Abstract:The regularity of strata pressure around coal face in Queen seam of PVK colliery in India is analyzed. It has shown that the pressure arch,rather than the beam or plate,can be formed under the shallow-buried and very loose roof. When coal face reaches a certain distance,the pressure arch is destroyed and the initial weighting occurs. When the arch vault is close to ground surface,the rock mass of the key structure inside pressure arch is destroyed and more fierce pressure occurs. Subsequently,the rock mass of the subordinate structure outside the pressure arch is destroyed followed by surface subsidence. The periodic destruction and advancement of arch structure cause the occurrence of periodic pressure. The result reasonably explains the phenomenon that the behavior of ground pressure is very strong even under the very loose roof and can be referred for further studies in similar conditions.
