摘　　要：结合金川二矿区分段道的现场实际,采用数值模拟、相似材料模拟、技术经济比较和工程地质条件比较相结合的手段,对金川二矿区高应力条件下分段道的最优布置位置进行了研究。研究结果表明:分段道布置在溜井上盘,分段道围岩所处应力环境得到改善,围岩自身的稳定性提高,所受采动影响明显减小,有利于分段道的稳定;分段道布置在溜井上盘,虽然采准工程费用增加,但巷道返修费用减少,同时,分段道所处岩体的工程地质条件得到改善,也有助于分段道的稳定。According to the actual conditions of mining works in Jinchuan No. 2 mine area, numerical simulation, similar material simulation test, techno-economic analysis and in-situ geological engineering survey were combined to corporation research the optimal layout of sublevel drifts under deep high-stress conditions. The results show that the stress condition of surrounding rock of the sublevel drift is improved, the self-support ability of rock mass is enhanced, the sublevel drifts suffer less influence from mining work when the sublevel drifts are placed in the upper wall of the draw raises. The maintenance cost of sublevel drifts is greatly reduced though development engineering cost is increased. The geological engineering condition is improved when the sublevel drifts are placed in the upper wall of the draw raises, which is beneficial to the stability of sublevel drifts.
