Abstract

For efficient operation of a mining enterprise, the decisive role belongs to excavation areas forming volume of production and providing stability of support services. Taken engineering solutions to ensure permissible concentration of methane within working area depends on the nature of methane release (wall face, enclosing rocks, gob area, brokendown coal). Gas drainage operations from a working seam do not always provide reduction in methane emission to the required values and in these cases, effective and stable operation of an enterprise could be provided by the work of a shearer with an intensity that takes into account methane content in the developed seam, method of the working area preparation, ventilation scheme and vehicles characteristics. That is why modeling of broken-down coal transportation from the face, in order to determine the emitted methane, is an is an urgent task. The paper reviews issues of a mathematical model creation for coal transportation technological processes from the excavation area at the mine ‘Polysaevskaya’, JSC ‘SUEKKuzbass’.
