Study on Mountainous Shallow-Buried Coal Seam Mining Working Face Strata Behaviors and Overlying Strata Movement Features

摘要：

　　Through testing the mountainous shallow-buffed coal seam mining working face strata behaviors in Faer mine field,it got the strata behaviors:it was of large roof pressure,high rate of safety valve opening in hydraulic support,and even some supports crushed or took separation between top beams and tail beams.Traditional method of calculating supports resistance can not be applied to mountainous shallow-buried coal seam mining working face.With the discrete element simulation software UDEC it analyzed the strata movement feature,and got that the overlying strata took collapse and horizontal displacement after mountainous shallow-buried coal seam mined,and the strata movement feature was different between reverse slope mining and positive slope mining.
