根据灰色理论中的ＧＭ（１１）模型，建立起一个矿山矽肺病人数预测模型，并应用这个模型建立了某矿矽肺病人数预测模型。经验算，这个模型精度较高，为预防和减少矽肺病人数提供了理论依据，对矿山安全生产有一定指导意义。 According to the GM (11) model in gray theory, a prediction model of the number of mine silicosis patients was established. Based on this model, a prediction model of the number of silicosis in a mine was established. Experience shows that the higher accuracy of this model provides a theoretical basis for preventing and reducing the number of silicosis patients and has some guiding significance for mine safety in production.
