文摘Based on the analysis of regional geology,the analysis from the results of measurement of mine in situ stress show conclusions that the coal bed tunnel of Jincheng Coaling Group is related to the horizontal stress,and that does big horizontal tectonic stress.The measured results develop the basis for engineering design,the analysis of stability,proper tunnel layout,and supporting designing.Aiming at the characteristics of big horizontal stress,give some relevant technical measures,and have effectively controlled surrounding ground displacement and destruction.
