摘要
基于COMSOL Multiphysics软件进行本煤层开挖模拟研究,结合工作面围岩力学特征,将煤层开挖高度由原有的本煤层采高优化为采高和冒落带高度之和,并结合某矿工作面实际情况对其前方的"横三区"中的超前卸压区和应力集中区宽度进行了现场实测,验证了改进后模拟模型的可靠性,优化后模型对相关方向的模拟研究具有一定的借鉴意义。
Based on COMSOL Multiphysics software, simulates the excavation of the coal seam.Combined with mechanical characteristics of surrounding rock of working face, the excavation height of coal seam is optimized from the original mining height of coal seam to the sum of mining height and caving zone height.Combining with the actual situation of a mine working face, the width of the advanced pressure relief zone and stress concentration zone in the "horizontal three zones" in front of it is measured in situ.The reliability of the improved simulation model is verified.The optimized model can be used for reference in the simulation of related directions.
