利用梯子间延伸竖井的实践

Practice of Extending A Shaft Using Ladderway

对于生产矿山 ,利用梯子间延伸竖井 ,不影响矿山正常生产 ,且施工简便、掘进速度快、投资少。本文介绍了这种施工方案和各施工环节。

For an operating mine, the shaft was extended by using the ladderway which would not affect normal production on one hand, and offer such advantages as low capital expenditure, easy engineering and rapid excavation on the other. This paper presents the various engineering schemes and the construction procedures.
