摘要
本文采用UDEC数值模拟对顶煤冒放性进行研究,离散元法是一种数值计算方法,特别适用于节理岩体的应力分析,在采矿工程方面有非常重要的应用。UDEC用于模拟非连续介质承受静载或动载作用下的响应。非连续介质是通过离散的块体集合体加以表示。通过数值模拟对顶煤的冒放性做了很好的分析,指导了实际工作中遇到的问题。
This paper uses UDEC numerical simulation to study top coal caving,Discrete element method is a numerical method,Particularly,It applys to stress analysis of jointed rock masses. In mining engineering,it is an very important application. UDEC used to simulate non-continuum response under of static or dynamic load.Non-continuum is through collection of discrete blocks to express.numerical simulation makes a good analysis to the top coal caving. It guides encountered problem,which appears in the practical work.
