Abstract
Aiming at the problems of difficult support and low excavation efficiency in the rapid excavation of the 632 semi coal rock roadway in Huangling Coal Mine,the changes in excavation efficiency are analyzed through on-site actual measurement.The excavation efficiency is improved through the use of complete equipment and the improvement of support technology.Using theoretical analysis to analyze the stress distribution characteristics under rapid excavation,and analyzing the faulire situation of surrounding rock through roof borehole peeping.The results show that the roof adopts joint support,and the stress distribution under rapid excavation is mainly concentrated at the roadway;The analysis of the borehole peeping maps of the two sides and the roof shows that there are few fissures on the roof,mainly sporadic longitudinal fissures,indicating that the integrity of the roof is relatively good;The closure phenomenon of transverse and longitudinal fissures in the roof and the two sides is relatively obvious,and the joint support way is relatively suitable under rapid excavation disturbance,which can basically ensure the safety and stability of the roadway,and has certain guiding significance for the application of rapid excavation and support technology.关键词
