The Problem of Country Rock in Underground Explosives Magazines (Zum Problem der Felsumlagerung bei unterirdischen Explosivstofflagern).

摘要

This report attempts to present a survey of the problem of country rock in underground explosives magazines. It deals first with the importance of this problem within the framework of the safety of such installations as a whole. This is followed by a qualitative presentation of the various factors that influence the problem of country rock. Finally, some of the formulations in use today are discussed and compared. This report does not, however, exhaust the subject, and the same is true of the conclusions derived therefrom. The specific purpose of this report is to serve as a point of departure for future investigations of this problem. The report was compiled after the Thun meeting of 9/10 December 1976, of the working group of German, Swedish, Norwegian, and Swiss experts, the group formed to carry out so-called 'Operation Block,' and which since then has been engaged in a regular exchange of experience in the field of explosives storage.
