Electronic detonator explosion work testing method

Abstract

The invention discloses an electronic detonator explosion work testing method. The method comprises the following steps that S1, an explosion module, a pressure testing device and a signal conversiondevice are connected in sequence; S2, two electronic detonators are arranged, so that an annular loop is formed among an explosion device, the first electronic detonator and the signal conversion device; S3, the mass of the explosive package to be exploded is measured; S4, an annular loop among the explosion device, the second electronic detonator, the to-be-exploded charge and the signal conversion device is formed; s5, the explosion device discharges and detonates the first electronic detonator, generated shock waves are transmitted to the signal conversion device through the receiving end,then the second electronic detonator inserted into the to-be-exploded explosive package is detonated, energy released by explosion of the electronic detonator causes explosion of the to-be-exploded explosive package, and then explosion shock waves generated by the first electronic detonator and the second electronic detonator are transmitted to the signal conversion device; S6, the P-t curves recorded for the first time and the second time are respectively recorded as P1 and P2; and S7, shock wave energy and bubble energy are calculated. The method is accurate in experimental result and simpleand convenient to operate.

Description

technical field [0001] The invention relates to the field of practical application of electronic detonators, in particular to a method for testing electronic detonator explosion work. Background technique [0002] Digital electronic detonator is a detonating device that uses an electronic chip control module to achieve precise delay. In recent years, due to the increasingly urgent demand for safety control of the use of civil explosives in my country, digital electronic detonators perfectly meet my country's urgent control requirements for civil explosives.

Problems solved by technology

However, this method has some disadvantages. First, the material, size and processing quality of the small lead pots have an essential influence on the experimental results. Small lead pots of different materials and sizes will have different volumes produced by the explosion of the detonator. Therefore, the tested There will be deviations in the working ability of the detonator, so the material and size of the small lead tank must be consistent during the experiment; secondly, the volume readings before and after the explosion of the small lead tank will cause errors and cause inaccurate experimental results; in addition, the temperature reading error will also affect the experiment. It will have an impact, because in the experimental procedure, it is necessary to put the thermometer in the lead hole for 10 minutes before reading the temperature value and correct the detonator’s working ability through the temperature correction coefficient; in addition, the different filling materials and lengths will also affect the experimental results. Influenced, even in the small lead tank experiment, the explosion of the detonator may produce flying pieces, leading to the failure of the experiment
