一岩石硬度区分大家都知道,矿山岩石的硬软,对於探采工作有着极其重要的意义。当我们确定劳动生产率,制订经济技术定额以及决定选用某种采掘机械的时候,事前对于岩石硬度必须有正确的了解,否则便使工作难于获得预期的效果。打眼和爆破工作,是矿山生产过程中的两种基本作业;而岩石的硬度,正是影响这两种作业效率好坏的主要因素。因此,我们对于岩石的硬度应具有科学的,正确的分析知识。 A distinction between the hardness of rock We all know that hard and soft rock mining, exploration work has an extremely important significance. When we set the labor productivity, set the economic and technical quotas, and decide on the selection of a mining machine, we must have a correct understanding of the rock hardness beforehand, otherwise it will make it hard to get the desired results. Drilling and blasting are two basic operations in the mine production process. The hardness of rock is the main factor that affects the efficiency of both operations. Therefore, we should have a scientific and correct analysis of the hardness of the rock.
