液态CO2爆破筒封孔器性能方案设计
摘要
气体爆破在矿山爆破领域越来越受到重视。其污染小，爆破过程相对炸药爆破缓慢平和，爆破后产出大块的整矿石，而非炸药爆破产生冲击波和溅射碎石，相对安全。液态二氧化碳因其价格低廉、运输方便、污染小等优点受到了高度的关注，而因其独特的物理特性使得其在气体爆破领域得到了大量的应用。而若要应用气体爆破方式就相应的需要一个能可靠封堵住气体的装置，因此液态二氧化碳爆破筒封孔器也就应运而生。
本首先对二氧化碳相关物理性质进行了阐述，简要叙述了液态二氧化碳相变时的参数变化；其次对液态二氧化碳爆破筒封孔器的结构进行了设计，确定封孔器各关键部分的组成，例如，膨胀橡胶的材料，骨架部分的材质等；然后参照现场作业的实际情况，对封孔器的各部分尺寸进行了设计；最后对封孔器进行了性能分析，计算校核各部分的稳定性以及可靠性。为了实现封孔装置的创新性、实用性及高度互换性，在本中对应设计了三种方案。同时在的结尾对三种方案进行对比评估和总结，得到了三种各具特色的封孔器。

ABSTRACT
Gas blasting is gaining more and more attention in mine blasting. Its pollution is small, the blasting process relative to the explosive blasting slow and calm, after the production of large chunks of the whole ore, rather than explosive blasting shock waves and sputtering gravel, relatively safe. Liquid carbon dioxide has attracted a lot of attention because of its low price, convenient transportation, small pollution and other advantages, and its unique physical properties make it in the field of gas blasting has been a lot of applications. And if the application of gas blasting on the corresponding need for a reliable gas blocking device, so the liquid carbon dioxide blasting barrel sealing device also came into being.
In this paper, the physical properties of carbon dioxide are described first, and the parameters of liquid carbon dioxide phase change are briefly described. Secondly, the structure of liquid carbon dioxide blasting drum is designed to determine the composition of key parts of the sealing device. For example, The material of the expanded rubber, the material of the skeleton part and so on. Then, the size of each part of the sealing device is designed with reference to the actual situation of the field operation. Finally, the performance of the sealing device is analyzed, and the stability of each part is calculated. reliability. In order to realize the innovation, practicability and high interchangeability of the sealing device, three schemes are designed in this paper. At the same time, the three schemes are evaluated and summarized at the end of the paper.
Key words: gas blasting ；liquid carbon dioxide ；sealing device
