摘要
通过对水银洞金矿1 240 m中段506采场矿压的现场监测,绘制了506采场压力随工作时间和工作面推进的曲线图,对压力曲线进行分析、对比和研究,揭示了506采场的矿压变化规律,确立了工作面最大推进长度为6 m。结合地质资料采用FLAC软件对506采场进行数值模拟和采场支护经济比较,充分验证了6 m是既能保证安全生产,又能大幅降低成本的间距。
Through the site monitoring of 506 stope mining pressure in 124 0 m middle - section of Shuiyindong Gold Mine, graph of 506 stope pressure with working time and working face advance was drawn and analyzed, compared and studied, mine pressure change law of 506 stope was revealed, 6 m was the most length of working face advance confirmed. Numerical simulation and stope support economic comparing were done on 506 stope combined with geological data using FLAC software, making sure that the 6m was the safe spacing in production as well as reducing cost greatly.
