| Abstract: | Based on the field observation,the paper summs up the deformating rule of gateway surrounding rock in lower seam of fully mechanized coal face with top coal caving in contiguous seams,while its upper seam had been mined.The reason of dead olad load acting on framed?teimber in gateway corner is discussed.Because of timber canopy strength lower,its being cracked phenomanon occurs,then solving this promblem method is putted forward. |
