Study on the influence of close range coal seam mining relationship on the deformation law of surrounding rock in lower roadway

When the mining relationship between the upper coal seam working face and the lower coal seam roadway in the close distance coal seam changes, the deformation and instability mechanism of the surrounding rock of the roadway will be more complicated. At present, there is little research on the dynami...
