According to the practical situation on the spot of Fenghuangshan coal mine and the rock pressure in mine observation, the features of the deformation of wall rock and support load of bracket have been analysed. Combining the maintenance principle of pressure relief and timbering, it has stated the principle of the support pattern of wall rock creeping and pressure relief. The pressure relief in driving roadway along the goaf is successfully processed in the upper return airway of working face 2322 so as to realize non-engineering for repairing during its life. Thus, the maintenance expenses are saved, the loss of high quality coal resources are decreased, the advantage the recovery rate of coal resources and economical benefit of mine are increased. This support pattern has a simple production process, lower costs and easy spreading.
