Abstract: The analysis of mining and geological conditions of flat coal deposits of Kuznetskiy, Minusinskiy, Irkutskiy and other basins, where surface mining of coal is carried out, shows that in some cases it is possible and expedient to develop part of the reserves from opencast mining workings, which will allow to extract part of off-balance reserves. One of such technical devices is the complexes for deep mining of seams (CDMS, in English science literature – SHM), the technical state of which depends not only on economic indicators, but also on safety of service personnel.
Due to the fact that the experience of operation of such complexes is insignificant, these factors become extremely important when ensuring high manufacturability of repair. The necessity of scientific approach to the solution of this problem is also caused by the fact that in the repair service there is a lack of supply of repair documentation, tooling, diagnostic devices and special equipment by manufacturing plants.
It should be noted that the studies to assess the performance of CDMS at the enterprises to date have not been carried out, so the methodology for collecting and processing statistical information is absent. In this regard, it can be argued that the development and justification of methods to assess the technical condition of CDMS at mining enterprises is an urgent scientific task.
This article provides an overview of the application of complexes of deep seam mining and a brief analysis of literary sources devoted to this issue.
