Purpose

The machine is intended to carry out mining extraction of thin and very thin (0.8-0.9 m thick) stratified coal deposits without people having to be present, in a goaf (worked-out area) without the need to support it.

Field of application

Work at thin and very thin layers of stratified deposits of mineral resources.

Advantages

The BZM-1M1 drill setting machine is a remote controlled device based on a tracked self-propelled chassis intended to carry out drilling of non-circular section holes. The BZM-1M1 is fitted with dust-and-gas condition normalising devices, a system to control the attitude of the machine and its tool relatively to the stratum being exploited, an automated system to control the modes of drill/auger-type mining extraction of mineral resources and stowing of rock into the drilled-out space.

The device is used together with technological equipment to carry out delivery, building up, storing of the sections of the augur structure, mechanisation of installation work and transportation of mined mineral resources.

The procedures of machine use make it possible to:

  • increase labour productivity by 2 to 3 times if compared with ordinary cutter-loaders which operate by cutting the enclosing rock;
  • reduce the hard physical labour to minimum; in so doing, the safety and comfort level will be increased;
  • reduce the specific amount of metal in the equipment, power consumption and practically reduce to zero the need for timber consumption.
