摘要
马钢罗河铁矿一期井巷开拓工程中,连接井下-455m采区水平和-560m水平主运输巷道之间的阶段竖井采用反井钻机进行施工,获得了成功的技术经验,并成功贯通成井三条,与传统的凿井方法相比具有相当大的优势。
In the first phase of mine development project of Masteel Luohe Mining Company,the raise boring method was used to construct the shaft from -455m working area to -560m level main haulway.This method has obtained successful experience,and cut through three pairs of shaft.Comparing with traditional shaft drilling method,raise boring mothed has obvious advantages.
