Application Summary AI generated

This standard specifies the technical requirements and procedures for using hydraulic fracturing to prevent rock bursts in coal mines. It is applied to the pre-splitting or weakening of hard, thick roof strata above coal seams to reduce stress concentration and dynamic hazards. The standard is used by mining engineers and safety personnel for designing, implementing, and evaluating roof fracturing operations in underground coal mining.
