In the article, the authors talk about ways to improve the quality of core sampling from methane coal seams in the Kuznetsk coal basin. Core sampling is carried out at the exploration wells of Naryksko-Ostashinskaya square. Methane extraction is carried out to remove gas from coal seams. Moreover, gas can be used as unconventional energy sources. Thus, safety at coal mining facilities increases, and we receive additional income for the sale of gas to end consumers. To develop a technology for extracting gas from coal seams, core sampling is carried out, and the results obtained are analyzed. Further adjustments are made to the extraction technology, the selection of technological equipment is carried out. Drilling is carried out in the following sequence: initially, a vertical well with core sampling is performed, and then a multi-hole well is drilled with a large face deviation. As a result of experimental core selection and development of improved equipment, core removal was increased from 77% to 100%.
Key words: core sampling / drilling technology / coal seams
