1.Advantages of construction method

Use: DTH Hammer drilling is a good way to drill through cave formation and avoid stuck problem

Cave: When encountering caves, drill bit inclines to the cave. The stabilizer ensures the hole straightness

Bit stuck;One reason is cave encounter, the drill bit deviates, and the entire set of drilling tools inclines in the hole. The other, is hole collapse. A large number of rock or clay catch the drill pipe, resulting in bit stuck. Steel casing and stabilizer can resolve this problem.
