摘要
从带压开采的角度建立了带压开采的三维固流耦合数学模型及其数值解法,并针对太原市东山煤矿带压开采,进行了三维固流耦合数值模拟,对带压开采底板的应力分布规律进行了详细的探讨,为进一步防治矿井突水提供理论依据。
In this paper,3-D solid-fluid coupling mathematical model and numerical solution is built from the point of view of mining with water pressure, and numerical simulations on 3D solid-fluid coupling for mining with water pressure in Dongshan coal mine of Taiyuan is carried out .The paper also discussed stress distributing laws of floor in the process of mining with water pressure,and provided a theoritical base for the prevention of water outburst from coal mine.
