| 摘 要： | 运用灰色预测理论结合VB编程,对煤炭回采成本中的各组成部分分别建立了预测模型,对平煤集团某煤矿的原煤回采成本进行了预测.经检验并与多项式回归方法及实际回采成本作对比,结果较为理想,使煤炭回采成本的预测更加符合实际,为煤炭回采成本的控制提供可靠的依据.

| Abstract: | Based on the grey theory and VB, a model is made for coal exploitation forecast, which is used to Pingmai company. By venifying and conitrasiting to multinomial model, it testifies that the grey theory model is very ideal in accordance with fact perfectly. The model offereds a gist for cost control.It also shows that the grey theory model could be used for coal exploitation forecast. |

| Keywords: | grey model multinomial regress cost forecast VB |
