摘要
本文以某矿井巷内的重要贯通工程为研究背景,贯通导线全长约为13 000m。导线按7″基本控制导线的精度进行要求,井下7″控制导线网以总回大巷中的H25、H26两点为起始点,经45202运输巷道、开切眼到贯通点K形成闭合导线网。
In this paper, the important piercing project in a mine roadway is taken as the research background, the total length of penetrated wire is about 13 000m. Conductor according to 7″ basic control wire accuracy requirements, the starting point of underground 7″ control traverse network is H25 and H26 in the total return roadway, closed traverse network is formed through 45202 haulage roadway, open-off cut and through point K.
