沈阳风动工具厂于六四年試制成功了YT—25型气腿式凿岩机,并在煤炭部京西矿务局西山坑、冶金部寿王坟銅矿、紅透山銅矿和北京矿业学院等单位进行了长期工业試驗和生产使用后,六五年三月,經中央各有关部、科学研究单位、設計院、厂矿及高等院校等36个单位,进行了鉴定。現已基本定型,今年已投入小批生产。YT—25型气腿式凿岩机是供矿山鉆眼爆破、掘进巷道和采矿用的,同时又是鉄路、山地建設、水利、基建和国防工程中开采石方的主要机器,可在井下和露天鉆凿水平、向上和傾斜的炮孔,它适用于中等硬度
Shenyang Wind Tools Factory succeeded in trial production of YT-25 pneumatic leg rock drills in the 6th and 6th year, and was also in Xishankeng of Jingxi Mining Bureau of the Ministry of Coal, Shouwangfen Copper Mine of the Ministry of Metallurgy, Hongtongshan Copper Mine and Beijing Mining Institute. After conducting long-term industrial tests and production and use, and other units, in March and May of this year, 36 departments including the relevant departments of the Central Government, scientific research institutes, design institutes, factories, mines, and colleges and universities conducted assessments. It has been basically set. This year, it has been put into small batch production. YT-25 pneumatic leg rock driller is used for blasting in mines, excavation roadway and mining. It is also the main machine for mining stone in road construction, mountain construction, water conservancy, infrastructure construction and national defense engineering. It can drill downhole and open-pit Chisel horizontal, upward and inclined blast holes, it is suitable for medium hardness
