摘要
为了探明乌鲁木齐及周边地下陡倾煤层采空区的分布范围和埋深,应用高密度电阻率法进行探测。根据视电阻率二维反演断面图,分析电阻率异常形态、高低阻分布等特征,推断出采空塌陷区和安全边界。经钻探验证,推断结果与实际情况相吻合,高密度电阻率法是准确探测陡倾煤层采空区空间形态特征及其塌陷影响区边界范围的有效方法。
In order to explore the distribution range and burial depth of goaf in Urumqi and its sur⁃rounding underground steep coal seam,the high-density resistivity method used for detection.According to the two-dimensional inversion section of apparent resistivity,the abnormal shape of resistivity and the dis⁃tribution of high and low resistivity are analyzed,and the mining subsidence area and safety boundary are deduced.The drilling verification shows that the inference results are consistent with the actual situation,and the high-density resistivity method is an effective method for accurately detecting the spatial morpho⁃logical characteristics of the goaf in steep coal seam and the boundary range of the collapse-affected zone.
