多年来,各矿山单位一直都在计算三级矿量,都在强调保有足够的三级矿量。但是,标准究竟应该多少?如何正确地制定这一标准?人们常说的“三、一、六”标准(即开拓矿量可采期3年,采准矿量可采期1年,备采矿量6个月,以下简称“三、一、六”)对金属矿山中各类型矿井今天是否还都适合?是值得认真对待和研究的问
Over the years, all mining units have been calculating the amount of three ore, are stressed that there are enough three ore reserves. However, the standard should be how much? How to correctly develop this standard? People often say “three, one, six ” standard (that is open up the mining quantity can be reclaimed for three years, mining mining volume recoverable period of 1 year, Prepared for 6 months, hereinafter referred to as “three, one, six ”) for all types of metal mines in the mine today are still suitable?
