摘要
本文通过对十一个矿不同变质程度的主采煤层样品的宏观裂隙、微观裂隙的观测统计分析，得出了煤体中普遍存在的８种裂隙基本形式及其不同组合而形成的裂隙渗流网络，以及这些网络形式在不同变质程度煤体中的分布规律，并据此建立煤体裂隙渗流模型。
Based on the statistical analysis to the macro and micro cracks in the samples of the different metamorphosed coal seams from eleven mines,this paper comes to the conclusion that there are generally eight kinds of the basic crack network patterns in coal mass and that the others are their mutual combination. The distribution rules of the network patterns in the different metamorphosed coal are obtained in order to establish the crack water permeation patterns.
