摘要
为使巷道设计、支护计算和稳定性分析更加科学、可靠和经济,了解和研究地应力的大小、方向及其分布规律,提出地应力与巷道支护关系就尤为重要。文中详细介绍了平顶山八矿的地应力计算原理,并根据矿区实测地应力资料,得出了计算区域初始地应力场相应的应力回归公式,并且分析了矿井地应力的分布特征。
To make tunnel design, calculation of supporting and analysis of stability more scientific, reliable and economic, research of the in-situ stress state, direction and distribution is particularly important. This paper introduces the in-situ stress measurement principle of the eighth mine of Pingdingshan coal mining cooperation. Based on the determined in-situ stresses, their distribution characteristics are obtained by using theoretical and statistical analyses. The relationship between in-situ stress and geological tectonism is studied and some meaningful conclusions are obtained.
