Deep Hole Rapid Sampling Device  SDQ-73

Product Application

      Enables rapid sampling and fixed-point sampling during coal seam drilling operations.

Technical Parameters

     Drill Pipe: Diameter 73mm;

    Drill Bit: Diameter 94mm;

    Sampling Speed: >500 g/min;

    Rated Working Air Pressure: Above 0.55Mpa;

    Sampling Depth: 0～100m (varies depending on geological conditions)

       The deep hole fixed-point rapid sampling device meets the requirement for achieving fixed-point rapid sampling during coal seam drilling. This instrument utilizes advanced aerospace jet technology and multi-stage ejection technology, allowing sampling without withdrawing the drill pipe. It can achieve rapid fixed-point sampling at any point within 100m or a larger range in the coal seam within 5 minutes, complying with the GB/T23250 "Direct Determination Method of Coal Seam Gas Content Underground" requirement of "sampling time less than 5 minutes and fixed-point sampling".
