摘要

为研究放顶煤液压支架的放煤过程和直接顶与基本顶之间的破断规律,以ZF15000/28/52型出口放顶煤液压支架为研究对象,采用EDEM离散元仿真软件建立三维仿真模型,综合考虑煤岩颗粒、成分对放煤规律的影响,得到液压支架放煤过程、煤岩颗粒运动趋势和速度及直接顶和基本顶的粘结力链,仿真结果与实际落煤情况基本一致,为研究液压支架放煤过程提供了一种新的思路。

Abstract

In order to study the caving process of caving coal hydraulic support and the breaking law between immediate roof and basic roof,Taking the ZF15000/28/52 export caving hydraulic support as the research object, establish a three-dimensional simulation model by EDEM（an discrete element simulation software）,Taking Comprehensive consideration the effects of coal and rock particles and composition on coal caving,finally obtained the coal caving process with hydraulic support, the movement trend and velocity of coal and rock particles and the bond force chain of immediate roof and the basic roof,The simulation results are basically consistent with the actual coal caving process, which provides a new way to study the caving process of hydraulic support.
