Air bag restraint system gas generant based cracking barrel and near-people blasting method thereof

Abstract

The invention relates to an air bag restraint system gas generant based cracking barrel and a near-people blasting method thereof. The cracking barrel comprises a gas generant shell and a gas generant, wherein the gas generant needs certain pressure to trigger combustion; the gas generant comprises an oxidant, an acrylate cross-linking agent, a plasticizer, a vinyl trisilane lubricant, a combustion agent guanidine nitrate and a catalyst iron oxide; the gas generant shell has certain pressure therein, is further equipped with a resistance wire; the resistance wire is connected with a plug through a delayer outside the gas generant shell; and pins for connecting external circuits are further arranged on the plug. The cracking barrel cannot trigger and combust the safe environment-friendly type gas generant under atmospheric pressure, and is convenient and efficient to operate.

Description

technical field [0001] The invention relates to the field of blasting construction, in particular to a cracking cylinder based on a gas generating agent for an airbag and a blasting method thereof. Background technique [0002] In the current blasting construction, the use of explosive blasting is still the absolute mainstream production method. However, the explosive blasting method has unavoidable shortcomings, such as relatively high operational risk, relatively large safety hazards, easy to cause gun smoke poisoning, and relatively strict regulations on the use of explosives. With the continuous innovation of science and technology, non-explosive crushing methods have been continuously developed and applied in recent years. They mainly use mechanical, jet and gas expansion to do work, and cause rock crushing with a small tensile stress. [0003] Using machinery and high-pressure jets to crush rocks has the biggest disadvantages of low efficiency, high labor intensity, e...
