为了安全、高效地处理废旧爆炸物品,以销毁广州市废旧炸弹为例,介绍了硐室爆炸法的销毁系统。硐室销毁炸弹系统由销毁硐室和平硐(L型)组成,距离销毁硐室门前2m处设一面挡墙。L型平硐是巷道结构,前部分约20m,断面约为1.5m×1.8m,然后向左垂直转弯,断面相同,长5m,爆破时可以有效地控制弹片和飞石的飞溅。挡墙能有效阻挡冲击波,减少危害。应用结果表明:与传统燃烧法以及裸露爆炸法相比,硐室销毁废旧爆炸物品具有警戒范围小、施工组织简单、销毁效率高、危害可控以及便于消除安全隐患等特点,是一种安全、有效的方法。 相似文献

为了安全有效、完全彻底销毁收集到的废旧炮弹,先对衢州市公安机关收集的废旧炮弹进行检测、鉴定,确定属于非生化类和非放射性炮弹后,根据待销毁废旧炮弹的性质和销毁工作要求,提出了坑内爆炸法销毁方案。按照销毁场地选择原则,选择了一处大型矿山中部的废弃石料堆填区,设置多坑安放待销毁废旧炮弹,采取毫秒延时导爆管雷管起爆技术,同时击发起爆的方式,共销毁迫击炮炮弹60枚,炮弹尾翼2枚,鱼雷463枚,手榴弹62枚,手雷16枚,穿甲弹2枚,航弹1枚。着重阐述了待销毁废旧炮弹的装卸搬运、安全警戒、爆后检查等各个工作环节,并对爆破振动、爆炸冲击波和弹片冲击的最小安全距离进行了安全校核。通过充分的准备、精心的设计和精细的施工组织,使得衢州市公安机关每一次销毁废旧炮弹工作安全、顺利完成,没有发生任何事故和产生次生灾害,为类似销毁工作提供参照。 相似文献

The Swedish Armed Forces have large stocks of ammunition that were produced at a time when decommissioning was not considered. This ammunition will eventually become obsolete and must be destroyed, preferably with minimal impact on the environment and in a safe way for personnel. The aim of this paper is to make a comparison of the environmental impacts in a life cycle perspective of three different methods of decommissioning/destruction of ammunition, and to identify the environmental advantages and disadvantages of each of these destruction methods: open detonation; static kiln incineration with air pollution control combined with metal recycling, and a combination of incineration with air pollution control, open burning, recovery of some energetic material and metal recycling. Data used are for the specific processes and from established LCA databases. Recycling the materials in the ammunition and minimising the spread of airborne pollutants during incineration were found to be the most important factors affecting the life cycle environmental performance of the compared destruction methods. Open detonation with or without metal recycling proved to be the overall worst alternative from a life cycle perspective. The results for the static kiln and combination treatment indicate that the kind of ammunition and location of the destruction plant might determine the choice of method, since the environmental impacts from these methods are of little difference in the case of this specific grenade. Different methods for destruction of ammunition have previously been discussed from a risk and safety perspective. This is however to our knowledge the first study looking specifically on environmentally aspect in a life cycle perspective. 相似文献
