Dimensional Amalysis of Charge Formula Under Multi-boundary Conditions

Through inference of dimensional analysis and theory obtain the general form of concentrate charge formule in the multi-boundary blasting system. Simultaneousl y after many large-scale emgineering blasting tests are gone the cofficient in the middle for formula been determind. Therefore this paper establishs charge formula of engineering blasting under multiboundary conditions and moreover, incorporting the main charge formula from China and obroad in blasting engineering, now.
