采煤工艺的效益在很大程度上取决于回采和掘进工作面的工作可靠性。工艺系统可靠性的定量和定性评价,在矿山企业设计研究阶段就已经考虑了,这就可避免今后设计中可能出现的重大差错,这些差错可能会妨碍企业达到设计能力和其他一些技术经济指标的实现。解决这些复杂任务,在设计阶段是可能的。一系列大型煤矿的设计中,关于 The benefits of the coal mining process depend to a large extent on the reliability of the work performed on the mining and driving surfaces. Quantitative and qualitative evaluation of process system reliability has been taken into account during the design and research phase of a mining enterprise, which avoids any significant errors that may arise in future designs that may prevent the firm from achieving design capabilities and other technical and economic indicators achieve. Solving these complex tasks is possible during the design phase. A series of large-scale coal mine design, about
