摘　　要：以老挝钾盐矿提钾后的尾盐、母液为原料,以老挝当地产的白云石粉为凝结剂,考察了回填料的流动性、耐水性、耐候性、胶结性、抗渗性,并对回填料做XRD、能谱、电镜分析。结果表明白云石粉是适宜于老挝钾盐矿副产物回填的有效凝结剂。study was conducted on the fluidity, water resist- ance, weather ability, cementation and impermeability of backfill and analysis was made of backfill by XRD, energy spectrum and electron microscope taking tail salt and liquid potash after potassi- um extraction in a potash mine of Laos as raw material and dolo- mite powder from Laos as coagulant. The results showed that the dolomite powder is an effective coagulant for by-product backfill in the Lao potash mine.
