Limit Depth of Rock Mine Shafts for Underground Shelters

Abstract:

Today, especially after the several technical accidents, the last one in France Flamanville power station near Cherbour in January 2017 risks of the nuclear hazards due to technical, terrorist or military accidents continually rising. In this situation is of a great importance to start with a retrofit those of underground spaces that was decommissioned in last years and to start thinking about reuse of mining shafts as a fallout shelters for protection of civil population. And the first step is to start with selection of the identify spaces with a mathematical models for selection of the rocks massifs that can be useful for porpoise of the underground shelters. The need to utilise specific geological data, which project organisations usually do not have available. The physical-mathematical properties of rocks are not sufficiently portrayed in these methodologies, which complicates execution of calculations and reduces the credibility of these calculations. The methodology for calculating the stability of rocks around a mine works proposed in the article enables resolution of the task complexly for the conditions of individual deposits, utilising the generalised values of rock property indicators.
