多年以来,国内外矿山对于此类缓倾斜中厚矿体类型,一般都是广泛应用房柱法或底盘漏斗采矿法以及其它一些采矿方法。从某些矿山采用房柱法的生产实践经验来看,此法确实获得了较高的技术经济效果,并有利于实现回采作业机械化,是今后实现强化开采的重要条件。但是,此法的矿石损失率较大,甚至有的高达50%左右、造成地下有限资源的极大浪费,应该引起高度重视.再则,随着矿体厚度的增大,上盘围岩稳固性难于严密监测和处理,有时将危及回采作业的安全性,甚至影响此法的推广应用范围.再从某些矿山推广应用底盘漏斗采矿法的情况来看,此法确实是一种技术上易行.安
Over the years, domestic and foreign mines have generally adopted the method of house-pillar method or chassis funnel mining and other mining methods for such moderately inclined moderately thick ore body types. In some mines, the practical experience of adopting production method of column and column method shows that this method has indeed obtained high technical and economic effects and is conducive to the mechanization of mining operations, which is an important condition for enhanced mining in the future. However, this method of ore loss rate is large, and some as high as 50% or so, resulting in a great waste of limited resources underground, it should be attached great importance.And then, with the ore body thickness increases, the plate around the rock solid Difficult to closely monitor and handle, and sometimes will endanger the safety of mining operations, and even affect the promotion and application of this law.From some mining to promote the use of chassis funnel mining law situation, this method is indeed a technically easy OK
