Abstract:For a long time in Wushan Copper Mine, the common method has been used in the construction of the skyscraper. There are some shortcomings in the common method of patio excavation, such as high labor intensity, low operation efficiency and high safety risk. Therefore, the "deep hole one-time blasting technology" is proposed to carry out the patio excavation test successfully. The test proves that it is feasible to use deep hole one-time blasting technology to replace the common method in patio excavation, and it is also a safe, efficient and economical construction method.
