摘要
在三轴应力状态下煤样渗透系数的实验研究基础上，分析了影响煤层渗透性的几个主要因素；探讨了煤体中裂隙分布的分形特征。根据模糊数学的基本理论，提出了煤层注水渗透性的分类方案；给出了对一些矿区主采煤层的分类结果。
On the basis of the experimental study of permeability coefficient for coal sample under triaxial stress state,this paper analyses the primary factors to affect coal seampermeability and approaches the fractal feature of the crack distribution in coal mass.Based on fuzzy mathematical theory,the permeability classification plan on infusion in coalseam is put forword and the classification results for the main seams in some mining areasare given.
