摘要
根据河南栾川钼矿马圈矿区民采空区处理方案,对其民采空区地压进行了数值模拟稳定性分析.采用RFPA’98软件分3种情况对民采空区顶板、矿柱进行了位移加载破坏过程的模拟,确定民采空区的危险区域,为预防预报民采空区的垮塌提供了安全技术依据.
According to the way of dealing with the mined-out area in Majuan mine area of Luanchuan of Henan province,we carry out a series of numerical simulation and stability analysis by the software RFPA'98. We do the simulation in three different conditions. After calculation,we draw the brocken process of roof baseplate,and ore pillar. Then we can know the dangerous point and it can give us the standard to forecast the dangers.
