Mining equipment

Pneumatic stowing machines of the "Titan-1" type are designed for mechanization of stowing operations during coal-bed preparatory mining workings adjacent to the mining faces. The units can be used in the preparatory mining workings of any shape, fixed with any support, with any undermining of lateral rocks.

THE UNIT IS MANUFACTURED IN TWO MODIFICATIONS:

  • The unit with one compressor and a stowing pipeline with a diameter of 170 mm (version "Titan-1M") is intended for use mainly during coal-bed preparatory mining workings adjacent to the mining faces, with the placement of rocks from blasting in the rock strip of the adjacent worked-out lava space.
  • The unit with two compressors and a stowing pipeline with a diameter of 195 mm (version "Titan-1M-01") is intended for use mainly with full or partial stowing of the worked-out space of the mining faces using imported rock with a strip width of up to 120m and a stowing volume of up to 175m3 per day

KS-2U/40, 2KS-2U/40 loading machines designed to mechanize the process of blasted rock loading into lifting vessels during the vertical shaft sinking.

The machines are used in combination with various sets of heading equipment used in the coal, mining and shale industries when drilling shafts in an explosive manner.

At the request of the customer, they are equipped with a mounted drilling rig BUKS-1U5, which allows to mechanize the process of drilling holes.

DESIGN FEATURES:

  • Loading machines are manufactured in two modifications:
    • one grab loader KS-2U/40 – for shafts 5.5, 6, 6.5, 7, 7.5, 8m in diameter;
    • two grab loader 2KS-2U/40 – for shafts 7, 7.5, 8, 8.5, 9 m in diameter.
  • The depth of shafts traversed by machines is not limited, as they are suspended directly from the tunneling shelf.
  • The machines are designed for wide use in mine construction as a means of increasing the average road-heading rate to 120 - 150 m per month.
  • One-grab loader assembly is performed within 15 – 20 hrs, disassembly – 8 – 10 hrs.
  • Loading machines can be efficiently used during various types of road-heading, but the main one is a combined way of road-heading with monolithic concrete support, which is mounted from the shaft face.
  • It is also possible to use a parallel method of road-heading in hard rocks and rocks of medium strength. In this case, a permanent fastening is erected from a tunneling shelf made of monolithic concrete.

BUKS-1U5 Unified drill unit is designed for mechanization of drilling of boreholes, cementation, degassing and exploration wells when sinking and deepening vertical shafts of mines with a diameter of 4.0 m to 9.0 m in the light in the coal, mining and shale industries.

DESIGN FEATURES:

  • The drilling rig consists of a removable part and components installed on a sinking platform and on a machine of the KS type (stationary part),
  • The removable part includes: drilling machines, manipulator, suspension, sliding column and pneumatic system.
  • The stationary part includes: a lead-in curve, equipment for cleaning boreholes and equipment for drilling cement wells.
  • The possibility of drilling machines to tilt in the vertical plane and turn in the horizontal plane allows you to change the distance between adjacent boreholes and drill a large number of holes from one position.
  • The use of spring jacks allows one driller to reliably and quickly expand the drilling machine at any slopes of the coal-beds (including steeply falling ones), rock hardness and roughness of the bottom of the hole.
  • The installation has a reduced noise level and water-air cleaning of boreholes, providing complete dust suppression and an increase in drilling speed.
