摘要
针对现有煤层冲刷带的分类及其命名存在的问题,提出了新的分类方案,阐述了煤层冲刷带各类型的主要特征,并介绍了煤层顶（底）板砂体等厚图对煤层冲刷带的预测作用,预测方法步骤及预测实例。
To solve the problems of the classification of erosion zones and their types.existing in coal seams, a new classification is presented and the main characteristics of various erosion zones are described in this paper.Besides,the predicting roles played by the isopach map of sand bodies of the roof(footwall) in coal seam for erosion zones are introduced,and the predicting methods,steps and examples are also given.
