非电起爆系统在硐室爆破中的应用

APPLICATION OF NON-ELECTRIC PRIMING SYSTEM TO CHAMBER BLASTING

根据电雷管易被杂散电流引爆而导致硐室爆破早爆事故这一事实，阐述了在调室爆破中应用非电起爆系统的意义，与此同时，就起爆体的安装、装药结构、网络敷设、网络防水以及"X"形联通等问题发表了见解，对碉室爆破的安全实施具有一定的指导作用。

In view of the fact that electric detonator is so easily primed by stray current as to result in the occurence of early blasting accident in chamber blast, the author discussed the significance of nonelectric priming system in chamber blasting and put forward some new ideas on the issues of priming element installation, charge structure, network arrangement, water prevention for network and 'x' form connection etc, which would make a contribution to safe practice of chamber blasting.
