【摘要】：缓倾斜厚大矿体为采矿工程业界公认的难采矿体,随着采矿工程技术的发展进步,国内外矿山对这一难采矿体在采矿方法的选择和应用也发生一定的变化,充填类采矿方法在此类矿体开采方法所占的比重日益增加。与此同时计算机模拟软件在采矿工程中的运用也逐渐趋于普遍,因此有效合理的运用计算机模拟技术解决采矿工程工作中的各类问题必将成为业内未来的发展趋势。本文以云南省怒江州泸水县外岩房锡钨矿的生产问题为例,以采矿方法选择的安全性,经济性,合理性为原则,综合使用FLAC3D, MATLAB计算机模拟软件建立采矿方法初选模型,采场稳定性三维有限差分模型以及采矿方案优选模型。通过分析比对模拟结果最终确定了采矿方法以及其结构参数的选择,以下为主要研究内容：(1)收集整理云南省怒江州泸水县外岩房锡钨矿地质资料,结合国内外类似矿山生产实际建立适用于该矿山的采矿方法经济指标体系。(2)建立采矿方法初选模型,对可行的采矿方法进行初选,初步确定采矿方法。(3)以初步确定的采矿方法为基础,提出五个采矿方法结构参数方案,建立采场稳定性模型进行开采对比分析。(4)结合采场稳定性模拟结果以及各个方案的技术经济指标建立采矿方法综合评价体系,结合层次分析以及模糊数学理论对评级体系进行分析。(5)根据对采矿方法技术经济指标的分析结果提出最优方案,最终推荐矿山应用并指导生产。
[Abstract]:With the development of mining engineering technology, the choice and application of this difficult mining method in domestic and foreign mines have also changed, as the slow inclined thick large ore body is recognized as a difficult mining body in the mining engineering industry, and with the development and progress of mining engineering technology, the choice and application of this difficult mining body in domestic and foreign mines have also taken place. The proportion of backfill mining method in this kind of orebody mining method is increasing day by day. At the same time, the application of computer simulation software in mining engineering is becoming more and more common, so it will be the future development trend to use computer simulation technology effectively and reasonably to solve all kinds of problems in mining engineering. In this paper, taking the production of Wuyankang tin tungsten mine in Lushui County, Nujiang City, Yunnan Province as an example, taking the safety, economy and rationality of mining method selection as the principle, the primary model of mining method is established by using FLAC3D and MATLAB computer simulation software. The three dimensional finite difference model of stope stability and the optimal selection model of mining scheme are presented. Through the analysis and comparison of the simulation results, the mining method and the selection of its structural parameters are finally determined. The following is the main research content: 1) the geological data of the Wuyankang tin tungsten deposit in Lushui County, Nujiang Prefecture, Yunnan Province are collected and sorted out. Combined with the production practice of similar mines at home and abroad, the economic index system of mining method suitable for this mine is established. (2) the primary model of mining method is established, and the feasible mining method is selected. Based on the preliminary determination of mining methods, five schemes for structural parameters of mining methods are proposed, Establishing stope stability model for mining comparative analysis. 4) combining with stope stability simulation results and technical and economic indexes of each scheme, the comprehensive evaluation system of mining method is established. According to the analysis results of technical and economic indexes of mining methods, the optimal scheme is put forward, and finally the mine application is recommended and the production is guided by the analysis of the classification system based on the analytic hierarchy process and fuzzy mathematics theory.
