摘要
以现场实测资料为基础,通过实验室相似模拟试验对云煤一矿两软一硬大厚差煤层上覆岩层垮落的特征及覆岩的移动规律、煤层工作面覆岩应力及超前支承压力的分布规律以及煤层工作面顶板的下沉规律进行了相关研究。研究的相关结论可指导生产实践,并为类似条件下煤层顶板控制提供理论参考依据。
On basis of the field measurements data, the overlaying strata＇s collapse characteristic and moving rule of two soft and one hard and largely inequality depth coal seam in Yunmei No. 1 Coal Mine, the distribution laws of working face＇ s overlying strain and its advance support pressure, and the subsidence law of working face＇s roof, were studied by analogue simulation. The studied results can be used to lead the practice, and it can also be used to as the theory base to working face＇s roof control in similar conditions.
