牙轮钻机是露天矿山开采的主要设备之一,对采矿效率有着直接的影响。近几年来,我国分别研制了KY-250、KY-310型牙轮钻机,取得了一定成绩,但也存在着一些问题,在国民经济调整期间,为了进一步提高钻机性能,不断改进和提高主机与配套件的质量,一机部重型矿山总局不失时机地于80年4月15～16日在马鞍山召开了牙轮钻机技术座谈会。会上,洛阳矿山机械研究所介绍了牙轮钻机的使用情况、已暴露的问题及改进意见,有关配套单位主动表示愿意承担任务,最后,共同制定了攻关计划和实施办法。5月 Drill rigs are one of the major equipment for surface mining and have a direct impact on mining efficiency. In recent years, China has separately developed the KY-250 and KY-310 type cone drills and achieved some achievements. However, some problems still exist. During the adjustment of the national economy, in order to further improve the rig performance, Supporting the quality of parts, a machine Heavy Mine General seized the opportunity in April 80, April 15 to 16 held a roller-wheel drilling technology forum in Ma’anshan. At the meeting, Luoyang Mining Machinery Institute introduced the use of the cone rig, has been exposed problems and suggestions for improvement, the relevant units voluntarily expressed their willingness to undertake the task, and finally, jointly formulated the research plan and implementation measures.
