In order to study the reasonable coordinated mining and the support technology, improve the mining recovery rate, 4224 mining area of Zhangcun Mine was taken as example, single roadway gob-side mining was considered the best continuous mining by AHP, based on the geological analysis of gob-side mining without filling, the support of single support combining with hinge joint to improve side goaf roof support was adopted, waste rock in goaf supporting gob-side roof, the maximum convergence of two sides of gob-side and roof and floor is 600 mm and 800 mm, the technology controlled the deformation of roadway and met the needs of roadway retaining.
