摘　　要：根据岩层移动分层传递的观点,以综采面支承压力分布规律研究成果为基础,结合厚松散层下开采地表移动特征,建立了厚松散层下煤层开采沉陷预测模型。并利用该模型预测了谢桥矿8#煤层和6#煤层不同深度、不同工作面宽度的2个工作面开采沉陷值,得出相应的结论。According to the argument of stratum displacement due to stress delivered from separate stratum and also based on the research results from longwall face support pressure distribution regularity combined with the strata displacement characters when mining under loose and thick strata,the paper establishes a subsidence prediction model for coal mining under thick and loose strata.With the help of the said model,the paper predicts the subsidence values of the coal mining in 2 faces in the 8# and 6# coal seams in Xieqiao coal mine at different depth and different face width.The paper also presents the research conclusions.
