摘　　要：根据采动岩体破坏下非线性渗流的特点,可知在破碎岩体中流体的流动状态既不是自由管流,也不是线性达西层流,所以不能用达西方程和Navier-Stokes方程来描述。提出采用Brinkman方程,研究在破碎岩体中水的流动规律,探究含水层在不同条件下对破碎岩体中的水渗流的作用机理,为正确预测水量和给定降水井数量提供参考依据。According to the characteristics of nonlinear seepage in mining rock mass damage. The fluid flow state is neither free flow in fractured rock mass, or is not linear Darcy laminar flow, so you cant use Navier - Stokes equation and Darcy equation. In this paper, using Brinkman equation, the research on the rules of water flow in the broken rock mass. Explore the mechanism of water seepage in broken rock mass in different water conditions. To predict water and dewatering well quantity provided the reference basis.
