冲击地压研究现状与数值模拟分析
首发时间:2009-02-23
摘要:本文总结了近几十年来冲击地压理论研究进展,并对国内外现今所采用的预测和防治措施进行了分析,采用了损伤力学的理论对冲击地压进行研究。在数值模拟上主张采用有限元法取代有限差分,使适用范围更广泛。同时针对采空区移动特点,初涉了动态坐标的应力场数值模拟,对今后的预测预报工作给予指导。

Analysis on the Present Research Advance and Numerical Simulation of Rock Burst
Abstract:The paper summarizes the present research on the theory of rock burst in recent years, analyzes the method of prediction and forecast adopted both at home and abroad, research on the rock burst with the theoty of damage mechanics. Advocated the finite element method replace the finite-difference in the numerical simulation for the wider scope of application. At the same time, propose the coordinate system in dealing with numerical simulation in stress field for the moving work-out section. It will give the direction for the prediction and preventive measures in future.
Keywords: Rock burst Present situation Damage mechanics Numerical simulation
