Experiment Study of Blasting Excavation of Weathering Rock Slope

The quality requirement of weathering rock slope excavation by blasting is higher.The optimal construction method and blasting parameters were determined according to the slope rock conditions.The blasting experiment was carried out to verify the rationality of the blasting parameters,and evaluated the experiment result with the digital bore panoramic camera system,which used to test the blasting result.The test results show that the blasting scheme can meet the slope stability control requirements,and less damage on rock mass,which give some help to improve the blasting results and improve the efficiency of construction.
