| Summary: | The client of this thesis is Sandvik Construction. Sandvik is a member of ITA (Internation Tunnelling and Underground Space Association) and wanted to study current practises in vibration control when using drill and blast method. Parts of this thesis may be used in a further global study which Sandvik and ITA is considering to start about the same subject. The data was collected from lit-erature and standard collection of each country. The main purpose of this thesis was to collect vibration standards of Iceland, Norway, Sweden and Finland. Other parts of the thesis are current practises and general findings about the drill and blast method. In the last chapter a few challenging tunnelling projects with good vibration control practises are pre-sented. The outcome of this thesis was to translate the standard of each country to Eng-lish and to compare them with an example cases. In other chapters, the stages and general findings drill and blast method are presented.
