摘要: 庞庞塔矿5107作为一个孤岛综放工作面,回采难度很大。如何既能安全回采又能最大的回收资源是需要解决的问题,庞庞塔矿进行了专项煤柱留设技术研究。通过对围岩强度测试,用理论分析和数值模拟的方式确定了煤柱尺寸,达到了回采要求,多回采煤炭资源22 万t。
关键词: 孤岛工作面, 深部倾斜煤层, 煤柱留设, 高应力, 数值模拟
Abstract: Pangpangta Mine 5107 as an island fully mechanized caving face,mining is very difficult.How to recover resources safely and maximally is a problem that needs to be solved.For this problem,Pangpangta Coal Mine has carried out special coal pillar setting technology research.Through the strength test of surrounding rock,the size of coal pillar is determined by theoretical analysis and numerical simulation,which meets the requirements of mining,and more than 220 000 t of coal resources are recovered.
Key words: Island coal face, Deep inclined coal seam, Pillar setting, High stress, Numerical simulation
