爆破震害控制
controlling seismic effect from blasting
baoPo zhenha一kongzhi爆破震害控制(eontrolling Seismic effeetfrom blasting)降低爆破地震强度，将震害限定在一定程度的技术。控制爆破地震危害，是爆破安全的必要手段。降震方法主要有三种。(l)微差爆破，其爆破地震波频率高、衰减快，可以实现ms级多段微差爆破，显著减少同时起爆的药量，以降低震动。(2)利用波的干涉作用，适当选择起爆时间间隔，在指定区域可实现波的干扰降震。(3)利用波通过不同介质时产生反射、折射和损耗，设置屏障降震。降震措施有预裂、光面、缓冲、孔内微差和斜线式多段顺序微差爆破等类型，合理应用将有最佳降震效果和较好经济效益。其要点:(1)尽量采用ms雷管新系列产品，新的系列有25一30段;延时精度显著提高;时间间隔趋于合理，便于爆破设计人员选择、调节间隔时间和控制每段药量，实现多段微差爆破。(2)临近边坡永久境界线的爆破，根据边坡岩体稳定性选用合适的降震措施，岩体整体性好的采用预裂爆破，岩体破碎、裂隙发育的采用光面或缓冲爆破。爆区宽度以不超过3Om为好。矿山边坡危险滑体下的爆破须限制一次爆破规模:炮孔不宜超过四排，爆区长度不宜超过滑体宽度的合一号。(3)在重要建筑物附近和危险边坡下方爆破时，尚需进行震动监测。 (韩子荣)
