Study On Completed Equipment Of Thinner Seam High Efficient Fully Mechanized Mining Face

It's a big challenge for China's coal industry to realize the high efficiency mining of thinner seam, with fully mechanized coal mining equipments as the biggest technical difficulty in thinner seam's high production and high efficiency miningFirst of all, it reflects in the contradiction between the mining equipments'high-power and high-reliability required by high efficiency mining and the smaller equipment space due to the thinner seam, which could not be solved efficiently.So the paper makes the theoretically analysis and application research on the type-electing and set-completing of thinner seam's fully mechanized coal mining equipments, taking Yanzhou Mining Group's thinner seam high efficiency mining completed equipments and technique research project as support.Grounded on the research and analysis of the theory and method of completed equipment, focusing the characteristics of equipment selection system for thinner seam's fully mechanized face, the paper establishes a new system based on ANNES production capacity forecasting BP Artificial Neural Network (ANN) model and fully mechanized face main parameters of coal mining equipments neural network forecasting model. The facts show that the new method is rational, the estimated fully mechanized face output accords with the actual production and the developed equipment satisfies the demand of the high efficiency mining of fully mechanized face, solving the problem of China's high efficiency mining of thinner seam.The paper does the research on BP network algorithm, neural network generalization ability and reliability for repairable system, taking...
