摘要
采用有限元数值模拟计算方法 ,对新城金矿深部采场的 4种结构参数和 2种开采顺序等 6个方案进行了不同开采时期的优化分析和比较 ,获得了深部采场的最佳结构参数。研究中采用“品”字形连续开采的工作面布置方式可形成免压拱效应 。
Optimization analysis and comparision were made on the six schemes including four kinds of structure parameters and two kinds of mining sequence for the deep stope of Xincheng Gold Mine in different mining periods and the optimized structure parameters for deep stope were obtained.The working face configuration type of continuous mining applied in this study can form a free-of-pressure arch effect which is beneficial to the stope stability.
