    Triangular drill for geological exploration, water prospecting and gas release in underground coal mine

     

    With 20 years experience for the research, our production technology has been promoted perfect and our stem has been produced with the merits of top quality and stable operation. Triangular drill stem for mine underground drilling is also named as triangular drill stem or triangle drill stem, anti-collapse drill stem, and anti-locking drill stem. The joints of taper trasition and threaded, triangular, square or hexagon type are welded by means of friction welding technology to the triangular arc drill stem for the underground drilling. The application range: geographical exploration, water prospecting, and gas release,.

    in course of drilling work of trianular drill rod, three gaps are formed between the rod and the wall of the hole, enlarging the passage of dedusting and gas drainage.In the rotary drilling, the redundant boring mud is constantly pained on the wall of the hole, making it solidified and lessening the locking and damaging of drill tools caused by hole collapse.

    Triangular drill stem has the merits of reasonable design, safety, reliability, high deslagging efficiency, great drilling depth, high ratio of finishing hole, etc.
