放矿漏斗和溜井被大块矿岩堵塞多出现于漏斗颈的6米高度,堵塞高度高于10米时,称之“吊漏”或“悬井”。以往靠爆破工人钻漏钻井处理悬碴,极不安全。我矿为了解决这一技术关键,与东北机器制造厂共同研制了矿山爆破弹,使爆破工人可以在漏门外点燃导火索,弹体靠发射药能量抛出,击中目标瞬时,引信作用使全弹爆炸,能安全迅速排除漏斗、溜井的堵塞,以保证矿山连续出矿。矿山爆破弹有安全可靠、操作简便、使用方便等特 Ore funnels and slippery well block by a large block of ore rock appear in the funnel neck 6 meters height, blockage height is higher than 10 meters, the “hangover” or “hanging well.” In the past by blasting workers drilling leakage hanging ballast handling, very unsafe. Mine in order to solve this key technology, and Northeast Machine Factory jointly developed a mine blasting bombs, blasting workers can ignite the fuse outside the door ignited, the projectile thrown by the propellant energy, hit the target instantaneous, fuze role Make the whole bomb explode, safe and rapid elimination of funnel, chute blocking, to ensure a continuous mining mine. Mine blasting shells are safe and reliable, easy to operate, easy to use and other special
