| Abstract: | In order to obtain the distribution of in-situ stress in deep rock mass,taking Dongrong No.2 Mine as the research background,this paper introduces the commonly used in-situ stress testing methods,and focuses on the principle and process of stress relief method.The results show that the stress field in Dongrong No.2 mine belongs to the medium and high ground stress field in terms of magnitude,the two sides of roadway are greatly affected by vertical stress,and the roof and floor are greatly affected by horizontal stress. |
