Finanzierung innovativer Unternehmen,ngineering is quite different to that in most other branches of engineering. Factors that contribute to this situation in general practice and, more specifically, in an underground environment are presented. The state of the art is reviewed and supported by an appendix that provides a brief history

This forms the basis for designing mine workings in manners that not only avoid exposure to excessively high stress concentrations but also provide opportunities to exploit stress relief methods on both a local and regional scale..Issues examined in this chapter include chain pillar design
