| Abstract: | Aimed at improving the safety performance of shaft support, the paper introduces the use of the theory of structural reliability to prove the safety performance of supporting design in working face according to the characteristics of randomness and fuzziness of surrounding rock and shaft support. The paper gives supporting ultimate equation of state and highlights the comparative analysis of safe coefficient. The analysis and instances indicate that the fail-safe analysis of mine supports is an advanced method. |
