针对通常采用的(t)~(1/2)法、幂函数法、负指数法和对数法等4种瓦斯损失量推算方法,结合某矿的实测数据,分别从样本数据长度的影响、函数相关性、结果可靠性、实验室实测等方面,通过对比分析得出:对数法相对于其他方法,受样本数据长度影响较小,函数拟合相关度高,多组数据的差异性小,计算结果可靠性好,最接近于实测数据。
According to the calculation methods of four kinds of gas loss such as (t) ~ (1/2) method, power function method, negative exponential method and logarithm method, combined with the measured data of a mine, Function correlation, reliability of results and laboratory measurement. Through comparative analysis, logarithmic method is less affected by sample data length than other methods, the function fitting correlation is high, the difference of multiple data sets is small, The reliability of the calculation results, the closest to the measured data.
