摘要
金川二矿区随着开采深度逐渐加深,地应力呈线性增大,面临着诸如巷道、采场稳定性及生产效率低、成本高等突出问题。作者提出,为安全、高效地开采金川二矿区深部矿段,应加大技术创新力度、统筹规划开拓工程和开采顺序,使各开采盘区均衡下降,改善围岩受力特性,提高锚杆支护系统的强度。
As mining goes deeper in Jingchuan's No.2 Mining District, ground stress grows linearly and problems arises such as unstability of workings and stopes, lower mining productivity and higher cost. It is pointed out in the paper that to guarantee safety and high mining productivity of the deep orebody in Jingchuan's No.2 Mining District, technical innovation should be intensified and development and mining sequence should be planned as a whole so as to lower the various mining panels evenly, modify the stress exertions of wall rocks and enhance the strength of the bolt supporting system.
