目前，许多金属矿山已相继进入深部开采时期，地压问题在矿山开采中也显得愈来愈突出。本文以铁山垅钨矿黄沙北区破坏性地压活动为例，介绍了地压发生前后，地表及井下的一些显现情况，并从开采、采空区处理、地质构造、构造应力场、三角岩柱体稳定性等方面，对地压成因进行了分析论证。 At present, many metal mines have successively entered the deep mining period, and the problem of underground pressure has also become more and more prominent in mining. Taking the destructive ground pressure activities in the north area of ​​Huangsha as an example, this paper introduces the surface and subsurface appearance before and after the occurrence of the earth pressure, and analyzes the characteristics of the ground and underground from the destructive ground pressure activities in the mining, goaf, geological structure, tectonic stress field, Triangular rock pillar stability and so on, the cause of formation pressure was analyzed.
