Abstract: The issues of improving degassing operations are considered. The main methods of degassing that ensure the integrated development of resources are identified, and measures to improve degassing are proposed. The results of a review of R&D and publications for the period 2010-2024 in Russia and the USA are presented. It is shown that the restructuring of the coal industry has led to a drastic increase in the technical and economic indicators of coal mining and, as a result, increased feedback in the technology – environment system; The use of high-performance equipment, which ensures an increase in labor productivity and leads to a decrease in the number of jobs, leads to a significant increase in safety requirements. This is mainly determined by a decrease in the reserve level when planning mining and preparatory work. One of the main problems of the current stage of development of coal mining technology in our country is the aggravation of the contradiction between the pace of preparatory and cleaning operations, which complicates the use of pre-degassing of the developed formations. The reasons for the low level of methane safety are given, for example, such as the continuing deterioration of mining and geological conditions of mining reserves, primarily associated with the deepening of mining operations. At high loads, sources that previously had not received much attention, such as satellites under development or a coal seam under development, are becoming increasingly important. The directions of improvement of degassing methods are noted. At modern depths of development in formation conditions, the gas of coal deposits has conditions exceeding the quality of gas from gas fields, primarily due to the absence of sulfur compounds. Effective extraction of conditioned methane is possible only if the permeability of the coal seam is increased, which can be achieved either by affecting the formation or by mining methods.

Key words: degassing effectiveness parameters improvement control methane emission rate forecast trends
