摘要
西石门铁矿回采巷道围岩变形破坏严重,破坏形式复杂。本文通过对西石门铁矿的现场调查,得出影响回采巷道围岩稳定性的主要因素,并以这些因素为分类指标,根据模糊聚类分析原理,采用VB6.0语言建立分类程序,对西石门铁矿回采巷道围岩进行分类。在回采巷道围岩分类的基础上,本文又进行了回采巷道支护方法研究,针对不同类别的巷道围岩分别提出相应的支护方案。
The surrounding rock of the gateway in Xishimen Iron Ore Mine has been broken very terri bly. The deformation of them was very complex, we analysed the stability influencing factors of the gateways＇ surrounding rock and chose the indexes of classification, we built a programme in VB6. 0 language to classify the surrounding rock of the gateways in Xishimen Iron Ore Mine based on the theory of fuzzy clustering. Considering the classification results, then researched how to support the surrounding rock. According to different classifications, we put forward the corresponding methods to support them.
