摘要:

三山岛金矿邻近渤海,受海水入侵的影响,矿区地下水丰富且水质较差,为保证开采工作的安全进行,需要采用瞬变电磁法对巷道岩体储水分布情况进行探测。介绍了瞬变电磁法的基本原理和工作方法。采用该方法测得三山岛金矿深部巷道岩体富水可能性较强的区域有-765 m中段底板、-780 m中段底板、-780 m中段右帮和-870 m中段底板。采用瞬变电磁法能够准确地定位富水区域,为矿山安全生产提供有效技术依据。

Abstract:

Sanshandao Gold Mine is adjacent to the Bohai Sea.Influenced by seawater intrusion,it has abundant groundwater and poor water quality.In order to ensure the safety of mining workface,it is necessary to use the transient electromagnetic method to detect the distribution of water storage in rock mass of roadways.The basic principle and working mechanism of the transient electromagnetic method were introduced.According to the detection in the deep roadway rock mass in Sanshandao Gold Mine with the method,the probable waterrich areas are the bottom of -765 m level,the bottom of -780 m level,the right side of -780 m level and the bottom of -870 m level.The transient electromagmetic method can accurately locate the water-rich area and provide effective technical basis for mine safety production.
