Abstract
The paper proposes a method for predicting the degassing time based on pressure measurements in the coal seam at the initial stage of the process. The proposed method of forecasting is substantiated with the help of mathematical modeling. To carry out mathemat- ical modeling, it was necessary to solve a two-dimensional parabolic equation in a perforated domain. A numerical method for solving this problem is proposed.
期刊介绍：
Eurasian Journal of Mathematical and Computer Applications (EJMCA) publishes carefully selected original research papers in all areas of Applied mathematics first of all from Europe and Asia. However papers by mathematicians from other continents are also welcome. From time to time Eurasian Journal of Mathematical and Computer Applications (EJMCA) will also publish survey papers. Eurasian Mathematical Journal publishes 4 issues in a year. A working language of the journal is English. Main topics are: - Mathematical methods and modeling in mechanics, mining, biology, geophysics, electrodynamics, acoustics, industry. - Inverse problems of mathematical physics: theory and computational approaches. - Medical and industry tomography. - Computer applications: distributed information systems, decision-making systems, embedded systems, information security, graphics.
