Abstract. The paper deals with the fact that gassing of the East inclined longwall (EIL) # 3 of the m3 coal bed at Public Joint Stock Company «Mine named after O.F. Zasiadka» are caused by a combination of mining-geological conditions.

The purpose of the paper is to determine the main geological factors that influenced on the gassing of Eastern inclined longwall # 3 of the m3 bed located at the «Mine named after O.F. Zasiadka» field.

To achieve this purpose, the complex research was conducted. This complex includes the study and generalization of actual geological material, the results of research by geophysical methods: gravity prospecting and seismological monitoring carried out on the «Mine named after O.F. Zasiadka» field. We used an analytical method for selecting the positive local structures (the trend-analysis of the surface of coal beds and sandstones). It is explained in complete detail in paper.

To determine the distribution of fracturing in the rock mass in the process of mining, the results of seismological observations carried out at the «Mine named after O.F. Zasiadka» field were used, applying the Polish seismic system "ARAMIS". This system records the seismic events resulting from cracking, fixes the magnitude of their energy and determines the coordinates of the origin. Based on the results of observations, a database was compiled, which was used to study the seismic regime of the mine, selection of fracture zones and the dynamics of their development.

Seismological studies have shown that the recorded seismic events in the massif form zones with the same orientation as the gravimetric anomalies, and are confined to negative gravitational anomalies, that is, to the zones of weakened rocks.

Thus, gassing of the EIL # 3 of the m3 coal bed at the «Mine named after O.F. Zasiadka» caused by a combination of mining-geological conditions. The main geological factor is the presence of a synclinal fold, characterized by increased fracturing. Mapping of local structures and the use of seismological observations make it possible to effectively identify gas-saturated zones and correct degassing projects and parameters of ways to prepare workings.

Keywords: gas saturated zone, local structure seismological monitoring, fracture distribution.
