机械部重型矿山机械总局和煤炭部基建司于今年3月底在洛阳召开了竖井钻机技术发展座谈会。会上,代表们回顾和总结了我国竖井钻机的发展概况、对西德L-40钻机进行了评议。认为国产竖井钻机在煤矿建井中立了大功,使钻井法得以生存和发展.随着钻机的不断完善和更新,其优越性越来越明显,用钻进法建井已势在必然了。会议还决定在L-40机型基础上,发展一种轻便高效的竖井钻机,并建议由洛矿所派员任总
Machinery Department Heavy Mining Machinery Administration and the Ministry of Infrastructure Construction Division at the end of March this year held a shaft drilling technology development forum in Luoyang. At the meeting, delegates reviewed and summarized the development of shaft drilling rigs in our country and commented on the L-40 rig in West Germany. It is considered that the domestic shaft drilling rig has made a great contribution to mine well construction and has enabled the drilling method to survive and develop.With the continuous improvement and renewal of the drilling rig, its superiority becomes more and more obvious. It is inevitable to build a well by the drilling method. The meeting also decided on the basis of the L-40 model, the development of a light and efficient shaft drilling rig,
