REGRESSION ANALYSIS OF BLASTING VIBRATIONAL VELOCITY BY THE DOUBLE RANDOM VARIABLE METHOD

This paper introduces the double random variable method to improve the regression analysis of the blasting vibrational velocity and the application programs in computing of the method. Moreover ,with the data gained from the practical engineering projects, a comparision is made between the double regression analysis and the traditional single regression analysis applied in the blasting vibrational velocity. Computation proves that the program is convinient in operation and accurate in forecasting the blasting vibrational velocity and defining the safe explosive charge quantity and the safe distance.By the method an experimental formula most close to practice can be selected.It can achieve better results and is liked by the production department.
