RESEARCH AND PRACTICE ON HIGH EFFICIENCY CONTINUOUS DRIVAGE FOR LARGE CROSS SECTION COAL ROADWAY

According to our country the machine excavation of coal roadway is widespread to exist a hard parallel performance of drilling and bolt supporting.The comparison of working faces and excavation exists the severity maladjustment in Shihe Coal Mine.New efficiently mobile roof bolter and bridge type conveyor are developped to succeed the wide adaptability.It is solved the equipments and key technology of drilling,supporting,conveyance,dust palliative.The new continuous tunneling drivage technology comes into being in large cross section coal roadway.It is achieved safe speedy drivage with many working procedures in coal roadway.
