地应力是引起各种岩土工程变形和破坏的根本作用力, 是确定工程岩体力学属性,进行围岩力学定性分析, 实现岩土工程设计和施工科学化的必要前提。在我国采矿领域, 传统的采掘和施工多数是根据经验进行, 一直没有对地应力进行系统的研究。鉴于此, 从矿井地应力实测方法、地应力分布特点及地应力对采矿的影响等方面进行了系统的分析和研究。
Geo-stress is the fundamental force that causes deformation and damage of all kinds of geotechnical engineering. It is the necessary prerequisite to determine the mechanical properties of engineering rock mass, carry out the qualitative analysis of surrounding rock mechanics, and realize the scientific design and construction of geotechnical engineering. In the field of mining in our country, most of the traditional excavation and construction are based on experience, and there has been no systematic study of the earth stress. In view of this, we systematically analyze and study the methods of in-situ stress measurement in mine, the distribution of geostress and the influence of geostress on mining.
