摘　　要：在设备"等劣化模型"的基础上,提出以平均无故障工作时间tM和平均修复时间tR作为综采设备的可靠性寿命指标,并对其劣化规律进行了分析。针对综采设备可靠性特点及其影响因素,构建了液压支架的可靠性寿命指标体系,并采用隶属度函数方法进行了可靠性寿命的计算,其计算结果与生产实际有较好的一致性。MTBF and MTTR as the reliability of life indicators of mining equipment were proposed based on ＂the degradation model＂ for equipement,the degradation law was also analyzed.In view of the reliability characteristics and impact factors of mining equipment,this paper builds the reliability life indicators for hydraulic support system,and calculated the reliability life by the membership function method.The calculated results were good agreament with the actual production.
