摘　　要：在复杂边界已被掌握且两侧已进行全尾胶充填的条件下,冬瓜山矿柱采场的爆破设计,既要紧密结合复杂边界确定合理的孔网参数、崩矿方式、起爆顺序和装药结构以获得良好的爆破效果,又要采取微差爆破、留矿爆破、控制爆破和强化生产等措施保护好两侧充填体,以保证矿柱回采的安全性、经济性和高效性[1]。The both sides of the pillar stope, which have complexity boundaries, are concreted fillingbody at Dongguashan mine. To ensure the security, economy and efficiency of the pillars mining, it is necessary to determine a reasonable blasting parameters, the way of collapsing, detonating sequence and the charging structure for the good fragmentation effects by blasting design, but also to apply millisecond blasting, controlled blasting, enhanced production and other measures to protect both sides of the filling - body .
