露天采场岩石二次爆破钻孔系统改造刘来庆（新岭煤矿黑龙江鹤岗 154106）摘要露天穿孔作业爆破后的岩石，产生部分体积较大的岩石0.5m3—1.5m3，无法正常装车，需要对岩石进行二次钻孔、装药、爆破，系统原有的压风机，动力源为汽车发动机，启动时靠司机脚踏油门，气压不稳定，常发生夹钻杆现象，且设备老化，工作效率低，故障高，无法满足生产需要。系统改造后，一键启动压风机，操作方便，减少职工劳动强度，耗能低，提高效率，安全性高。关键词岩石二次爆破康普斯压风机玉柴发动机一键启动

Renovation of secondary rock blasting drilling system in open pit Liu Laiqing (Xinling Coal Mine, Hegang 154106, Heilongjiang) Abstract The rock after open pit piercing operation produces some large rocks of 0.5m3—1.5m3, which cannot be loaded normally. The rock is drilled, charged, and blasted twice. The original compressor of the system is powered by the car engine. When starting, the driver's foot pedal is used. The air pressure is unstable, and the phenomenon of drill pipe clamping often occurs, and the equipment is aging and working efficiency. Low, high failure, unable to meet production needs. After the system is reformed, the compressor can be started by one button, which is easy to operate, reduces labor intensity of employees, consumes low energy, improves efficiency, and has high safety. Key words: secondary rock blasting, Compus compressor, Yuchai engine, one-key start

Renovation of the secondary blast drilling system of rock in open-air quarrying Liu Liqing (Xinling Coal Mine Heilongjiang Hegang 154106) Abstract After the blasting of open-air perforation operation, some of the larger rocks produced 0.5m3-1.5m3, which could not be Normal loading, the rock needs to be secondary drilling, loading, blasting, the system's original press, power source for the car engine, start-up by the driver's foot throttle, air pressure instability, often occur the phenomenon of drill pipe, and equipment aging, low efficiency, high failure, can not meet production needs. After the system transformation, one-click start blower, easy to operate, reduce the labor intensity of workers, low energy consumption, improve efficiency, high safety.
