摘要

原始地应力是地下工程围岩稳定与支护结构设计的一个基本参数。在唐口煤矿井下回风石门、西翼辅助运输石门等不同构造部位的3个测点采用空心包体应力解除法进行了现场地应力的实测工作，测点的埋深达1 024～1 030 m。详细介绍了三维地应力及其主应力的计算原理，并根据矿区实测地应力资料，分析了矿井地应力大小、方向变化和分布特征，进而获得了该矿区地应力的定性及定量资料，初步分析了地应力对巷道稳定性的影响，为巷道的合理支护结构设计提供了可靠依据。

Abstract

The original in-situ stress is a basic parameter for the stability of surrounding rock support in underground engineering. The measurement and calculation are presented to determine the 3D in-situ stresses for Tangkou Mine. The surveys were carried out at different structural positions and depths and in different rocks using hollow inclusion measuring method in the ventilated and the west assistance conveyance stone door. The measuring depth reaches 1024—1030 m scope. Based on the determined in-situ stresses，their distribution characteristics are obtained by using theoretical analysis. The relationship between in-situ stress and geological tectonics is also studied; and some manful conclusions are obtained. The influence of in-situ stress on the roadways stability is analyzed elementarily so as to provide foundation parameters for supporting structure design.
