峰峰矿区矿井突水分类及发生机理研究

STUDY ON THE WATER INVASION CLASSIFICATION AND MECHANISM IN FENGFENG MINE AREA

在对峰峰矿区大量突水实例深入分析的基础上，根据隔水岩体初始特性即有无断层构造及其规模大小，将矿井突水分为完整隔水岩体突水、小断层破碎带突水及大断层突水三种类型。应用岩体变形与破裂机制和岩体水力学原理，对上述三种类型突水的发生机理进行研究，并讨论预防方法。

Based on a large number of case histories of water invasion happened in Fengfeng mine area, the paper classifies water invasion into three kinds: water invasion from complete watertight rockmass,from small fault and from large fault according to the character of water rockmass. With the rock mechanics and groundwater permeation theory, the author study the mechanism of three kinds of water invasion,then put forward some methods to prevent water invasion.
