Abstract : This work has covered most of the problems related to the quantity-distance determination (also denoted as Inhabited Building Distance) from blast waves originating from the tunnel exit. Also, investigations of required depth of rock-cover above an underground ammunition storage magazine have been performed. The most valuable result has been the verification of scale modeling techniques as a means of establishing Inhabited Building Distances. The test series clearly demonstrated the need to perform model tests when magazine concepts differ from previously tested magazine concepts. The tests also demonstrated the advantage of the expansion chamber as a means of reducing the Inhabited Building Distance. For a typical situation with an explosive quantity of 300,000 kg, the area within the Inhabited Building Distance increases by almost 130% when the expansion chamber is deleted.
