By the full mine roadway pressure observation of Chensilou mine 21211 working face two roadway bolting support, the differences of roadway different sections at the seams and the surrounding rock deformation of different intensity of coal and roadway rock deformation under stress condition were illustrated, rock pressure data was regularly collected , with analysis and summary, on the one hand, abnormalities could be detected, with safety measures; on the other hand, through continuous monitoring of the mine pressure data analysis, which was able to objectively evaluate the scene reinforcement scheme and provided an important basis for the improvement and optimization of roadway design .
