With the increase of mining intensity, mining causes significant dynamic disturbance and dynamic disasters, which have exerted a great influence on the safety and high-efficiency of production. This article based on the study of the displacement tendency of the rock masses on or under fractured face of the key layer, deduces the vertical stress calculation formula of the rock mass under the fractured face which indicates that the vertical stress is correlative with the length of fault block in key layer, the depth of key layer, the distance between key layer and mining coal seam, the equivalent elastic modulus of coal stratum underlying the key layer and so on; And then by numerical simulation, it studies the dynamic disturbance effect on front coal-rock masses as the key layer fractures which shows that dynamic disturbance effect caused by high intensity mining is relatively conspicuous on the fractured stratum (the key layer), the stratum under the fractured one and the stratum in the advancing direction of working face; As for the stratum on the fractured one (the key layer),the dynamic disturbance effect becomes less conspicuous as they grow farther away from the fractured one.
