摘要
通过对钻孔瓦斯涌出初速度的影响因素的综合全面理论分析,运用量纲理论和方法分析其影响因素的量纲,建立起钻孔瓦斯涌出初速度的数学模型。根据所得的数学模型进行理论分析并和原来重庆研究院得出的数学模型进行比较分析研究后,初步得出此模型更有实际应用价值的结论。
Through the comprehensive theoretical analysis of drilling gas emission factors,using dimensional theory and its influencing factors in the party dimension,the paper established a mathematical model of drilling gas inrush initial rate.According to the mathematical model derived from theoretical analysis and the original model obtained from Chongqing Institute,the paper achieve more practical value of conclusions.
