Abstract
In order to improve the tunneling speed and ensure the stability of the roadway,the research on the comprehensive mechanized tunneling technology of large section rock roadway was carried out in the centralized auxiliary transportation roadway of No.15 coal mining area in Xinjing Mine.Based on the analysis of the current construction technology and the problems existing in the support,the comprehensive mechanized rock roadway excavation operation line with EBZ320D roadheader and CMM2-25 bolt drilling machine as the main equipment was put forward.The strength strengthening theory of anchor cable surrounding rock was analyzed theoretically.Combined with the actual situation of the site,the support mode based on different length anchor cables was designed.The field application showed that after the application of the new comprehensive mechanized tunneling technology,the roadway deformation was small,the tunneling speed was fast,the construction cost was low,the economic and social benefits were remarkable,and the application effect was good.关键词
