摘　　要：基于相似三定律,采用相似材料模拟的实验手段,侧重"三带"发育的动态过程,分析"三带"的分布情况,为矿井瓦斯的高效抽采提供依据。在数据处理方面,采用经验公式、实验手段相结合的方法,保证实验结论真实有效,对现场钻孔的设计具有指导意义。Based on similar three laws,the similar material simulation experiment is the method that the authors have taken. To provide efficient basis for gas extraction effectively, the authors have focused on the dynamic process of the development and the detailed distri- bution of ＂three zones＂. In data processing,they not only think about experience formula but also experimental means,to guarantee the conclusion which has guiding significance to the design of the drilling is real and effective.
