Role of unloading and filtration of gas in the development of main cracks in coal seams

The development of main cracks in coal seams due to rapid unloading is analyzed using the methods of theoretical physics. A fracture criterion and a criterion for the time to fracture of an area at the edge of a coal seam are obtained.
