According to the practical case of Fenghuangshan Mine,the destruction reason of support for previous roadway is analyzed. Combining the maintenance principle of pressure relief and support,the principle of pressure–relief support is interpreted with the consideration of wall rock creeping and pressure relief. Simultaneously,it is presented how to determine the parameters of pressure–relief support. The pressure–relief support is successfully applied to the upper return airway of working face 2322 of Fenghuangshan...

According to the practical case of Fenghuangshan Mine,the destruction reason of support for previous roadway is analyzed. Combining the maintenance principle of pressure relief and support,the principle of pressure–relief support is interpreted with the consideration of wall rock creeping and pressure relief. Simultaneously,it is presented how to determine the parameters of pressure–relief support. The pressure–relief support is successfully applied to the upper return airway of working face 2322 of Fenghuangshan Mine. Compared with previous support,pressure relief support is of simple production process with lower maintenance costs,and it is very convenient to apply with significant social and economic benefits.

根据凤凰山煤矿现场实际,分析了以往巷道支护破坏原因,结合卸压和支护的维护原则,阐述围岩蠕变卸压支护方式的原理及卸压支护参数的确定,成功地在2322工作面上回风巷进行沿空掘巷卸压支护。试验结果表明,与以往使用过的支护方式相比,该方式的巷道变形小,安全状况明显好转,实现该巷在服务期限内无巷修工程,节约维护费用,减少优质煤炭资源的损失,提高矿井的经济效益。该支护方式工艺简单,维护费用低,便于推广,社会和经济效益显著。
