FORECASTING THE TIME OF COAL DEGASSING WHEN USING THE DATA OF THE INITIAL STAGE OF ITS DEGASSING PROCESS

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.
