In the new type sonic environmental drilling rig, ultrahigh frequency vibration drilling method is used. This method doesn’t need mud and without pollution for sample. It can obtains nondisturbed statra sample rapidly and continuously,it can provide highquality statra sample for exploring and has obvious advantage than traditional investigation drill rig. The rig structure, the design of sonic drill head and hydraulic system, the mensuration and good effect of tailing dam investigation were introduced.The sonic drill rig has great value for enviromental geology investigation, tailings reservoir prospecting, placer gold and water solution mineral exploration, geophysical prospecting blasting hole.
