Study on Acid Rock Waste Dumps Vegetation Pilot Trials at Dexing Copper Mine
Soil reconstruction and improvement trials and vegetation experiment is carried out at Shuilong shan acid rock waste dumps at Dexing Copper Mine in China.pH value,Cu2+,Pb2+,Zn2+,etc.concentration in acid rock drainage (ARD) is also monitored every month since 2005.The results of experiment show that:Lime and topsoil stripped from open-pit is appropriated soil improvement material.Full cover soil improvement method is suitable for flat area,contour soil improvement method and hole soil improvement method is appropriate for slope area.The optimal plant species is ligustrum lucidum Ait,Lespedeza bicolor,Paspalum notatum,Vetiveria zizanioides,Eragrostis pilos and Neyraudia reynaudian.It is the best for Arbor,shrub and grass to be arranged in pairs or groups in order to remold optimal landscape.Pilot sites,covering 3ha,is established.Vegetation coverage reaches 90% in platform area,40% in slope area.pH value in ARD increased slightly,Cu2+,Pb2+ concentration in ARD decreased,Zn2+concentration in ARD decreased and varied slightly.
