Based on geological condition and disadvantages of 1003 working face in Qiyi Xinfa Mine, support and parameters were settled under the different condition, 2 observation station was set, the distance of the two 80 m, the observation once in two days, observation time 50 d. The deformation speed of roof and floor and two sides remained stable after 40 d. Displacement deformation of roof and floor 220 mm, two sides 180 mm, with good effect of avoiding surrounding rock deformation and technical and economical effect, providing reference for similar condition.
