摘要
本文根据漳村煤矿3-#煤层回采工作面测量的瓦斯浓度值,使用最小二乘法,结合Matlab软件,运用线性、多项式、指数、对数函数的曲线拟合方法对回采工作面瓦斯浓度进行拟合,得到了瓦斯浓度与回采工作面距离之间的函数,从进风侧到回风侧瓦斯浓度呈递增状态,在两头瓦斯浓度趋于稳定,通过计算各拟合曲线的均方误差,找出最优的拟合方案,为防治瓦斯工作提供参考依据。
According to the gas concentration in Zhangcun Coal Mine 3# coal mining face value measurement and using the least square method of mathematics thought, and combined with the Matlab software, curve fitting method of linear, polynomial, exponential, logarithmic functions were used to fit the working face gas concentration, getting the function of the gas concentration and the distance of the working face, the gas concentration was increasing from the inlet side to the return air side, the gas concentration tended to be stable at both ends, by calculating the mean square error of fitting curve, the best scheme of fitting was found out, to provide reference for the prevention and control of gas.
