希腊中部的地下铝矾土矿采用房柱法开采。房柱法能充分机械化,获得较高的生产率。但是工作地点分散、设备移动频繁,且移动线路受到限制,给分析研究工作带来不便。这些问题可通过本文所介绍的NTUSIM新型程序解决。这种程序可以预测房柱法的生产能力,并可研究不同设备、不同设计方案及不同维修设施对生产系统的影响。本程序可以模拟工作面的凿岩、装药爆破、撬毛、装运矿石与顶板支护五个工艺,还可同时模拟几个采区的开采工艺。 为了对主要工序进行模拟,需要分析研究各工序所需时间、设备效率及其标准偏差、运输设备的运输路线、运行速度、故障时间
The underground bauxite mine in central Greece is mined by the column-and-pillar method. Housing method can be fully mechanized, access to higher productivity. However, decentralized workplaces, frequent equipment movement, and limited mobile lines have created inconvenience in analytical work. These problems can be solved by the new NTUSIM program described in this article. This program can predict the production capacity of the house-and-column method and can study the impact of different equipment, different design options and different maintenance facilities on the production system. This program can simulate the face of rock drilling, charge blasting, pry hair, ore loading and roof support five processes, but also simulate several mining area mining process. In order to simulate the main process, the need to analyze the process of the required time, equipment efficiency and standard deviation, transport equipment, transport routes, operating speed, downtime
