Abstract
With the advancement of coal mining technology,the advancing speed and output of excavation work face are also increasing,and there are higher requirements for the excavation speed and efficiency of rock roadway.In order to solve the problem of non-parallel excavation and support,the 22306 floor rock roadway of Xiayukou Coal Mine is taken as the research object,and the mechanized equipment is introduced to improve the intelligent level and single-entry level of its excavation and support equipment.On the basis of ensuring the support strength,and in light of the"safe and reliable,and economical and reasonable"principle,the support parameters of the 22306 floor rock roadway is reasonably optimized,which realizes the step-by-step parallel operation of excavation and support,and greatly improves the efficiency of bolt and cable support.The monthly single-entering level of mine rock roadway is increased from 102 m to 241 m,which improves the overall exca-vation speed of rock roadway.The monthly advancing footage of rock roadway ranks advanced level in China,boosting the single-entering level of underground rock roadway excavation.关键词
