Treating Tunnel Floor Heave With Relieving Explosion Underground

摘要

The floor heave often happens in soft-rock in mining. In this paper, the principles of mechanics to treat tunnel floor heave with relieving explosion are analyzed. Based on it, the experiment parameters are given, such as the least buried depth, the kind of explosion, the powder capacity, drill pattern and so on. The result detected by sound wave detector shows it is an efficient way to prevent and control the tunnel floor heave with relieving explosion under ground.
