下石节煤矿综采面回撤通道支护参数优化实践

Optimization of supporting parameters for equipment removing gateway in fully mechanized mining face of Xiashijie coal mine

总结了下石节煤矿2302、221采面回撤通道原有的支护参数及存在问题,提出了223采面回撤通道优化后的支护参数,实施后观测结果表明下石节煤矿223采面回撤通道支护参数优化是成功的,为未来采面回撤通道支护参数的确定提供了依据。

By analyzing the existing support parameters and existing problems of equipment removing gateways in No. 2302 and No. 221 mining face of Xiashijie coal mine,supporting parameters of equipment removing gateways in No. 223 mining face were optimized. Application shows that the optimized supporting parameters can meet the need of gateway supporting in No. 223 mining face,which can provide the basis for the supporting parameters determination of equipment removing gateways in the future.
