Large modern mechanical equipment has become an important factor in determining the productivity and security of a mine. Roadheaders have become the most common tools during digging a long tunnel. However, frequent fault that is imperceptible limit to maximize its performance. FTA based on triangular fuzzy number was applied to analyze the fault of the roadheader of Hongyang mine 3 of Shenyang Coal Trade Group, the probability distribution of the fault of a roadheader and coefficient of fuzzy probability important degree of basic events was got, then the more special precaution and repair could be applied. The above provided important reference for equipment supervisors of coal mine
