| 摘 要： | 在紫阳瓦板岩矿山生产中,要求围岩和矿体同时爆破。根据现场的实际条件,围岩爆破选用加强松动硐室爆破,矿体爆破采用大空腔比不耦合条形装药松动爆破技术。本文介绍了爆破方案,包括药室布置、爆破参数选择、药量及装药结构、起爆网路等有关技术。本次爆破达到了预期爆破效果。

| Abstract: | Chamber blasting was selected for the exploitation of Ziyang wabanrock.In the exploitation rock was mined by strengthened loose chamber blasting,and the ore was mined by big cavity ratio non-coupling linear charge blasting.In this paper,the blasting design was introduced,including the layout of charged chambers,the selection of blasting parameters,charge weight,charging structure and priming network.The expected effectiveness was quite satisfactory. |
