    Elementy teorii niezawodności i bezpieczeństwa konstrukcji w projektowaniu budowli podziemnych
    (Wydawnictwa AGH, 2005) Duży, Stanisław
    The choice of support of underground structures is executed with the usage of a range of data describing with smaller or bigger approximation. This status leads to a situation in which most of the data may be treated as variable. The valuation of mining support safety is possible only with the usage of the construction safety and reliability theory in which we can see three basic ideas: reliability, safety and quality. The paper presents the results of excavation realizing quality and an analysis of reliability and safety of 178 excavations located in 17 regions of GZW mines has been executed and has shown that an applicated support, due to the changeability of input data differences, was characterized by changeable error possibility. A possibility of using risk function as a target function in the excavation construction optimization has been indicated. The expediency of using the reliability and safety theory in underground structure designing has been proven.
