The stope space, after mining an extra-thick coal seam with hard roofs, is large, and its law of mining pressure is complex. The mechanism of strong mine pressure action for this stope is unclear, and there is a lack of multi-point control technology

Abstract The coal production exploited from extra‐thick coal seams accounts for 45% of China's total coal production. With large coal output, the extra‐thick coal seams require that the chamber section be more than 100 m2. In case of parting (the

The fracturing of hard roofs in different layers would result in complex ground pressure on the working face, such as supports collapsed and severe roadway deformation. However, the mechanism of the ground pressure induced by hard roof fracturing in

When mining extra-thick coal seams, the main cause of strong ground pressure are the high-level thick and hard strata, but as yet there is no active and effective control technology. This paper proposes the method of subjecting hard roofs to ground f

Ground fracturing is a new and effective method for controlling high-level hard roofs. In underground coal-seam mining, the maximum principal stress is horizontal stress, along with the direction of hydraulic fracture propagation. In this study, the

In order to effectively predict and control the rib spalling and roof leakage, it is necessary to reveal the deformation and failure mechanism of the chamber and propose the corresponding surrounding rock control technology. Based on uniaxial compres
