Abstract: Aiming at the roof control and removing passage stability and safety and other questions in the process of removing of large scale equipment in fully mechanized face, according to the geological and mining conditions in No.131108 fully mechanized face of No.2 Xinji Mine, three schemes are put forward, and after comprehensive economic and technological comparison, the best scheme we choose is as follows: brush expansion of cut-hole and auxiliary partial arrangement of safety chamber are used for the removing passage; other safe and effective measures are made to ensure the removing of conveyor and hydraulic support safety；after removing of the support，the wood crib and Point Pillar are used to support the roof on time，and protect the space for removing，prevent roof above the support caving. The industry research indicated that the implementation of scheme ensures removing of large scale equipment in No.131108 fully mechanized face safely，effectively and quickly，and has been achieved satisfactory technical and economical benefits.
