A Study On The New Measurement Of Detonator Output

Detonator is the crucial part of the cartridge booster train and is the necessary primer unit during the engineering blasting, so its output is one of the main properties of detonator. It is very important to the design of detonator and the control on the producing and testing of detonator that a measurement system is established which can test the detonator output economically, conveniently, exactly and quantitatively or relative quantitatively.m this paper, based on the analysis of the measurements on the detonator output at the domestic and foreign research filed, the new measurement system that can measure the detonator output dynamically is confirmed inosculating the several advanced technologies such as fluid driving, sensor and the data collecting and processing. This measurement system makes use of the Impulse (Im) to token the detonator output relative quantitatively. Several kinds of fire detonator and stab detonator are tested by this new measurement system, and the test results show that the system has characteristics of good stability, high sensitivity and veracity on the detonator output and can reflect the change of charge and configuration very well. The repeatable using of the sensor of the measurement system can reduce the test cost, and the canceling of the leading can lessen the harm comes from the hard metal to the environment and people. So the new measurement system in this paper that is designed reasonably can measure the detonator output economically, conveniently, exactly and relative quantitatively.
