摘要
湘西金矿用传统的削壁充填法开采占生产矿量60％,但为了矿山的生存,仍有必要对该法在采场生产能力、作业劳动强度、生产安全等方面加以改善。工作的着眼点从提高机械化作业水平和采用抛掷爆破充填接顶技术入手。本文介绍所采用的新型削壁充填法的基本方案、现场试验结果及主要技术经济指标,并探讨了推广应用前景。
In Xiangxi Gold Mine, the traditional resuing-and- filling method accounts for 62% of the total ore production. For the survival of the mine, however, it is necessary to further enlarge the stope productivity, reduce labour intensity and improve working safety. Therefore, the original mining system has been modified, aiming at rising mechanization level and filling to the stope roof pin-point blasting. The basic scheme of the improved mining system is described along with its field test results and main techeconomic indices. Its application prospects are also discussed.
