Research on broken rock mechanism of static state dose

The static state broken dose doesn't produce harmful effection, such as yawp, vibration and dust...etc., it is a special material which can calm safely broken rock or concrete. The inflation pressure that this kind of material released can still keep on after tiny crack occurrence, the width of crack extends with time. This paper studied static state broken dose break rock mechanism, crack development regulation, and then study to develop new geology structure disposing technique.
