摘要
本文讨论了露天煤矿连续工艺系统可靠性的计算方法。据此可更正确地估计出系统的年有效工作小时数,从而为轮斗铲系统中设备规格的选取提供依据。针对元宝山露天煤矿连续工艺系统所作计算表明,对该矿选择的轮斗铲规格提出了改进建议。
The paper discusses methods for calculating reliability of a continuous miningsystem in a surface coal mine in order to estimate accurately its annual effectiveworking hours,which providcs a basis for selecting equipment of a bucket wheelexcavator system.The calculation for a continuous mining system in Yuanbaoshansurface coal mine indicates that the bucket-wheel excavators selected can not satisfythe designed annual output,and suggestions for improvement are made.
