摘要
通过前人工作实践,总结了煤矿采空区的部分地球物理特征.对营城煤矿未知采空区选择采用了高密度电阻率法、瞬变电磁法及放射性土壤测氡方法进行两个剖面的综合探查,得出该煤矿采空区及塌陷区为低电阻率、高氡浓度异常特征.
Summarized the geophysical characteristics of exhausted area based on the former information of practices; and selected the HD （high density） resistivity method, TEM （Transient Electromagnetism） method and soil radon radioactive measurement method to make our measurement. Based on the two survey profiles in unknown exhausted area in Yingcheng, the results show that the geophysical characteristics of the exhausted area and sinking area are low resistivity and high radon concentration.
