Abstract :
Based on the theory of fuzzy mathematics to describe working conditions of the system, which combined with experiments, to be a calculation method with membership function of normal distribution. It was closer to the actual conditions, so as to ensure system reliability. To introduce construction conditions and performance characteristics of electro-hydraulic feed System of Hydraulic Roof Bolter, and connected with experiment data of practical construction, the feasibility of research method was verified.
