大坡度下山巷道综掘快速施工技术的研究与应用

Research and application of rapid excavation technology for large slope down roadway

针对如何实现大坡度下山巷道综掘快速施工,福城煤矿充分利用现场实践经验,通过对综掘机退机、下山迎头积水、下山行人等关键环节采取措施,解决了大坡度下山巷道综掘快速施工的关键问题,提高了掘进速度,取得了显著的经济与社会效益。

In order to achieve the rapid construction of the dip with large slope, Fucheng coal mine make full use of practical experience, take reasonable measures to solve the problems, such as withdrawing the roadheader, the ponding in the extracting face, and the pedestrians difficulty, well solve the key problem of fast construction of the dip with large slope, improve the driving speed, and has achieved remarkable results.
