摘　　要：文章结合工程实例,进行底板破坏深度回归预测,预计工作面底板的最大破坏深度可达16.11 m。分析了煤层开采扰动下的底板应力与变形,并提出了底板变形控制方法,包括充填开采、注浆加固和加快推进速度。经模拟分析,充填开采技术在控制底板变形方面效果最佳。This paper combines engineering examples to carry out the regression prediction of bottom plate failure depth,and predicts that the maximum failure depth of the bottom plate in the working face can reach 16.11 m.The stress and deformation of the bottom plate under the disturbance of coal seam mining are analyzed,and the control methods of the bottom plate deformation are put forward,including filling mining,grouting reinforcement and accelerating advancing speed.Through simulation analysis,fi lling mining technology has the best effect in controlling bottom plate deformation.
