Abstract
The process of underground mining is one of the most complex and hazardous activities. In order tomaintain the continuity and efficiency of this process, it is necessary to take measures to reduce thishazard. The paper addresses this issue by presenting a developed methodology for using model studiesand numerical simulations to support the process of monitoring methane hazards. Its basis is the de-veloped model of the region of underground mining exploitation along with the ventilation phenomenaoccurring in it. To develop it, the ANSYS Fluent program was used, based on the finite volume methodclassified as computational fluid mechanics. The model reflects both the geometries and physical andchemical phenomena occurring in the studied area, as well as the auxiliary ventilation equipment usedduring operation. The research was conducted for two variants of methane emissions from goaf zones,the first of which concerned the actual state of the mining area, and the second of which concernedincreased methane emissions from these goaf zones. The purpose of the study was to determine thedistribution of methane concentrations in the most dangerous part of the studied area, which is theintersection of the longwall and the tailgate, as well as the distribution of ventilation air flow velocitiesaffecting them. The studies for both variants made it possible to determine places particularly exposedto the occurrence of dangerous concentrations of methane in this region. The methodology developedrepresent a new approach to studying the impact of methane emissions from goaf zones into mineworkings.
