我国某些非金属矿的矿石工业指标,过去主要是参照国外经验和标准制定的。经过多年的生产实践证明,有的矿种的矿石工业指标、特别是质量指标不太符合我国目前矿山技术经济发展的现况,急待修订。另外,矿床的工业指标本来就不是一成不变的,随着采选技术的不断发展和改进、管理水平的不断提高,以及矿山资源的变化,应该有计划地对工业指标进行合理的调整,以适应当前的技术经济水平。国内不少同志对此作了许多有益的探讨。本文拟结合晶质石墨矿石质量指标的确定,寻求较为合理的制订工业指标的方法。
Some of China’s non-metallic mineral ore industry indicators, mainly in the past with reference to foreign experience and standards formulated. After years of production practice has proved that some mineral ore industry indicators, especially the quality indicators are not in line with China’s current technological and economic development of the mine status quo an urgent need to amend. In addition, the industrial indicators of the deposit have never been static, with the continuous development and improvement of the mining and dressing techniques, the continuous improvement of management level and changes in the resources of the mines, a reasonable adjustment of the industrial indicators should be made in a planned manner to adapt to the current The technical and economic level. Many domestic comrades made a lot of useful discussions. This paper intends to determine the quality indicators of crystalline graphite ore, to seek a more reasonable method of formulating industrial indicators.
