摘要:

为解决图古日格金矿由于矿脉分布复杂、地质构造多样导致的采场矿压剧烈、矿脉方向杂乱等问题,使用空心包体式三轴应变计,采用钻孔应力解除法对图古日格金矿6个测点进行了系统地地应力现场实测。测量结果表明:井下为典型的构造应力场类型,最大水平主应力方向为近NE,与地质构造挤压运动的结果吻合,属于中等应力值区域,矿脉方向与最大主应力方向近垂直。地应力分布特征为该矿生产设计与矿压控制工作提供参考,为找矿方向提供初步判断。

Abstract:

In order to solve the fierce pressure and ore vein direction disorder problems cause by complexity distribution of vein gold and diversity of geological structure,stress measurements of six points is conducted in Tugurige gold ore by means of hollow package postures triaxial strain gauge using borehole stress relief method systematically.The stress measurement data shows that Tugurige gold mine belongs to typical tectonic stress field and the orientations of maximum horizontal principal stress is near to NE,it fit to the geological tectonic compressional movement.The magnitudes of the stresses are medium values.The results also show that the ore vein and the maximum principal stress is approximately vertical.In-situ stress distribution characteristics can give reference for the mine production design and the underground pressure control,provides a preliminary judgment for prospecting direction.

Key words: mine survey, stress law releasing method, in-situ stress measurement, ore vein direction, prospect
