Diamond drill tips Introduction

Diamond Drilling  is one burning most prone to accidents , should be strictly precautionary measures . Improve the stability of the drilling process drilling , drilling technology due to improper parameter selection , hole deviation serious drill grading unreasonable , impact of factors such as oversized drilling , the drill will produce different levels of vibration . The inner diameter of the inner diameter diamond drill retainer and freedom must be reasonable fit. Although we can not eliminate all vibrations , but these take appropriate preventive measures are available for improvement. Diamond drill means to prevent burning burning diamond drill during drilling , improper operation or hole situation is complex, resulting in diamond drill was burned , can no longer short.

    Burned by the diamond drill drill Xuan scrap , drill costs surge ; severe, bit matrix melt and rock dust and residual core sintered together , or even burned together along with the core tube of 1m more serious accident, resulting in forced final hole or scrapped. Drilling process, does not allow any poppet drill , opening and closing the car to a smooth , drill press , pump volume should be uniform. Therefore , before each drill , pay attention to test with the size of the drill bit size and retainer . Airport should be prepared only 2-3 kinds inch retainer for matching. In order to ensure smooth over the broken core can smoothly into the tube, the wall can be painted a suitable grease or spray plastic , chrome -ming . Swelling , joint development and so easy to block formations should be smaller diameter , reinforcing good drill to make the core more smoothly into the tube. Kahuang freedom inside diameter is too large, or not on the card is not strong to take the core , resulting in half- off or excessive residual core ; Kahuang freedom inside diameter is too small, could easily lead to core plug. Should be used in single-action double pipe joint development drilling , crushing, dip a large rock layer should design special coring tool . Take appropriate damping measures to reduce the vibration caused by rocks , broken heart blockage caused by mining . Malignant burn drill will cause sticking accidents, often accompanied by a drilling bent.
