It's been almost 70 years since the end of the worst military conflict of all times, the World War II, during which millions of people died. It is a sad fact that it still causes casualties even today. The problem lies in thousands of different pieces of munitions located throughout Europe. The biggest problem is posed by unexploded aerial bombs that have in recent years took its toll on bomb disposal experts as well as other people. The problem of aerial bombs are mainly American and British origin, which bear long-term mechanical - chemical igniter. The design of these igniters does not allow their simple unscrewing from the body itself, and even the handling of these aerial bombs may cause its explosion and the threat to all persons located in its vicinity. Even in our country can be found these air bombs with this type of igniter. This thesis deals with the possibilities of such a disposal with regard to economic and technological possibilities of the Czech Police bomb disposal experts. Therefore, research was conducted with a focus on how best to dispose of aerial bombs. Bomb disposal experts were approached to give their professional opinions. A part of the research was the study of foreign literature dealing with this issue. The sad fact is that this problem is not satisfactorily resolved anywhere in Europe. Abroad, various methods were used as appropriate, such as using high pressure water cutting or blasting the use of special keys. As demonstrated by accident in 2010 when in German Göttingen three bomb disposal experts died in liquidation of aerial bombs using high-pressure cutting, this method and similar have proven to be inappropriate. The preparation of these special methods takes an excessively long time, and in many cases the bomb requires manipulation. Bomb disposal experts of the Czech Republic along with other experts are developing and improving the explosive separation method using a special explosive (ammunition). The most appropriate seems the use of long flexible bomb explosive: RAZOR made by a Czech company - VÚPCH Pardubice - Semtín. The explosive is attached to the body of the bomb either on its perimeter or in the axis of the bomb and this leads to the separation of the lighter or pull out the body of the lighter without explosion of the body of the bomb. Practical experience shows that the use of this special method can reduce time to prepare bomb disposal and the handling of the bomb is minimal or none. Unfortunately, there is always a risk that there will be accidental explosion of aerial bombs and therefore is imperative to comply with all safety measures to the maximum extent possible. |
