【摘要】 爆破工程的电磁感应起爆系统,由于与现有的电爆及非电爆起爆系统相比有着显而易见的安全特征和操作方面的优点,在近年内得到较大发展。1984年北京矿冶研究总院着手研究一种以电磁感应原理为基础的大功率,可检测的起爆系统,该项工作已获成功。每次起爆可以引爆的电雷管总数达到420～940发,与英国皇家化学工业公司(ICI)诺贝尔炸药有限公司的Magnadet系统相比,新系统可采用12米甚至更长的电雷管脚线。另一个引人注目的进步是特地为该起爆系统发明了一套检测仪表,这样就使该系统象在常规的电力爆破中一样可以在起爆之前进行检测。这套仪表也可以取代常规电爆中的检测仪表。这篇文章描述这些进展以及新起爆系统及其检测仪表在现场使用的情况。更多还原

【Abstract】 The electro-magnetic induction initiating system for blasting engineering, because of its obvious safety features and operational advantages over existing electric and non-electric initiating systems, has been greatly developed in the recent years. In 1984, Beijing General Research Institute of Mining and Metallurgy undertook a research programme to develop a powerful, checkable initiating system based on the electro-magnetic induction principles: The work proved a success. The total number of electric detonators of the system that may be blasted in each round has been increased to 420—940, and 12 meters or even longer legwires of the detonators can be used as compared with the MAGNADET system developed by the Nobel’s Explosives Company Limited of ICI. Another attractive progress made is that a set of testing instruments has been especially invented for the system, which makes it checkable before firing just like in normal electric blasting. This set of instruments can also replace normal testing instruments for electric blasting. The paper describes these developments and field experience with the new initiating system and its testing instruments to date.更多还原
