双输送机综采放顶煤工作面可靠性

The Reliablitv of Two Convevors Fullv Mechanized Caving Work Face

建立了双输机综采放顶煤工作面平行作业工艺系统二状态和三状态可靠性致学模型,实例计算表明,按三状态考虑计算出的工作面有效度比较符合实际.

This paper sets up two-state and three-state reliability math model of two conveyors fully mechanized process.The calculation of actual example shows the calculation for work face availability on the base of three states conforms to practice.
