摘　　要：采矿型液压凿岩机装卸钎杆的辅助作业时要求空打，否则时间过长，影响生产效率，而空打又容易造成活塞卡紧，现介绍一种即可空打便于卸钎而又消除活塞卡紧的具体措施的理论研究及实际效果。Hydraulic rock drill machine requires idle impulse when it load and unload drill steel, otherwise autiliary operating time is so long that its production is affected. Idle impulse easily causes piston jamming. A way in Which idle impulse makes unloading drill steel easy and piston does not get stuck is introduced.

关 键 词：液压凿岩机 卸钎 活塞卡紧 采矿
