寻找一个有效的和经济可行的方案来代替常规的大型板状矿床地下开采的木支护,其理由已经是众所周知,毋庸赘述.把胶结尾砂用泵送到回采工作面,可减少包括运搬支护材料在内的劳动力.由于这个方案对于南非金矿来说是新的,设计的指导者对此是小心谨慎的.现在,已经积累了泵送和堆积尾砂的比较成熟的经验.关于就地取材的材质方面的知识,仍须进一步探讨,这就是进一步研究的题目. The reason for finding an effective and economically viable alternative to the subsurface mining of timber support in conventional large plate-like deposits is well known and needless to say.When cementing the tailings is pumped to the mining face, Workforce, etc. As the program is new to the gold mine in South Africa, design mentors are cautious about it and now they have accumulated more proven experience in pumping and pooling tailings. The knowledge of the materials in place still needs to be further explored, which is the subject of further study.
