硐室大爆破中条形药室的布置通常要求抵抗线基本均匀 ,偏差量一般不超过10 % ,否则不仅难以保证爆破质量 ,而且极有可能造成冲炮 ,引发不可估量的财产损失和人员伤亡。因此在开挖过程中对条形药室的各部分尺寸都严格加以控制。然而由于具体施工条件和施工水平所限 ,有时会出现?
The layout of bar-shaped chamber in chamber blasting usually requires that the line of resistance is basically uniform with a deviation of not more than 10%, otherwise it is not only difficult to guarantee the quality of blasting but also the possibility of causing it to result in an immense loss of property and personal injury . Therefore, the excavation process of the bar of the size of the various parts of the chamber to be strictly controlled. However, due to the specific construction conditions and construction of the limited, sometimes appear?
