| Abstract: | Based on the relation of wall rock pressure and hydraulic support holding power, the support and wall rock are regarded as one system. Through studying the support system of fully mechanized working face and its characters, the main factors that affect support system reliability are analyzed. The project system reliability analysis method is adopted. The limit state equation is established. The calculation method of fully mechanized working face support system reliability is pointed out. |
