一、目前的问题(一)片面认为石灰石资源到处可见,是“低价值”原料,不适当地强调低成本,搞无剥离或少剥离。开采中弃贫采富,只要近距离、高品位,要山头不搞凹陷,造成资源的浪费与积压,资源利用率仅达30～50%。(二)由于受种种条件的限制,使可采储量大为减少。据统计,1980年全国大小石灰石矿点共529个,工业储量(B+C)约99亿吨。但大于3000万吨的矿点仅150多个(储量约60亿吨),其中80多个尚未利用的矿点,能符合大中型水泥厂要求的还不到20%。 First, the current problems (A) one-sided view that limestone resources everywhere, is a “low value” raw materials, improper emphasis on low-cost, engage in no or less stripping stripping. Mining abandoned rich and poor, as long as the short distance, high grade, to sabotanks, resulting in the waste of resources and backlog, resource utilization rate of only 30 to 50%. (B) Due to the restrictions of various conditions, the recoverable reserves are greatly reduced. According to statistics, a total of 529 large and small limestone mines nationwide in 1980 with an estimated industrial reserves of 9.9 billion tons (B + C). However, there are more than 150 ore mines (about 6 billion tons of reserves) with more than 30 million tons. Among them, more than 80 unused mined spots meet the requirements of medium and large-sized cement plants less than 20%.
