摘要
本文应用系统可靠性理论,建立了单一煤层、煤层群走向长壁采煤法采区采运系统和倾斜长壁采煤法采运系统的可靠性数学模型,给出了系统可用度、故障频度及平均工作时间的计算公式。并通过实例计算,对上述采运系统进行了可靠性分析。
With the theory of the systematic reliability applied, the reliable mathematical models of the extraction and conveyance system of mining section with the method of longwall mining along the single coal seam and multiple coal seams strike and that with the method of dip longwall mining are set up, and the calculating formulas of the effectiveness, the failure frequency and the average working time of these systems are also given. Finally, the reliability of the extraction and conveyance system mentioned above is analysed by examples.
