Today there are eighteen members in the EFEE organisation, representatives of different European national societies engaged in the disciplines of Explosives Engineering. Within the European Union theEFEEstands for: • An organisation of professional users of explosives for industrial applications, and the experts on National and European level in its field; • The democratic right to representation and involvement in the policy-making, legislation and regulating processes in its field, on a National and a European level. There has been a great interest for this EFEE 2nd World Conference on Explosives and Blasting and the papers presented have provided the conference participants with new findings and experiences within the area of Health, Safety and Environment. New technical information of recent advances in the field of explosives application, research and technology was released and the conference also focused on the ongoing work inside EU with regards to harmonisation. Participants at this conference represented explosives users, manufacturers of explosives and equipment for drilling operations, researchers and professionals involved in construction, demolition, quarrying and mining industry. The many conference participants and exhibitors reflect that the conference has fulfilled its mandate admirably and the success with this conference will ensure that the 3rd EFEE conference will be held within two years in UK. Roger Holmberg Chairman, EFEE Technical Committee Gyttorp, July 2003 XI Copyright © 2003 Swets & Zeitlinger B.V., Lisse, The Netherlands 09056-Prelims.qxd 7/22/03 4:36 PM Page XIII Explosives and Blasting Technique, Holmberg (ed.) ©2003 Swets & Zeitlinger, Lisse, ISBN 90 5809 605 X Foreword of the President After the first successful World Conference held in Munich in 2000, the European Blasting Association would like to welcome the participants from all around the world to this year’s 2nd World Conference for Explosives and Blasting in the Czech capital of Prague. EFEE symbolizes technical progress and international co-operation regarding the harmonisation of stan- dards of blasting-techniques, pyrotechnics and other related technologies. Misapplications as well as disastrous aftermaths shall be prevented by exchanging experiences about the safe handling of explosives. Such exchange of experience not only takes place in the field but also on a more scientific level. EFEE was founded by five European countries such as U.K., Netherlands, Germany, Switzerland and Finland in 1988. It currently consists of 18 member states of which one is our host country the Czech Republic that joined as the first eastern partner soon after the political turn of events. The Czech Republic has not only been awarded the conference because of its well worth seeing scenery but also because it is a modern and ambitious country. The gorgeous city of Prague on the river Vltava has a long history and has been a centre in aspects of culture, trade and science for more than a millennium. Prague has a deeply moved history in which it had to bear misery but also saw incredible splendour. It is also this year that the new Czech Republic will be celebrating its 10th anniversary; one more reason to host this our 2nd conference in co-operation with the Czech Blasting Association. The European Federation of Explosives Emgineers welcomes all cronies and newcomers, so they may have the opportunity to contribute to the conference with their very own knowledge and experiences. You will have the chance to update yourself by attending some of the more than 175 different lectures or by visiting the 30 exhibitors on display. It is understood that also our versatile social programme will be of your interest. We welcome you again and wish you a pleasant stay in Prague.
