摘　　要：根据我国地下矿山的情况，设计、研制的ＫＹ系列地下牙轮钻机具有分体结构。因而，机动灵活，操作方便。该系列牙轮钻机经在全国近十座矿山生产应用表明，它的结构合理、性能稳定、工作可靠、效率高。针对使用中暴露的问题，作者提出了两点改进意见。Series KY underground rotaty rig designed and developed according to the conditions of China's underground mines has the modular structure,thus it is mobie in maneuver and easy in operation. This series of rotary rigs were operated in about 10 China's mines ,and the results have shown that this rig is reasonable in structiure,stable in performance ,reliable in working and high in efficiency.Aiming at the problems exposed in operation ,the author puts forward two points of opinion on modification.
