地应力是影响地下工程稳定性的重要因素,要获取某一区域精确的地应力资料,必须进行地应力测量。与浅部相比,深部岩体具有“三高一扰动”的特性,其地质条件更为复杂,一些传统的测量技术已不能适应这种复杂环境。通过分析3种常用地应力测量方法在深部测量中面临的问题,结合收集的大量地应力研究资料,对深部地应力测量方法提出了改进技术与措施,以万福煤矿深部地应力测量为例,详细介绍了改进后的水压致裂法测量技术的实际应用情况,并针对今后地下工程呈现的新特点和新问题,分析了地应力测量的发展趋势,提出了个人的看法和意见。
Geostress is an important factor affecting the stability of underground engineering. To obtain accurate geostress data in a certain area, geostress measurement must be carried out. Compared with the shallow part, the deep rock mass has the characteristics of “three highs and one disturbance” and its geological conditions are more complicated. Some traditional measuring techniques can not adapt to this complex environment. By analyzing the problems in depth measurement of three commonly used methods of geostress measurement and combining with a large amount of research data of geostress collected, improved techniques and measures for deep geostress measurement are put forward. Taking the deep geostress measurement in Wanfu Coal Mine as an example, the detailed The actual application of the improved water pressure fracturing method is introduced. According to the new features and new problems of the underground engineering in the future, the development trend of the geostress measurement is analyzed and the personal opinions and opinions are put forward.
