地下矿山开采对引滦入津输水隧洞影响分析

摘要

In order to keep abreast of the Underground Mining Influencing on Tunnel Diverting Luanhe River to Tianjm and ensure safety of water conveyance tunnel during iron mining, this article analyse the current situation of undergroud mining and the geological condition of surrounding area. By mining subsidence and the impact of blasting vibration analysis, Determining the protected boundary of water conveyance tunnel in mining.%为了掌握地下矿山开采对引滦入津输水隧洞的影响情况,确保隧洞在周边铁矿开采过程中能够安全正常使用,本文针对隧洞两侧矿山开采现状和区域地质条件,从矿山开采沉陷和爆破震动影响两个方面进行分析,综合确定了隧洞两侧的开采保护边界.
