[0002] To prevent the occurrence of floor heave in coal mines, it is necessary not only to strengthen the tunnel support and reinforce the two sides, but also to take measures to reduce the amount of floor heave to an allowable range according to the specific surrounding rock geological conditions. Usually, reinforcement method, pressure relief method, combined method and reinforcement of tunnel sides and corners are adopted to reduce the floor heave phenomenon. Among them, reinforcement method is to control the floor heave by increasing the strength of the floor surrounding rock or increasing the support force of the floor surrounding rock.
