• The N00 mining approach significantly reduces entry roof settlement compared to the conventional 121 approach, enhancing entry stability and safety.
• By incorporating roof cutting and NPR cable support, the N00 approach optimizes the mining and entry formation process, reducing the settlement phase and improving roof steadiness.
• The N00 approach lowers hydraulic support pressure in the mining panel, mitigating severe mining pressure manifestations and improving operational safety.
• Field monitoring confirms the effectiveness of the N00 approach in protecting both entries and mining panels, offering a promising alternative for coal mining.
