| 摘 要： | 运用Rosin-Rammler分布函数对伯方煤矿3#煤层煤样进行粒径分布情况的分析,得出结论:在双对数lnd-ln{-ln[1-F(d)]}坐标系下,所研究的材料颗粒分布的回归曲线为一条直线,R2=0.9672,线性回归良好。并得到了所研究粒径分布的具体函数表达式。由此可以对该煤层的冲击产尘的粒径分布有一个总体上的量化认识,为指导实际生产降尘、除尘提供了理论上的依据。

| Abstract: | Rosin-Rammler distribution function was applied to analyse the particle-size distribution(PSD) of Bofang mine 3# coal seam's coal sample.It comes to the conclusion: in the double-logarithmic coordinate system,the regression curve of the particle size distribution is a line,and R~2=0.9672,it proved the linear regression is perfect.Finally get the function expression of the PSD.It made us get the quantificational recognizability on the law of coal dust's particle size distribution,and provided theoretic evidence to direct the work and get rid of the coal-dust. |
