黑山铁矿Ⅰ号采场防排水方案

Waterproof and Drainage Scheme of Stope Ⅰ in Heishan Iron Mine

介绍了黑山铁矿Ⅰ号采场地形地质和水文地质特征。对露天采坑的防排水方案进行了技术经济比较,采取设置排水隧道的方案。针对地下开采分三期的情况,确定一期排水采用平硐自流,二期排水采用一段直排,对三期排水的接力排水和一段直排方案进行了技术经济比较,确定采用一段直排方式。

The paper introduces the geological and hydrogeological characteristics of stope I in Heishan Iron Mine. The waterproof and drainage scheme for open pit is analyzed from the technical and economic index, and the tunnel drainage scheme is taken. Due to the three phases＇underground mining, it is determined that the gravity tunnel drainage is adopted at first phase, the direct drainage is at second phase, and then the direct drainage is selected after comparing with the relayed drainage and the direct drainage from the technical and economic factors.
