    High Efficient Rib Drill Stem for drilling in the soft coal seam and under the soft geographical condtion

     

    Rid drill stem belongs to the subdivision of geographical auger stem and includes single screw, double screw and triple screw type according to its blade types. It is also called geographical auger stem, low guide blade drill stem, auger stem, slot drill stem, groove drill stem, and body auger stem. Rib drill stem is made up of flat outside drill rod and screw blade with high wear resistant flat surface. by means of prestress winding and full automatic welding technology. The product , applying top-quality special geographical alloy steel pipe as its drill rod and applying 42CRMOA top-quality structural alloy steel as its rod joint, it  processed by means of advanced technology such as high pressure forming, vacuum quenching and tempering treatment, and friction welding. while drilling, it showshigh -strength mechanical capacity of geographical auger stem and excellent deslagging effect, with high deslagging speed and low revolving resistance. Owning to the large lead of screw blade and its plane structure design, the locking and damaging of drill tools have been lessened greatly when drilling in soft coal seam under the condition of the rock burst. This series of products have become the first chosen as the drilling tools in the soft coal stam and under the soft gelgraphical condition.
