摘要
从影响矿岩散体的非均匀度的三个要因素 (粒径离散系数、空间分布离散系数和孔隙分布离散系数 )出发 ,研究了崩落矿岩散体的非均匀度。给出了粒径离散系数Kf、空间分布离散系数Ks 以及孔隙分布离散系数Km 的定义和表达式。运用模糊综合评判决策得出Kf,Ks,Km 与散体非均匀度K有K =0 .5 85 5Kf+0 .112 5Ks+0 .30 2 0Km
In light of three factors affecting nonuniformity of loose body of ore rock, the nonuniformity of loose body of mullock is studied and the definition and expression describing the discrete coefficient, K f of grain-size, discrete coeffieient K s of space distribution and discrete coefficient, K m of operture distribution are given in this paper. Using comprehensive fuzzy assessment method, the authers have established the relationship of the nonuniformity, K of loose body with K f,K s and K m, namely, K=0.5855 K f+0.1125 K s+0.302?0 K m.
