基于灰关联分析的物元可拓模型在矿井底板突水等级判别中的应用

In this paper, a new approach to distinguish mine floor\'s water bursting, which makes use of grey relation analysis and matter-element extension model, is gived out. According to some mine\'s water bursting(including no water bursting) cases, calculating the weight of every water bursting factor in the way of grey relation analysis is first; distinguishing the level of every water bursting case to be assessed with the model of matter-element extension is second. Solution resulst are in line with facts, that the matter-element extension model based on grey relation analysis is appropriate and applicable.
