Abstract:

Abstract: In open-pit mining, blasting parameters are formulated according to the whole mining lithology distribution. According to the design parameters to blast, after blasting, it will cause the phenomenon of high block rate and pulling low, which causes serious effect on the mining progress of mine. According to the phenomenon of large block pulling low in Nalinmiao disaster control engineer, the mine carries out blasting parameter optimization and innovation.

摘　要：在露天开采中，爆破参数是根据矿区整体岩性分布制定，如果安全按照设计参数起爆，爆破后往往会造成大块率较高、拉低等现象，这将对矿山的采掘进度造成严重影响，针对纳林庙灾害治理工程现存在的大块、拉底现象进行爆破参数优化与创新。
