Experimental study on surrounding rock deformation characteristics of gateway driving along next goaf with different thickness limestone roof

摘要：

　　The immediate roofs of gateways in Seams No.15U,16Uand 17 of Yanzhou Coal-field are generally limestone with different thickness.In order to maximize the self-bearing capacity of limestone,reduce the support costs of gateways and improve the production efficiency of the coal mine,research on the surrounding rock deformation of gateway 17304 under different limestone thickness driving along next goaf in Liyan Coal Mine was carried out.And then,it comes to the conclusion of the deformation laws and characteristics of surrounding rock which provide reliable basis for reasonable support designing of gateway driving along next goaf under different limestone.
