摘　　要：为解决薄煤层开采条件下缓倾岩质的稳定性问题,建立岩层移动规律模型,并通过分析发现,冒落带上方岩层对山体变形有显著控制作用,可视为关键层。文章通过模拟山体失稳机制数值,对比分析不同开采方案下山体变形的规律及稳定性。结果表明,层间下行后退式开采对山体稳定性的影响显著,层间上行前进式开采会加速斜坡变形,而填充开采法则能有效减小山体变形,为煤层开采中的地质灾害防治提供了科学依据。In order to solve the stability problem of gently inclined rock mass under the condition of thin coal seam mining,a model of rock layer movement law is built.Through analysis,it is found that the rock layer above the caving zone has a significant control effect on the deformation of the mountain,which can be regarded as the key layer.By simulating the numerical value of mountain instability mechanism,this paper compares and analyzes the law and stability of mountain deformation under different mining schemes.The results show that the interlayer downward retreat mining has a significant influence on the stability of the mountain,the interlayer upward advance mining will accelerate the slope deformation,and the filling mining method can effectively reduce the deformation of the mountain,which provides a scientific basis for the prevention and control of geological disasters in coal seam mining.
