摘　　要：根据凤凰山煤矿现场实际情况 ,在矿压观测的基础上 ,分析了沿空巷围岩变形及支架载荷特征 ,结合卸压支护的维护原则 ,阐述了围岩蠕变卸压支护方式的原理 ,成功地在2 32 2工作面回风巷进行沿空掘巷卸压支护 ,实现了该巷道在服务期限内无维修 ,节约了维护费用 ,减少了优质煤炭资源的损失 ,提高了煤炭资源回采率和矿井的经济效益 .该种支护方式工艺简单、费用低、便于推广 .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.
