基于因民铜矿隐伏采空区的高密度电阻率法及EH-4探测技术研究

Research on High Density Resistivity Method and EH-4 Detection Technology Based on Concealed Goafs in Yinmin Copper Mine

在因民铜矿的地表形貌特征及查明深部采空区的基础上,结合采空区地球物理探测方法,采用高密度电阻率法及EH-4对因民铜矿大劈槽矿段的隐伏采空区开展物探工作。数据解译显示,高密度电阻率法探测浅部空区成果与实际情况的匹配度高,可圈定采空区的空间形态;EH-4可探测空区的空间位置,有效深度可达1000m,但是无法进一步测出空区的形态;对两种探测成果进行相互对比分析,取长补短,有效地提高采空区探测成果准确性和可靠性,为今后在采空区探测方面研究提供了技术支撑。

Based on the surface topography of the Yinmin copper mine and the identification of the deep goaf,combined with the geophysical exploration method of the goaf,the high-density resistivity method and EH-4 are used to make the large copper trough of the Yinmin copper mine.The geophysical work was carried out in the hidden goaf of the mining section.The data interpretation shows that the high-density resistivity method detects the shallow space and the actual situation is highly matched,and can determine the spatial shape of the goaf;EH-4 can detect the spatial position of the empty area,and the effective depth can reach 1 000 m.However,it is impossible to further measure the shape of the empty area;compare and analyze the two detection results,and learn from each other to effectively improve the accuracy and reliability of the detection results in the goaf,which can provide technical support for future research on the detection of goaf.
