中关铁矿矿坑水回灌试验研究

摘要

The paper plans to adopt recharging technology to conduct underground water treatment for Zhongguan iron ore,and do recharging test study. According to the results of recharging test,and through the methods of analysis on stratum inj ectivity ability and recharging ability of recharging area,etc.,the final recharging area selects the main recharging stratum that is the strong runoff zone of underground water 200m to the east of grouting curtain. This area’s elevation is -179.0~-300 m with strata cranny karst development,and strong water permeability. It has strong recharging ability.%拟采用回灌技术对中关铁矿进行地下水治理，并进行回灌试验研究。根据回灌试验试验结果，通过地层吸水能力分析、回灌区域回灌能力分析等手段，最终回灌区域选择注浆帷幕以东200 m 处地下水强径流带区域，标高-179.0~-300 m地层裂隙岩溶发育，透水性强，具有很强的回灌能力，可作为后期回灌工程的主回灌层。
