煤和岩石物理力学性质测定方法 第 12 部分: 煤的坚固性系数测定方法
Application Summary AI generated
This standard specifies the testing method for determining the hardiness coefficient of coal, which is a key parameter for evaluating coal's resistance to crushing and fragmentation. It is applied in the mining industry, particularly for coal mine design, rock burst risk assessment, and the selection of cutting or drilling equipment. The method is used in both laboratory and field testing contexts to ensure safe and efficient coal extraction operations.
