Abstract
Based on conditions of Gengcuen coal mining (二 3)coal with sub-level caving mining.Applied method of similar materials simulation.Studied on process,varieties and characteristics of moving on roof strata are discussed.On the basis of model's results,effects in top-coal smash,and changes of peak value of abutment pressure within mining range are analyzed.
