托库孜巴依金矿分段空场嗣后充填采矿法优化及数值模拟

Optimizing and Numerical Simulation about Sublevel Mining Method with Subsequent Filling in Tukuzbuy Gold Deposit

随着托库孜巴依金矿深部探矿工作的推进,须对井下采矿方法进行适应性调整,优化实施有底部结构的分段空场嗣后充填采矿法方案。采用Flac^(3D)软件对采准矿块结构、中段内回采及充填工艺匹配顺序进行三维数值模拟,对模拟结果数据的分析及采场稳定性计算结果表明,优化的采矿方案利于矿山整体稳定性及安全目标的实现;同时方案的实施改善矿山的地表作业环境和矿区的生态环境,提升矿山安全状态及企业品质,实现绿色开采。

As the advance of prospecting work in the deep of Tukuzbuy gold deposit, mine is need to adjust the plan of mining method. Optimization scheme is sublevel mining method with subsequent filling. The Flac3D is adapted to simulate and analysis the mining ore block structure and middle stopping and filling technology matching order. Through the analysis of simulation data and the stop stability calculation, the following conclusions were got： the optimization scheme of mining method help to achieve the goal of overall stability and security; the implementation of the plan at the same time is used to improve the surface of mine working environment and the ecological environment of mining area, the quality of mine safety status and enterprise are effectively improved, and green mining is realized.
