随着南非金矿开采深度不断增大,采用充填采空区来控制岩爆和过大的岩层压力而引起的采场闭合就显得十分必要。现就南非矿山深部开采中充填料输送系统的设计现状介绍于后,并着重介绍管道压力梯度和磨损及其充填料输送系统设计的发展前景。
As South Africa’s gold mining depth continues to increase, the use of goaf to control rockburst and overburden pressure caused by the closure of stopes is necessary. The current status of the design of the filling material delivery system in deep mining in South Africa is presented below and the development prospects of pipeline pressure gradient and wear and the design of the filling material delivery system are highlighted.
