摘　　要：夜长坪钼矿采用自然崩落采矿法,在生产中底部结构工程布置在极不稳定的氧化矿石中,巷道破坏严重,无法进行正常的放矿工作。通过采用FLAC软件进行数值模拟,对巷道支护形式及支护参数进行模拟计算,对不同的方案进行甄选,为现场支护方案和参数的确定提供重要依据。The natural caving mining method is adopted by Yechangping molybdenum mine, its bottom structure is layout in the extremely unstable oxidation ore in production process. Serious damage of the headings results that the ore drawing can not work normally. FLAC software is used to make numerical simulation to simulate the form of support and cal- culate the support parameters in order to contrast different schemes. This research provides an important basis for determi- ning the support scheme and parameter.
