自五十年代以来,峒室大爆破在我国广泛地用于水利水电筑坝,矿山构筑尾矿坝,露天矿的基建剥离、铁路公路的开挖以及农田基本建设等工程中。这种爆破方法目前在上述各部门的某些工程中仍将继续使用。峒室大爆破通常一次爆破的药包个数比较多,装药量一般都在几十到几千吨,甚至上万吨。由于装药量比较多,爆破规模比较大,爆破地震效应的破坏作用比较显著,影响范围也比较广。如果在爆前对振动强度认识不足,估计
Since the 1950s, the large blasting room has been widely used in China for water conservancy and hydropower dam construction, construction of tailings dams in mines, stripping of open-pit mines, excavation of railway roads and farmland infrastructures. This method of blasting is currently still in use in some of the above-mentioned projects.峒 room blasting usually a burst of more than the number of kits, the charge is generally tens to thousands of tons, or even tens of thousands of tons. Due to the large amount of charge and the relatively large scale of blasting, the destructive effect of blasting seismic effect is quite obvious, and the influence range is relatively wide. If the understanding of the vibration intensity before the explosion is not enough, it is estimated
