KQD70 60-80mm pneumatic electric blast hole drill rig for mining     Specification of pneumatic electric blast hole drill rig   1.High performance-all air driven down the hole drill 2.Simple structure and single dynamic 3.Adapt to any geological feature 4.Easy operating and move 5.Good noise reduction effect, reduce the pollut ion   Features of KQD70 pneumatic electric blast hole drill rig    1. The Ultimate combination of performance and economy.We can export all Kaishan DTH system .Kaishan DTH system delivers the highest-possible drilling performance at low running cost.Kaishan DTH used in varity heavy industry. 2. It is used to drill blasting holes like small to medium mining porjects,national defense projects , irrigation projects,road construction and ect. Our down the hole drill is edeal equipment for down -hole blasting . 3. Split type hudraulic power pack is the product that gains national patent. The power section and operation section are separate,therefore,when the drill works ,it is only  need the move the operation panel to realize multi-sopt work, which would lower the labor intensity and make the working life whole machine longer.   Advantages of KQD70 pneumatic electric blast hole drill rig A----Forward,turn,and the impact of all the compressed air as power,structure simple ,power,relocation facilities. B----In the single-top,double top,bearing-type three supporting structures to choose fom,can adapt to any geological features. C----Centralized control mechanism,easy to operate. D----Unique dual muffler,muffler effect, reducing environmental pollution.   Application of KQD70 pneumatic electric blast hole drill rig It is widely used in small and medium-sized mines,defense engineering,water conservancy,irrigation projects,road constrtction, blast hole drilling operations in Rock engineering, which is ideal machine to acheve hirarchial extraction and  medium deep-hole blasting.   Technology Details of KQD70 pneumatic electric blast hole drill rig
