摘要:
云南玉溪大红山铜矿现有采矿方法为分段空场嗣后充填法,采用大爆破工艺,由于一次爆破的药量过大导致对保留岩体的损伤较大,影响采场的稳定性。为解决此问题,按照多打孔少装药的原则,在距保留岩体一定距离处布置一排较为密集的炮孔,并减小单孔装药量,在主爆区起爆之前先起爆该排炮孔,形成一条具有一定宽度的缝隙,以减弱对保留岩体的损伤。基于变分模态分解和希尔伯特黄变换(VMD-HHT)方法对现场实测的爆破振动信号进行分析。结果表明:本次预裂爆破振动信号的瞬时能量分布区间主要集中在0~0.5 s内,频率分布的区间主要集中在40 Hz以内;采用3个测点的合速度进行减振率计算,得到3个测点减振率分别为21.0%、30.1%和38.5%,有效减小了爆破振动对保留岩体的损伤和破坏。
