 The study examined the relationship between mining fissures and rock-beam structure in shallow coal seams. It was found that the types of mining fissures in the overlying strata of key strata were up and down i and 1 to 2 mining fissures, with height to 44.38 meters and 98.35 meters, respectively. The key block rotation caused the mining fissures to go through five dynamic activation cycles. A formula for calculating the fissure activation cycle was developed, and the rock-breaking angle, mining fracture lag distance, and fissure penetration discriminate were also measured and verified.
