This article discusses the issues of ensuring the safe conduct of mining operations in coal mines. Ensuring the safety of coal industry workers is an urgent problem today. The gas content of the layers increases with the depth of their occurrence and is a deterrent factor in the extraction of minerals. Sudden methane emissions can provoke a large number of human casualties, financial losses, and other consequences. In recent years alone, such accidents have claimed more than 157 human lives in the mines of the Karaganda coal basin. However, by solving this important problem, you can get associated gas. It is not easy to reduce the gas content using existing degassing technologies. The formations have almost zero gas permeability and low gas output at the current depths of their development. That is why it is necessary to have an impact on the coal seam as early as possible in order to ensure the release of methane. This process will make it possible to obtain associated gas, which can be used for the needs of industry or the national economy. As a result, reducing the gas content of coal seams will reduce the risks of mining operations and increase labor safety.

“…Methods and materials. Schemes and methods of degassing for workings (preliminary degassing of the formation, degassing of under-and overworked satellite layers and degassing of the mined-out space) and preparatory faces (preliminary degassing of the formation, degassing of barrier wells during drilling, degassing of bends and boreholes) are selected based on gas abundance site (working) and degassing efficiency [4]. First of all, degassing measures are applied at the source with the greatest gas release.…”

The article presents the most effective degassing methods when carrying out preparatory workings for coal, provides an analysis of the effectiveness of each degassing method, the conditions for their use to reduce the gas content of the formation, increase the pace of preparatory workings and the safety of mining operations. To reduce the gas content of workings carried out in a coal seam, preliminary degassing of the seam can be used, carried out before the working, or degassing of the coal mass during the working period. The most effective way to reduce methane emission into development workings is preliminary degassing of the coal mass with a period of gas capture before the start of tunneling work in the prepared area of at least 12 months.
