Abstract: Movement and failure of overlying rock caused by mining of deep coal seams.The weak intercalated layer is one of the key factors influencing the stability of the surrounding rock stability of the shaft,the chamber and the underground tunnel.In order to study the stability of surrounding rock of inclined shaft with weak intercalated layer in weak cementation sandstone,the model of statics account at weak intercalated layer based on stratified displacement field.It calculates the exact displacement of each point of the soft and hard rock layers.Theoretical analysis and numerical simulation method are used to analyses surrounding rock deformation law,which is affected by the soft and hard rock layers elastic modulus ratio,weak interlayer poison’s ratio and the thickness.The results showed that there are significant effects on surrounding rock stability of the Inclined Shaft with soft and hard rock layers elastic modulus ratio.When the k value is less than 0.1,that is,when the elastic modulus of the soft layer and the hard layer differs by one order of magnitude and above,the deformation of the surrounding rock increases significantly,and the two becomes a power function relationship.The stress gradient between the weak and the upper and lower hard layers increases with the decrease of k.The maximum deformation occurs in the inclined roof and floor at the junction of soft and hard layer.The deformation of surrounding rock slope decreases with the Poisson's ratio of weak intercalation layer is increased from 0.1 to 0.4,roof displacement decreases 0.42m.The greater the thickness ratio,the worse the stability of the surrounding rock.The roof to floor displacement is about 3 times of that of the two sides in inclined shaft.
