采金业必须倍加努力提高单位投资的生产率,进一步改善矿山环境和安全条件,创造高的就业机会,以保证本行业长盛不衰。在较长的时期内,只有采用先进的采矿方法和新工艺,才能使采金业得到真正的发展。坚硬、磨蚀性含金矿脉很薄,脉内金的分布不均以及大多数矿脉埋藏很深,这些特性影响着采矿的许多方面。 The gold mining industry must make double efforts to increase the productivity of its investment in units, further improve its environmental and safety conditions in mines and create high employment opportunities so as to ensure its long-term prosperity. For a long period of time, real mining industry will be able to develop only if advanced mining methods and techniques are adopted. Hard, abrasive gold-bearing veins are thin, unevenly distributed within the vein and most of the veins are buried deep, and many of these properties influence mining.
