我矿从1980年4月起,就开始推广应用塑料管非电导爆系统起爆法。我们采用绵阳化工厂生产的导爆管和雷管塞加工非电瞬发雷管在马槽滩矿区进行浅孔挤压,前后共用导爆管2300米、崩落矿石达3万吨;与此同时,我们还采用华丰化工厂生产的非电毫秒雷管在岳家山矿区和马槽滩矿区进行中深孔毫秒挤压爆破,截至今年四月份,已进行了19次,崩落矿石达33.9万吨。均取得显著的效果,深受工人欢迎。目前,我矿中深孔挤压爆破已全面推广应用非电导爆系统起爆法,并在掘进作业中试验推广这项先进起爆技术。
My mine from April 1980 onwards, began to promote the use of plastic pipe non-conductive blasting system initiation method. We use the Mianyang chemical plant production of detonators and detonators plugs processing non-electric instantaneous detonator in the Matsudoutan area shallow hole extrusion, before and after the detonating tube 2,300 meters, the collapse of ore up to 30,000 tons; At the same time, we In addition, non-electric milli-seconds detonators produced by Huafeng Chemical Factory were used to carry out medium-deep-hole millisecond blasting in the Yuejiashan mining area and Mabatan mining area. Up to April this year, 19 explosions have been carried out, with 339,000 tons of ore falling. Have achieved remarkable results, welcomed by workers. At present, the deep-hole extrusion blasting in mine has been fully popularized and applied to the initiation of detonation method of non-electrical conductivity blasting system, and the piloting and promotion of this advanced detonation technology has been carried out in the tunneling operation.
