Geological factors of gassing of the east inclined longwall # 3 of m ₃ bed at O.F. Zasiadko mine

摘要

The paper deals with the fact that gassing of the East inclined longwall (EIL) # 3 of the m_(3)bed at the ?O.F. Zasiadko mine? are caused by a combination of mining-geological conditions. The main geological factor is the presence of a synclinal fold, characterized by increased fracturing. The map construction of local structures, the use of gravity data and seismological observations allow to effectively isolate gas-saturated zones and, therefore, correct degassing projects and parameters of ways to prepare workings.
