| 摘 要： | 在甲玛铜多金属矿地上地下并行大规模开采的复杂条件下,针对地下二期复杂厚大矿体的安全高效回采问题,综合分析矿山开采现状的基础上,提出2种盘区回采顺序方案,采用数值模拟方法对不同的盘区回采方案进行了分析优选,通过对比分析不同回采顺序条件下采场等关键部位的应力、位移的动态响应特性,确定盘区间隔回采方案最佳,该方案可为地下二期矿体安全高效开采提供技术支持。

| Abstract: | Under the complicated conditions of large-scale underground mining on the Jiama copper polymetallic ore site, based on the comprehensive and analytical mining status of the second-stage complex thick and large ore body, two types of panel mining sequence schemes are proposed. The numerical simulation method is used to analyze the optimization of different panel mining schemes. By comparing and analyzing the dynamic response characteristics of stress and displacement of key parts such as stope in different mining sequence conditions, it is determined that interval mining scheme is better. This program can provide technical support for the safe and efficient mining of the underground second stage ore body. |
