断层突水的力学机制浅析

Preliminary Analysis of Mechanical property of Water Inrush from Faulits

煤层底板突水事故频发，给煤炭工业造成了巨大的经济损失；据统计资料，大部分突水事故都是由于断层引起的。文章基于岩体极限平衡理论，分析了煤层底板突水和断层突水的力学机制，给出了底板及断层附近是否突水的判别公式，并由实例进行了验证。

Abstract Frequent occurrence of water inrush from seam floor has brought great economic loss for coal industry.It is indicated that water inrush accidents almost are induced by faults.The mechanism of water inrush from floor and fault are analyzed dynamically based on the limit balance theory of rock in this paper.A discriminant is proposed to judge if water inrush will occur near floor or fault,and demonstrated by practice,which provides a scientific basis for safe mining above water.\;
