Application Summary AI generated
This standard specifies the technical requirements and procedures for using protective seam mining as a method to prevent rock bursts in underground coal mines. It is applied during the planning and execution of mining operations in deep or high-stress coal seams where the overlying or underlying protective layer is extracted first to relieve stress. The standard is used by mining engineers and safety personnel to design and implement protective seam extraction strategies that reduce the risk of dynamic rock failures.
