Conclusions

  1. 1.

    Experience at pit 51 has shown that effective ventilation can be organized for extracting thick deposits by a room and pillar system.

     
  2. 2.

    Effective removal of dust and toxic gases from the working faces is ensured by a minimum amount of air, provided that the face is of a longwall pattern.

     
  3. 3.

    In the mining of thick deposits in several stopes the fact that the number of ventilation flows is not in proportion to the number of working zones and absence of means to distribute the air between these zones impairs the ventilating system.

     
  4. 4.

    Excessive enlargement of the air-feed working sections (16–20 m2 and upwards) makes for plane (extended) velocity profiles in the working zones and this reduces the effectiveness of dust removal.

     
  5. 5.

    The working area can be reliably insulated by concrete bulkheads 0.3 m thick for a working section up to 10 m2 and up to 0.5 m for greater are as. Where there is no cut, the bulkhead should be reinforced with grouted rods to a depth of 1 m around the perimeter of the working.
