Abstract: Aiming at the problems of severe ground pressure behavior during final mining and poor roof maintenance effect in B10 coal face of Shajihai Coal Mine, a systematic study was carried out by means of field measurement, numerical simulation and theoretical analysis. The roof structure and crack development of the withdrawal channel were mastered through the roof drilling peep. The FLAC3D numerical model of withdrawal channel was established, and the stress distribution and plastic zone evolution law of surrounding rock in withdrawal space were compared and analyzed under the two schemes of pre-excavation single withdrawal channel and self-excavation withdrawal channel. The roof hierarchical control principle of large fracture depth in withdrawal space was proposed, and a roof hierarchical control method dominated by medium and long anchor cables was formed. Based on this, the roof support scheme design of withdrawal channel in B1003W03 working face and the surface displacement monitoring of surrounding rock were carried out. The results show that compared with the layout of pre-excavation single withdrawal channel, the supporting stress distribution and plastic failure range of surrounding rock in the withdrawal space under the form of self-excavation withdrawal channel have been improved. The design of support scheme can effectively control the roof of shallow-middle-deep layer. The monitoring data show that the withdrawal channel deformation is small and the support effect is good.
