building area has been grouted.In order to detect the grouting effect in the goaf area and ensure the building safety，according to the site environment，by comparing and analyzing various geophysical exploration methods，it is decided to use TEM method to detect the grouting area.The construction parameters suitable for this area are obtained through field test and the construction is carried out in strict accordance with the construction parameters.After indoor data analysis and processing in the later stage，the apparent resistivity profile and -60 m depth slice results in this area are obtained.The detection results are combined with grouting data and goaf mine data，and the exploration results are compared with the known spatial location information of the goaf.The results show that the contour of the apparent resistivity in the goaf is smooth and there is no obvious fluctuation，indicating that the goaf grouting effect is good and good detection effect is achieved.The results show that TEM has a good effect on the detection of grouting effect in goaf，which provides a good detection method for the detection of grouting treatment effect in goaf in the future.
