摘要
以黄铁矿和方解石组成的岩石颗粒为研究对象,利用离散元方法建立简单二相矿物平面模型,为更好地表现微波照射下微裂纹的萌生和发展规律,模型采用平行黏结模型,考虑了影响微波照射效果的主要因素:功率密度、照射时长、矿物颗粒大小及形状,分析了在微波照射下吸波矿物晶体边界破坏过程及破坏规律。
The rock particles composed of pyrite are research objects, simple two-phase minerals plane model is established by using the UDEC （discrete element method）. In order to explain the appearance and development of micro-cracks under microwave irradiation, bonded type is set parallel-boned in the model. The influence effect of microwave power density, irradiation time, mineral particle size and shape etc. are considered.
