摘要
矾山磷矿是华北地区大型磷矿生产矿山,为第四系孔隙水及基岩裂隙水充水矿区。本文在分析地质采矿条件基础上,对采空塌陷、地裂缝地质灾害和含水层破坏的成因进行了分析与评估,并提出了相应的防治措施。
Fanshan phosphate mine,located at the Quaternary pore water and fissure water filling area,is a large-scale productive mine in North China.Based on analysis of the geological and mining condition,formation of mined-out collapse,ground fissure and aquifer breakage is evaluated.As a result,some prevention and control measures are put forward.
