摘　　要：通过模拟试验研究了煤岩散体落料冲击系数的影响因素,并探讨了各影响因素的影响规律。结果表明:散体落料高度以及缓冲层厚度对冲击系数均有较大影响。By means of simulating experiments, the affecting factors of the discrete material impact coefficient of coal have been studied, and the affecting rules of the various studied affecting factors have been also discussed. From the consequences, we find that the unloading height of the discrete material and the thickness of buffering layer have a larger effect on the impact coefficient.

关 键 词：落料冲击力 落料高度 缓冲层厚度 冲击系数
