摘要
通过全面分析影响地浸钻孔涌水量的地质、水文地质及水岩作用过程等因素,从理论上剖析提高地浸钻孔涌水量的方法;通过改善钻孔施工工艺等措施保持和提高矿层的天然渗透性;结合NZ砂岩铀矿床地浸采铀中采取提高钻孔涌水量技术措施的实践,分析各种提高钻孔涌水量技术的适用条件和实际效果,并提出提高地浸钻孔涌水量的改进建议。
Some factors influencing the discharge of in-situ leaching drillholes, including geology, hydrology and water-rock interaction, are discussed systemically, and the measures to reinforce the discharge of in-situ leaching drillholes are analyzed theoretically. It is considered that the original permeability of ore-bearing layer can he kept and enhanced by improving the construction technique of drillholes. Technical measures taken to reinforce the discharge of drillholes in in-situ leaching of NZ sandstone uranium deposit are introduced, various application conditions to reinforce the discharge of drillholes and actual effects are analyzed, and improvement suggestions are put forward, too.
