一种地震勘探用数码电子雷管引火药的研究OA北大核心

A primer powder of digital electronic detonatorsuesd in seismic exploration was developed.It is made by optimizing the ratio and mixing of two types of agents and various additives through doping process.It can be quickly and reliably ignited under the weak energy stimulation of the ignition resistor,thereby causing another agent to react quickly and form a detonation,achieving a microsecond delay in the action time of the detonator.The results show that,by using doping technology,optimizing the mixing time and increasing the defoamers,the primer powder was prepared and assembled into detonators.After detonation,the action time of detonators meets the requirements of the maximum delay time not exceeding 250 μs and the range not exceeding 80 μs.
