Study on the Synchronous Instability Mechanism of the Coal Wall and Direct Roof of High Soft Coal Seam
The advanced mining stress on a large working face can easily lead to the failure of the roof and coal mass; coal wall spalling and roof caving occur. The degree of coal wall failure and the depth of the plastic fracture zone are closely related to the advanced mining stress. The mechanical analysis...
