硫磺沟煤矿原岩应力实测与分布规律研究

In-situ stress measurement and the research of the distribution laws of Liuhuanggou coal mine

硫磺沟煤矿采用应力解除法进行了5个原岩应力测量,通过对原岩应力量值、方位、倾角、埋深等因素的综合分析对比,得出矿井地应力分布规律和特点,为矿井巷道布置、支护设计和动力灾害防治提供了科学依据。

Using stress relief method, in this paper, chose ifve points to measure the original rock stress, through comprehensive analysis and comparison of In-situ stress value, range, dip angle, depth and other factors, concluded that the law of stress distribution and characteristics of mine, provided a scientiifc basis for the mine roadway layout, support design and aerodynamic force disaster prevention and control.
