hollow hole straight cut Application of Straight Cut Construction Technology in Large Section Tunnel With the continuous expansion of the construction market, the traditional manual drilling and blasting has gradually withdrawn from the application market, and the drilling jumbo has begun to show itself. Because the traditional inclined hole cutting drilling method has high requirements for the
dust removal system Study on dust removal system of DTH drilling machine In order to reduce the dust pollution produced by the down-hole drill in the working process, the dust removal system of the down -hole drill is designed. The working principle and composition of the dust removal system are introduced. The dust collection cover, cyclone dust collector, dust removal
rock drill COP1838 Rock Drill Working Principle and Common Fault Analysis The three-arm hydraulic rock drilling jumbo is equipped with a high-performance imported rock drill. If the rock drill breaks down frequently during tunnel excavation, it will seriously affect the construction progress and increase the construction cost. This paper analyzes the working principle
