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。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 func- tion fitting, average wind speed of section could be simulated by measuring wind velocity of a spot.
