FIELD: measuring.
SUBSTANCE: invention relates to measurement methods and devices for automated control of parameters of drilling and blasting operations, including at open pits, faces and other mining facilities. Method for measuring detonation velocity of an explosive in a well involves using a coaxial cable connected to an electronic measuring device, by means of which in process of explosive substance detonation a sequence of time delays of signal propagation in cable is obtained, and by means of electronic computing device the speed of detonation of explosive substance is measured by calculation. When processing the obtained data by an electronic computing device, a polynomial approximation is used to obtain coefficients of a polynomial which is an approximating function for measuring the value of detonation velocity.
EFFECT: increasing the accuracy of the method for measuring the detonation speed of an explosive with an electronic computing device by reducing the influence of fluctuation and discrete errors on the measurement results.
