| Summary: | Relevance of the study is important because of often methane explosions in coal mines. It obliges us to change the approach to extraction of coal and methane gas. The main aim of the study: The increased natural gas-bearing of coal beds and low effectiveness of the preliminary degassing today are the most urgent problems to ensure safe coal production. The large volume of drilling at various types of degassing increases coal mining cost and does not permit to reduce the natural gas-bearing to the desired level in a short period of time. The methods used in the study: The integrated approach to allocation scheme of exploration holes at the stage of exploration project will allow using these holes for further degassing of coal beds and methane production on industrial scale. The results: Application of exploration holes as additional holes for degassing coal beds in advance will allow more effective reduction of natural gas-bearing to the start of coal mining. The comparative analysis of exploration network density influence with the requirements of the "Guidelines on the application of classification and probable reserves of the deposits of solid minerals, resources of coal and oil shale" and coal bed radius of stimulation achieved for the moment confirms the need for the possible use of these holes as the degassing ones. The advance degassing of coal beds is crucial to ensure coal and methane safe production on industrial scale. |
