For the study of earthwork blasting theory and engineering practice of leveling the field, basing on the third period blasting engineering of Hui-Cheng aluminum at industrial park in Qi-Jiang county. By timely monitoring the building (structure) near the blasting area, the results of the monitoring data show that the influence of the nearby structures is within the range of safety. By linear regression analysis of the monitored vibration data, in the range of safe value, the maximum charge quantity of the second calculation point and the third point is predicted to guide the actual construction.
