Abstract: The urgency of the discussed issue. In Russia, due to low efficiency, all mines in the Kuznetsky, Kizelovsky, Pechersky, Donetsky basins and Sakhalin fields, developing steep and steeply inclined coal seams, were closed. This is due to high labor costs, low productivity, complexity of operation and the need for the constant presence of people at the face to perform complex technological operations and control rock pressure.
The main aim of the study. Creation of effective and safe technologies for the development of thick steep and steeply inclined coal seams without the constant presence of people at the working face on the basis of robotic equipment complexes.
The methods used in the study. Generalization and analysis of existing technologies for the development of steep and steeply inclined coal seams.
The results. For Russia, the development of deposits with hard-to-recover coal reserves is a promising area, primarily with thick steep and steeply inclined seams. The technology of coal mining from thick steep and steeply inclined seams without the constant presence of people at the working face can be carried out by cutting the extraction field using the turn-around rooms of the shearer, which allows the use of mobile mechanization equipment in the mining process. Technological schemes for the preparation and development of the extraction field have been developed, which allow the use of mobile means of mechanization of mining operations with elements of robotization and ensure the release of coal from the overlying strata.
