3 Drilling Methods To Consider For Soil And Rock Testing
Aug 06, 2018· Drilling Methods 3 – Mud Rotary The mud rotary method of drilling uses a drill bit that is mounted on the end of a drill rod and is advanced by the rapid rotation of the bit The cuttings are removed by pumping drilling fluid (water or water mixed with bentonite or other fluid enhancers) down through the drill rods and bit and up the annulusOne such method is the directional core drilling method that will be discussed in this section Directional Core Drilling Equipment In the 1980s, a Norwegian firm Devico AS developed the first directional core barrelSince then constant research and development have made it a popular tool for conducting a geotechnical investigationThe Directional Core Drilling Method: It's Importance to
