Issues of mining thick gently dipping seams with forced collapse of coal
Abstract
Improving the systems and methods for developing thick gently dipping seams is one of the most difficult and at the same time urgent tasks facing the coal mining industry at the present time. The most rational system for developing such seams is usually considered to be inclined layer mining with roof caving, which has become widespread in the industry. Engineering analysis shows that this system has a number of shortcomings. The issue of creating a rational system for developing thick gently dipping seams cannot be considered resolved. A rational system for developing thick gently dipping seams should provide for the exclusion of manually erected support in the working face, as well as the use of a large seam thickness. Among the possible solutions to this problem, the system for developing thick gently dipping seams with forced coal caving is particularly simple.
