摘　　要：河南省汝阳县东沟超大型钼矿北部外围绿竹坪铅锌矿床是近年来发现并探明的构造蚀变岩型中温热液矿床。矿床的开采技术条件:水文地质,不存在强含水层,大气降水为开采坑道的主要充水来源,在正常情况下影响小;工程地质,断裂破碎带及构造角砾岩易发生冒顶与片帮,火山岩坑道则相对完整稳固,对开采影响不大;环境地质,滑坡、崩塌、地裂、塌陷等方面均属简单型,对矿床开采无大影响。Lvzhuping lead-zinc deposit in the northern periphery of Donggou ultra-large molybdenum deposit in Ruyang county, Henan province is a medium-temperature hydrothermal deposit of tectonic alteration rock type discovered and proved in recent years. Technical conditions for mining the deposit: hydrogeology, there is no strong aquifer, and atmospheric precipitation is the main source of water filling in the mining tunnel, which has little influence under normal conditions;Engineering geology, fracture zone and tectonic breccia are prone to roof and sheet, volcanic tunnel is relatively complete and stable, and has little influence on mining;Environmental geology, landslide, collapse, ground fissure, collapse and other aspects are simple, no major impact on the deposit mining.
