对回采巷道围岩稳定性分类进行了研究,建立了基于模糊等价关系的灰色Fuzzy聚类分析模型。利用该方法进行的回采巷道围岩稳定性分类,为确定合理的支护方式提供了依据,对提高煤矿的经济效益和社会效益有着重要意义。
The stability classification of surrounding rock in mining gateway has been studied, and a gray fuzzy clustering analysis model based on fuzzy equivalent relationship has been established. The classification of the surrounding rock stability of the mining gateway using this method provides the basis for determining the reasonable support mode and is of great significance to improving the economic and social benefits of the coal mine.
