【摘要】 近年来，灰色理论在控制和预测方面取得了很大的发展，但在采矿行业中应用不多，在岩石力学领域的研究更少。本文利用灰色关联度对岩石进行分类，并结合实例进行分析，试图为灰色理论在岩石力学领域的研究中起一点倡导作用。更多还原

【Abstract】 Over recent years the gray theory attains a great development in terms of con-trol and prediction technique,but in the mining industry it finds few applications,even fewer in the rock mechanics area. The rock classification is described by means of gray interralation level in this paper and is supported by case study aiming at playing a promotive roly in appli-cation of the gray theory to rock mechanics research.更多还原
