在合同条件下完成的实验室试验表明,高密度充填体可以在深部矿山开采中达到减少或控制危险的岩爆和恶劣的岩层条件。计算机模拟试验表明,由振实的尾矿、废石和水泥构成的高密度充填体,与一般充填体相比,能承受4倍以上垂直于采空场的作用力。在阿纳康达矿产公司卡尔福尔克(Carr Fork)矿完成了VCR采矿法试验采场的采矿及其采后废石充填。据有限元模型试验和
Laboratory tests performed under contract conditions have shown that high-density fillings can reduce or control dangerous rockburst and poor rock conditions in deep-mine mining. Computer simulation tests show that the high-density filling body composed of tapped tailings, waste rock and cement can withstand more than 4 times the force perpendicular to the mined-out field compared with the general filling body. The mining of the VCR mining test stope and its post-mining waste rock fill were completed at the Anaconda mining company, the Carr Fork mine. According to finite element model test and
