南京市岔路口硫铁矿矿区存在为数众多、大小不一、范围不详的采空区,这对工程建设将有隐患。本文利用高密度电法方法探测了该地区采空区的分布范围。探测结果表明该地区第四系松散层电阻率较小,一般不大于10Ω·m,形态近似水平,厚度小于20m,多数在10m以内；三叠系地层电阻率也较小,一般在20~100Ω·m左右,厚度在20-150m左右；三叠系下覆地层为岩浆岩,电阻率一般大于100Ω·m。结合钻孔资料分析可知640/1、710/1、730/1、970/2、840/3、900/4点附近可能为采空区。本次探测成果将为工程建设提供重要的参考资料。

Nanjing fork pyrite mine in number, size, not a range of unknown goaf, which will have a hidden danger to engineering construction. In this paper, the application of high density resistivity method was used to detect the distribution area of goaf. Survey results showed that the Quaternary loose layer resistivity is small, generally less than 10Ω·m, shape approximation level, thickness of less than 20m, most within 10m;Triassic formation resistivity is smaller, generally in the 20 to 100Ω·m, about 20-150m in thickness of strata; Triassic lower as magmatite, resistivity is generally greater than 100Ω·m. Combined with borehole data analysis indicateed that the 640/1, 710/1, 730/1, 970/2, 840/3, 900/4 points may goaf. The detection results will be provided an important reference for the construction of the project.
