煤(岩)的坚固性系数(f值)是煤(岩)与瓦斯突出防治过程中的重要参数之一。在理论分析的基础上,首先建立了评价采用捣碎法测定f值测定效果的数学模型,并提出了相应的评价指标,而后通过实验验证了该模型的实用性和准确性。
The solidity factor (f value) of coal (rock) is one of the important parameters in the prevention and control of coal (rock) and gas outburst. On the basis of theoretical analysis, the mathematical model for evaluating the effect of f-value determination by using the mashed-in method is set up first, and the corresponding evaluation index is proposed. The practicability and accuracy of the model are verified through experiments.
