摘　　要：钾盐是中国紧缺的战略性矿产资源之一,随着中国企业投资老挝钾盐的生产,经过近年发展,部分矿山已由实验性项目或验证性项目向规模化、规范化生产过渡。地下固体钾盐矿开发需克服采空区治理、尾矿与卤水处置等技术瓶颈。尾盐通常采用推存的方式处置,在老挝热带、亚热带季风气候条件下,面临较大的环保风险。本文介绍老挝某钾盐矿对掘采机条带充填法采矿、水力尾盐充填技术的实践与探索,简要阐述固体钾盐矿水力尾盐充填技术工艺特点,为同类矿山开采提供借鉴。Sylvite mine is a kind of scarce strategic mineral resources of China.Chinese companies invest in Laos sylvite mine,with recent developments,some mines have transitioned from experimental or verification projects to large-scale,standardized production.The development of underground sylvite mine needs to overcome technical bottlenecks,such as managing mine goaf,disposing tailings and brine.Tailings usually disposed by push storage.Laos has a tropical subtropical monsoon climate.Sylvite mine facing huge environmental risks.This article introduces the application of hydraulic filling in Laos potassium mine,and explains technical characteristics,provideds a reference for similar mines.
