Abstract Tangshan Mine entered deep mining, where the physical and mechanical environment, damage characteristics of coal and rock bodies, and coal body organization were different from those of shallow parts. Aiming at the disaster problems such as impact dynamics instability in deep coal mining at 3654 working face of Tangshan mine, the triggering factors were analyzed to explore the impact instability prediction and monitoring technology suitable for the complex geological environment of deep mining, and impact instability prevention and control methods such as unloading blasting and coal seam water injection were adopted to provide reference for the management of deep coal rock dynamics disaster.
