摘 要：本文利用高密度电法对煤矿采空区进行现场测量，在测量区域内布设9条测线并使用DUK2A高密度测量系统进行测量，（其中GMD09作为背景参照值设置在未注浆区域内）。测得数据后运用Geogiga Rimager軟件进行处理取得视电阻率等值线，运用所学物探及相关地质知识和已知资料取得9幅成果图并对其中2幅具低电阻异常特点的成果图进行分析评价，最后得出测线注浆区域视电阻率值比未注浆区域高，注浆效果整体较好的结论。

Abstract：The high density electrical method is used to measure the coal mine goaf，and 9 lines are set up in the measuring area and the DUK2A high density measurement system is used.（in which GMD09 is set in the non grouting area as the background reference value）.After the data were measured，the apparent resistivity contour was obtained by Geogiga Rimager software，and 9 results were obtained by using the geophysical and related geological knowledge and the known data，and the results were analyzed and evaluated.Finally，the apparent resistivity value of the line grouting area was higher than that of the non grouting area and the conclusion is that the effect of grouting is better.

1 采空区概况

采空区所在地为乌鲁木齐市米东区铁厂沟八一煤矿低山丘陵区域内，[12]总体地势为南高北低，部分地区可见明显塌陷，局部回填。地层主要为第四系黄土盖层、侏罗系风化基岩和煤层。由于煤矿停采，井内水位不断上升致使采空区越加不稳定。

2 本区域的高密度电法勘察

自然界中存在的岩土体，因其各项因素如岩土类别、岩土体成分及结构、自然温度及湿度等的不同，故表现出不同的电学性质。高密度电法以这种电学性质差异为基础，通过使用仪器观测地质体表现出的电性差异及电场变化并解决某类地质问题。高密度电法勘察主要是通过不同或同一岩层因成分和机构等因素的不同而具有的不同的电阻率这一性质，使用接地电极将直流电导入地下从而建立起稳定的人工电场，然后通过于地表观测到的某点垂直方向或某剖面的水平方向的电阻率变化，继而了解岩层的分布或地质构造特点。……
