摘　　要：随着龙首矿对深部开拓工程建设,为满足龙首矿深部采矿作业现场的通风和开发利用需要,金川镍钻研究设计院通过专家组论证并研究设计了中采区1340~1280中段27^(+24)通风竖井工程,井口、井脚标高分别为1340m、1280m,井筒高度60m,且该通风竖井与1340中段、1280中段进行贯通。通过制定通风竖井贯通测量方案,且实施贯通测量误差预计,保证龙首矿27^(+24)通风竖井工程能够安全顺利、准确贯通。结果表明:根据通风竖井贯通测量方案进行合理布设等级控制导线,确保了中采区1340~1280中段27^(+24)通风竖井按设计要求准确贯通。With the construction of the deep development project of Longshou Mine,Jinchuan Nickel&Cobalt Research and Engineering Institute has demonstrated and designed the 27^(+24) ventilating shaft project at level 1340 to level 1280 in mid mining area,aiming to meet the needs of ventilation within operating site and development.The elevation of shaft collar and shaft bottom is respectively 1340m and 1280m,and the shaft height is 60m.The ventilating shaft is connected with level 1340 and level 1280.Through making the measuring scheme of ventilating and conducting the estimation of measuring errors,the 2724 ventilating shaft project of Longshou Mine can be safely and smoothly and accurately connected.The results show that:reasonably arrange the distribution of grade control wire according to the measuring scheme of ventilating shaft connection,the accurate connection of the 27^(+24) ventilating shaft project at level 1340 to level 1280 in mid mining area can be ensured on the basis of design requirements.
