Abstract: Hard coal is one of the most important solid minerals. The possession of large mineral reserves is one of the signs of the importance of companies, industries and even the independence of countries. Coal reserves are non-renewable resources and, therefore, the strategy for their extraction and exploitation must be prudent. Practically any extraction of coal reserves is accompanied by the formation of pillars of various purposes, shapes and sizes within the mine fields, with their variety of conditions of their occurrence. Some pillars fulfil long-term special, including protective functions and cannot be extracted. Some of pillars, after they fulfil special functions, can be worked out using special technologies and technical means. The variety of pillar parameters and conditions of their occurrence implies the necessity to develop special technologies and appropriate technical means for their mining according to groups of conditions with close values of their parameters. The article analyses technologies and proposes unified excavation modules for pillar extraction, formulates requirements to the structure, to the technology of their operation and to the technical equipment of unified excavation modules.
