为了提高2m以下薄矿体采矿生产能力与经济效益，长沙矿山研究院与河北峪耳崖金矿合作进行了薄矿脉深孔崩矿采矿方法的试验研究。试验中主要运用了采矿方法模糊教学优选、台阶爆破参数优化、盘区无须往连续回采、薄矿脉深孔凿岩崩矿、微之字形孔不耦合装药、限定排数微差爆破、
In order to improve the mining capacity and economic benefits of thin ore body below 2m, the Changsha Institute of Mines and the Yu’erya gold mine in Hebei Province conducted a pilot study on the mining of thin-veined deep-hole collapse. In the experiment, fuzzy teaching optimization of mining method, optimization of bench blasting parameters, continuous mining of the plate area, continuous mining with thin-hole deep-hole drilling, uncoupling of micro-zigzag holes,
