摘要
以煤层具有的灰色性状为基点，运用灰色系统理论中灰色聚类的方法，结合宏观与微观两方面特征，选择煤层厚度的变异系数、煤分层数的变异系数、煤层灰分产率的变异系数和煤层厚度的不可采性指数作为聚类指标，对淮南煤田某井田煤层的稳定性进行定量评价，取得了比定性评价更接近客观实际的良好效果，并对我国现行煤层稳定性型别划分的不合理现象，提出了将煤层的稳定性细分为最稳定、极稳定、稳定、较稳定、中等稳定、较不稳定、不稳定、极不稳定和最不稳定计９个型别的新构思．
Based on gray form of coal seam, quantitative evaluation for coal seam stability is carried out in a mine of Huainan coal field by adopting gray clustering of gray system theory and combining with macro and micro characteristics, selecting coefficient of variation of coal seam thickness, number of coal slice and ash generation rate and nonminable index of seam thickness as cluster index, and good results which are more close to practice compared with qualitative are obtained. In view of existing irrational classification of coal seam regularity in China, a new concept of more detailed classification is put forward, they are: the most regular, extreme regular, regular, comparatively regular, moderate regular, comparatively irregular, irregular, extreme irregular and the most irregular.
