峒室爆破也叫大爆破,永登、昆明、启新、太原等水泥厂采用这种爆破的經驗証明,可以大大加速剝离和采准的进度。茲将几个厂矿山的具体作法,綜合介紹如下。一、峒室爆破的条件峒室由准备巷道和药室两个部分組成(参看图1)。炸药集中装在药室中。药室布置型式,根据爆破目的和岩石的性质以及地形条件而定。在几个水泥厂的矿山,多采用T字型,也有用Γ字型的。采用这种爆破方法时,爆破区周圍最好应无重要建筑物,以免爆破时产生的地震波、冲击波、飞石等損害建筑物。地形条件对于爆破效果有很大影响。峒室
Chamber blasting is also called blasting. Yongming, Kunming, Qixin, Taiyuan and other cement plants have used this kind of blasting experience to prove that they can greatly accelerate the progress of stripping and acquisition. Here are the specific practices of several plant mines, which are summarized below. First, the conditions of chamber blasting The chamber is composed of two parts of preparation roadway and medicine room (see Figure 1). The explosives are concentrated in the medicine room. The layout of the chamber is determined by the purpose of the blasting and the nature of the rock and the terrain conditions. In several cement factory mines, T-shaped and T-shaped are used. When this method of blasting is used, there should be no important structures around the blasting area to avoid damaging the buildings due to seismic waves, shock waves, flying rocks, etc. generated during blasting. Terrain conditions have a great influence on blasting results. Bedroom
