由洛阳矿山机械研究所设计、江西采矿机械厂制造的我国第一台KY—310型牙轮钻机高钻架,于1984年9月1日在大冶铁矿投入生产。到1985年8月底七个月内,在f=14～16矿石上总进尺17476米,最高台月进尺4308米,创该矿台月穿孔的最高纪录。为总结经验和推广高钻架的应用,机械部重矿局于1985年4月27～29日在大冶铁矿主持召开了KY—310型牙轮钻机高钻架的总结评议会,有25个单位的54名代表参加了会议。
Designed by Luoyang Mining Machinery Research Institute, China’s first KY-310 high-powered cone drill rig manufactured by Jiangxi Mining Machinery Factory was put into production in Daye Iron Mine on September 1, 1984. By the end of August, 1985, the total footage of f = 14 ~ 16 was 17,476 meters and the maximum height of the month was 4,308 meters, the highest monthly record of perforation in this mine. In order to summarize the experience and promote the application of high-rig, Heavy Machinery Bureau Heavy Machinery Bureau convened a summary council of KY-310 type high-powered drill frame drill rig at Daye Iron Mine from April 27 to April 29, 1985, with 25 A total of 54 representatives attended the meeting.
