摘要
地压灾害在矿山伤亡事故中占绝对比重。通过对地压活动规律及其灾害表现形式的分析,采用三维有限元法对某铁矿岩体稳定性进行数值模拟计算,得出地压灾害活动规律并进行了安全分析,进一步提出了预防地压灾害的技术措施。
Ground pressure disaster occupies a predominent proportion in mine casualty accidents. Based on the analysis of ground activity law and its disaster presentation form, numerical calculation was made on the rockmass stability of an iron mine by three-dimension finite element method. The law of ground pressure disaster activity was deduced and safety analysis made. Technical measures for preventing ground pressure disaster were futher suggested.
