<p>Coal mining induces rock fracture and movement into the excavated space and alters the stress environment of the surrounding rocks. How to characterize mine pressure and control strata is fundamental to underground coal exploitation. However, few research concerns the relationship between overburden structure and dynamic disasters, spatiotemporal evolution of mining induced stress, causing mechanism, and joint warning model for dynamic disasters. To fill these gaps, this study proposes the use of the difference in support resistance to continuously detect the overburden stress of working faces. The concept of the dynamic pressure differential index of support (DPDIS) is introduced. A theoretical model for the DPDIS is constructed. Then the spatial evolution of DPDIS is simulated. A warning model for dynamic disasters based on the DPDIS is developed and applied in a coal mine. To well perfect the warning model, microseismic monitoring is integrated. The combination of DPDIS and microseismic monitoring could perfectly detect the rock fracture and near-field stress in the entire mining area and increase the warning reliability to dynamic disasters.</p>
