Zusammenfassung: | The invention relates a construction method for underground rock drivage, in particular to a mechanized rapid construction method for traditional rock drivage. The method comprises the following steps: punching all blast-holes of a roadway head, carrying out guniting, charging and blasting in the lower blast-holes, carrying out ventilation safety inspection, charging and blasting in the upper blast-holes, carrying out ventilation safety inspection, temporary support and arch part support, at the same time, excavating waste rock 5 meters behind the roadway head, excavating waste rock within 5 meters of the roadway head, carrying out side part support, and then carrying out next circulation. According to the mechanized rapid construction method, a hydraulic drill carriage is adopted to punch holes, a side dump mucking machine is matched with a bucket loader to load muck, a belt conveyor is used to excavate waste rock, and therefore the method has the advantages of high blast-hole chiseling speed, high pore-form |
