近几年来,我国金属矿山采用充填采矿法有了较大的发展,除现有十多个矿山采用推广外,尚有不少新建矿山正在试验研究和设计这种采矿方法。充填采矿法将具有较大的发展前途,因为,它可以及时处理采空区,维护岩层移动,防止地表陷落,保护地面的河流、良田和地面建筑物,特别对今后深部开采的地压控制,将具有较大的作用;同时,对富矿体的开采,可以提高矿石回收率,降低贫化率;对于夹层矿体,可以贫富兼采或分采,充分利用地下资源;尤其
In recent years, the use of metal mining in China has a larger development of mining methods, in addition to the existing more than a dozen mines to promote, there are still many new mines are experimental research and design of this mining method. Filling mining law will have a great development prospects, because it can promptly deal with goaf, to maintain the movement of rock, to prevent surface subsidence, to protect the ground of rivers, fertile fields and ground buildings, especially for the future of deep underground pressure control, Will have a greater role; the same time, mining of ore-rich ore, ore recovery rate can be increased to reduce the rate of depletion; for intercalated ore body can be rich and weak or both, and make full use of underground resources; especially
