近水平矿床留帮扩采方式的研究

Study of Remained-slope Mining in Surface Mines with a Flat-buried Deposit

本文针对我国几大露天矿区需扩大生产规模的现实，为降低新建露天矿的建设投资，提出了留帮扩采方式。以准格尔露天矿区为例，作者分析、对比了留帮扩采方案与重新拉沟方案的经济效果，提出了确定留帮扩采位置的一般原则。文中所得结论同样适合于其它类似矿区。

A new kind of mining method,remained-slope mining,is put forward in this paperin order to decrease the capital investment of a new surface mine,On the basis of the casestudy for Zhungeer surface coal minearea,the economic benefit of remained-slope mining is analysed,the general principles of selecting remained-slope location are discussed.The conclusions are also suitable for other similar coal fields.
