Control of the Adverse Effects of the Blasting of Land Site Forming Works of Zhuhai LNG Project

Through understanding the engineering and blasting circumstances around and comparing blasting method,the paper,on the basis of spot blasting test and vibration monitoring during construction,discusses the optimization of blasting parameter,reasonable arrangement of work place,controlling of the position and direction of minimum holdout line and weak condition in partial rock and the strict controlling of maximum charge amount per delay interval,through which the adverse effects such as individual flying rock and blast vibration etc.are effectively controlled and the requirements on project,quantity and cost etc.are met at the same time.
