Abstract: Despite appropriate design of girder under bending and shear, the deflection of long steel girders usually exceeds the allowable range, and therefore the structural designers encounter......
美国马格玛铜矿的水砂充填系統Bruce Hull,燕洪波摘 要:在马格马铜矿,由于复杂的围岩条件,迫使它采用下向充填采矿方法,所用充填料是水泥和选矿厂的分级尾砂以及磨碎的炉渣的混合料.在22英尺垂直间隔的分段巷道上进行采矿.沿走向掘进10英尺宽的进路,並在完成几条进路之后就铺设包括纵向梁,横柱和金属网的垫层.在首先充填3英尺高的充填体中,尾砂和炉渣与水泥的比例是16:1,其余部分是28:1或35:1.在一个分段巷道上完成了采矿和充填作业时,采矿就转入下一个分段水平.梁和其它支护结构被包在充填体内,因此提供了比在原岩下作业更安全更快的采矿条件.这个方法可得到近乎100%的回采率和有限的貧化.到目前为止,对马格玛矿体是一个最成功的方法.关键词:......
