Roadway Hard Rock Loose Blasting by Digging Machine Technique
Rock roadway digging machine is generally applicable to soft mudstone, sandy mudstone roadway. When it comes to the harder rock,, the speed of digging machine construction is greatly reduced, the tool were wear seriously, the service life is substantially reduced, the tunneling cost is dramatic increased. So we must use the loose secondary blasting, to soften rocks. According to the specific circumstances of the west lane in Liuzhuang Coalmine, and proposed coal mine loose blasting technique program in keeping with construction requirements after the study, that is reasonable blast-hole depth, hole parameters, charge amount, charge structure, stemming length. Research results have a good loose blasting effect in engineering practice.
