摘要
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 firmness coefficient of coal （rocks） is one of the most important parameters in the process of coal （rock） and gas out- burst prevention and control. On the basis of theoretical analysis, this paper firstly establishes the mathematical model which is used to evaluate the determination effect off value by pounding method, and puts forward the corresponding evaluation index. The practicality and accuracy of the model are verified by experimental results.
