采煤机块煤产量确定方法的比较分析

Comparision and analysis of determining lump coal output methods for shearer

在假设采煤机的块煤产量服从指数分布、威布尔分布和均匀分布的条件下,分别建立了采煤机块煤产量的数学模型。利用计算机模拟的方法,对采煤机工作过程5~15、15~25与25~50mm三种粒度的块煤产量进行了数值模拟,并将结果与其实验值进行比较,确定了最优的分布形式。从而,为合理确定块煤产量提供了理论依据。

By supposing lump coal output obeying exponential distribution, Weibull distribution and u- niform distribution, The mathematical model of it is set up. The granularity of 5～15, 15～25 and 25～50mm while the shear is working is simulated by simulating software. The simulation result is compared with its experimental value and the optimal distribution is found out which provide a theoretical basis for determining resonablly lump coal output.
