The western coal bases will be0kNhe absolute subject of0kNhe future of China’scoal production growth.mining efficiency is greatly improved0kNhanks0kNolong-wallmining at present. Wellbore and0kNunneling is mostly used in drilling and blastingmethod for construction, which is slow, labor demand and0kNhere are some securityrisks.Boring has become an important factor0kNo limit coal production improvement.0kNherefore,0kNhe study of mechanized boring and0kNunneling meet0kNherequirements of national energy development strategy,which conducive0kNo speed upcoal mine construction.one of0kNhe limit for0kNhe popularization and application ofmechanized0kNunneling equipment is low efficiency for rock breaking and wear of0kNhe cutter.0kNhe rapid depletion of0kNhe cutter has greatly increased0kNhe cost ofmechanical0kNunneling, and reduces0kNhe efficiency of construction in0kNhe processof replacement of0kNhe cutter. A Reciprocating Liner Cutting0kNest platform isdeveloped according0kNo0kNhe development plan for0kNhe National EngineeringLaboratory for Deep Shaft Constration0kNechnology In Coal Mine, as a supplement0kNo0kNhe hob rock breaking0kNest methods, which used for rock breaking simulationwith full-size hob.principle of rock breaking as well as rock drill0kNest methods arepreliminary summary in0kNhe paper.
