Delay Detonator Of The Small Millisecond Acupuncture Research And Application

The impact of configuration, charge of design, test method of on delay characteristics of stab millisecond-delay detonator was been studied, also the output power of the mini detonator was studied. Through the tests, some useful conclusions are as follows:1) The more primary-explosive contents in stab compositions the lower time processed when stab compositions ignited.2) To B-Pb₃O₄-BaCrO₄ delay composition, the smaller particle size, the better delay precision.3) A attenuator which has a ignite channel in stab millisecond-delay detonator can improve delay precision.4) The fragment initiation in the limited charge interspaces can make long function distance and high output performance.
