Abstract: Introduction. The article contains information on the development of technology for the development of man - made deposits represented by the tailings of mining and processing of coal mines in the coal - mining regions of the country. The development of the resources of man - made deposits will stimulate the integrated development of the mining region and increase its economic attractiveness. Research methods include the analysis of best practices, literature sources, analysis of the results of field and remote observations, laboratory experiments and mathematical modeling. The results of the research. The experience of borehole excavation is generalized and is widely used in the underground and open - pit mining of coal deposits and tailings dumps, as well as sand deposits. Information is provided on a new technology for mining man - made deposits using a drilling rig for destruction and delivery of raw materials by rotating and feeding a drilling screw shaft. Calculation models are given to determine the parameters of mining a man - made deposit by a drilling rig using conveyor transport. The organizational factors of using the machine during the shift and technological factors are detailed, taking into account the conditions of its operation differentially in a specific situation. The issues of geomechanics of the drilling process with the calculation of the size of the natural collapse arch above the borehole and the natural collapse arch are considered. The advantages of auger mining of technogenic deposits are substantiated in comparison with existing technologies and an assessment of the prospects for using this technology in the development of technogenic deposits of coal - mining regions is given. Resume. The proposed technology for the development of man - made deposits has a promising use and is provided by the use of continuous operation technology, cost minimization and the possibility of selective extraction of raw materials and is recommended for the development of solid minerals at mining enterprises
