【Abstract】 On the basis of analysis of the reliability of coal bin, the model on the reliability of extraction and conveyance system is established in the high output and high efficiency mines which have one face or two faces, and the calculating formulas of effectiveness and relative rate of utility of the system are also given. The model can forecast the reliability indexes of the extraction and conveyance system, seek its bottleneck and present the measures for improving its reliability in order to provide scientific bases for enhancing the output and efficiency of mines. The model was applied in the extraction and conveyance system of Changcun Mine of Luan Coal Mining Bureau and proved that it was reliable and practical, and the calculated and analytical results of the system have guiding significance for this mine to realize high output and high efficiency.更多还原
