露天矿半连续运输系统可靠性研究

The study of reliability of semicontinuous convey system in surface mine

在以往的露天矿半连续运输系统可靠性分析中 ,实质上一般进行的只是其中的一部分环节即连续部分的可靠性分析。运用排队理论 ,加上相应的假设 ,提出了对半连续运输系统中连续环节前间断部分可靠性分析的处理办法 ,另外提出在进行半连续系统可靠性分析时还应在间断和连续环节间加上储矿仓环节 ,这样才能真正体现整个半连续运输系统的可靠性分析。

In essence,analysing reliability of semicontinuous convey system in surface miners in the past is only to analyse reliability of continuous link as a past of the whole semicontinuous convey system.This paper apples Queuing Theory and add up authors own some standpoints to put forward a way to handle reliability problems of discontinuous part in front of continuous link in the whole semicontinuous convey ststem.In addition this paper put forward when calculating the reliability of the semicontinuous of the semicontinuous convey system in surface mines,the discontinuous subsystem and a coal bin subsystem should be added to the existed mathematical model.So new model can embody the feature of the whole semicontinuous convey system.
