我国现在的井下火药库,是采用苏联四十年代的陈旧模式,随着人们对井下空气冲击波形成机理及传播规律等不断认识,此种形式的火药库目前在苏联亦可能被逐渐淘汰。 本文结合关于井下火药库的调研,从井下空气冲击波传播规律来谈谈改革井下火药库的必要性。 一、火药爆炸时的空气冲击波 当药包在无限空气中爆炸时,在有限的空间内,迅速释放大量的能量。剧烈的化学反应导致了爆炸气体生成物压力和温度的上升,继而改变了空气中分子的密度。同时,爆炸气体“活塞”式地压缩毗邻空气,于是气体就产生了压缩飞跃。这种冲击压缩的结果便产生了空
The underground powder magazine in our country is based on the old model of the forties of the Soviet Union. With the constant understanding of the formation mechanism and propagation laws of underground air shock waves, such forms of powder magazines may be gradually eliminated in the Soviet Union. In this paper, the investigation of underground powder storage is carried out to discuss the necessity of reforming underground powder storage from the rule of underground air shock wave propagation. First, the air blast when the gunpowder explosion When the kits burst in the infinite air, in a limited space, the rapid release of large amounts of energy. A violent chemical reaction leads to an increase in the pressure and temperature of the explosive gas product, which in turn changes the density of the molecules in the air. At the same time, the explosive gas “piston” compression adjacent air, so the gas produced a compression leap. This shock compression results in an empty space
