%X By using in-situ measured data and the physical simulation technique,the structural characteristics of roof control with large mining height are studied.The mechanical model of roof control for the coal face with large mining height was put forward.According to different strata structures of the immediate roof,the immediate roof of the large mining height is divided into three types:type I,type II,and type III.Immediate roof type I will be calculated according to the given loading method and multiplying mining height method.Immediate roof type II is not suitable for large mining-height technique.The roof control of immediate roof type III should consider the thickness,location and engineering mechanical characteristics of the key layer of immediate roof.When the key layer of the immediate roof is closer to support load,the influence of shock loading should be considered.
