METHODICAL BASES OF THE EXTRACTION SECTION METHANE INFLOW DYNAMICS FORECAST WHEN WORIONG OUT THICK AND ADJACENT SEAMS WITH LONG PILLARS
In the article, mining and technological conditions of underground coal mining related to the development of thick and adjacent seams are considered. The gas-dynamic reaction of the massif to technological impact is conditioned by the coal seam being processed with modern technologies highly variable position, therefore its operational analysis is considerably complicated. Changes in mining and technological situations go beyond the organizational and technical measures envisaged by the current regulatory documents.The application of modern knowledge about the occurring geomechanical processes during the development of coal seams allows us to detail information about the massif properties and conditions that change under the influence of the shifting processes. The aim of the work was to refine the extraction section methane inflow dynamics forecasting method during the thick and adjacent seams development by long pillars in conditions of gas potential high variability and development of nonlinear geomechanical processes in the rock massif. The article results will serve as a basis for extraction section methane inflow dynamics control efficiency increasing and ensuring safe mining conditions.
