白象山铁矿开拓运输方案优化选择研究

Optimization of the mining and transportation scheme of Baixiangshan iron mine

在矿山设计中,最为关键的是矿床生产规模论证以及采矿设计方案的确定.一旦采矿方法得以确定,优选确定相应的矿山开拓运输方案便十分重要.根据白象山铁矿的地质资源条件以及开采技术条件,指出适合白象山铁矿的采矿方法为连续倾斜进路尾砂充填采矿法和点柱充填采矿法.基于影响开拓运输方案的关键因素,定义了开拓运输设计方案评判指标体系,并建立了利用理想点法进行方案比较优选的方法.该方法在白象山铁矿开拓运输方案优化选择上为矿山决策人员提供了重要理论依据.

The most critical elements in mine designing process are the determinations of production scale and mining design schemes.The optimization of corresponding development and transportation schemes become very important upon determination of mining method.The most suitable mining methods for Baixiangshan Iron Mine are the continuous inclination drift with tailings fill stoping method and the pillar filling mining method according to its geological resources and mining conditions.An evaluation index system was constructed,and better schemes were selected out by ideal-point method based on the analysis of the key elements influencing the development and transportation schemes.It can provide valuable references for the mining management.
