excavation order is more helpful for ground pressure to break rock than downward excavation order. Key words: inducted fracturing; high stress hard-rock deposit; excavation case; roadheader excavation... and phosphate rock. Fig. 3 Displacement field of inducted fracturing roadway vs exposure time While excavation started, the surrounding rock was in the shearing state and the plastic zone increased along......

the stimulation period of validity are important stratagem for petroleum and natural gas exploitation. Fracturing and acidizing are the main methods for stimulation as well as one of representative examples of rheology theory application in engineering. Based on analysis of low permeability reservoir characteristics, the fracturing and acidizing stimulation principles and main controlling factors were......
