Abstract: With the successfully application and popularization of the fully mechanized coal mining technology,the mechanization level of coal mining is promoted constantly, a large number of large volume and heavy weight mechanized equipments are used widely in the fully mechanized working face, which can guarantee the safety production and also increase the difficulty of end-mining of the working face, so it is very important to complete the safety retracement of fully mechanized mining equipments when end-mining. Taking the end-mining of the 21002 fully mechanized working face as example, according to the specific geological production conditions of 21002 working face, the layout of remove gateway, the construction technology and the supporting pattern are studied, and the process of the technology, the technical requirements and the points for attention are also researched. The research results can ensure the safety retracement of fully mechanized mining equipments and accumulate valuable experience, and can be also references for other similar condition of end-mining.

Key words: end-mining of full-mechanized mining face, equipment removing, hydraulic support, preparation work, technological process
