矿岩综合分级定额标准初探

Discussion on Comprehensive Classification Norm of Ore—Rock

本文在岩石三性综合分级的基础上,结合我国新的岩石分级标准,通过大量的矿山生产测试和标定,研究制定了矿岩可钻性、爆破性及围岩稳定性分级的生产定额和材料消耗标准与其分级指数的量化关系,为加强矿山科学管理乃至国家投资概算提供了依据.

On the basis of the comprehensive classification of three properties for rock, combining the new rock classification standards in our country, and through considerable testing and demarcating of mine prodards of drillability and blastability of ore—rock, and stability classification of surrounding rock and the quantizied relation with their classification indexes. Thus, it provides the basis for the enhancement of mine scientific management and even national investment estimation.
