Introduction:
The near-trunk yard is one of the most responsible, complex and expensive complexes of the mine. Near-shaft yards of mines and mines are a complex of workings and chambers that connect mine shafts with all other workings and ensure the functioning and life of underground mining. As a rule, the service life of the near-shaft yard is calculated for the entire life of the mine, so the layout of the workings, the choice of the type of support, technological and transport interchanges are very important, and the duration of the construction of the mining enterprise as a whole depends on the choice of methods and methods for carrying out the near-shaft yard.
