【摘要】 通过对盘江精煤金佳矿111811工作面风速场的数值模拟分析,得出巷道断面某点的风速与该点所在断面平均风速存在线性关系。利用数学软件Matlab对模拟数据进行曲线拟合,得出具体断面的线性函数,根据拟合函数可通过测量断面某点的风速求得该断面的平均风速。更多还原

【Abstract】 Making use of numerical simulation analysis about wind velocity field on 111811 working face in Panjiang Jinjia Coal Mine,this paper draws a conclusion that the wind velocity of a spot in section has a linear relation with average wind speed of this section.Dealing with the data from numerical simulation with mathematical software Matlab,linear function is simulated.According to the function fitting,average wind speed of section could be simulated by measuring wind velocity of a spot.更多还原
