系统工程是理论性和技术性兼备的综合性学科,它是对系统进行组织和管理的科学方法,也是研究和解决复杂问题的有效手段。我们应用其理论和方法,论证朔里煤矿主井提升系统技术改造的必要性和迫切性,并进行优化设计,应用网络系统组织施工,使改造后的主井提升系统获得了较优的技术经济指标。 Systematic engineering is a comprehensive discipline with both theory and technology. It is a scientific method to organize and manage the system and an effective means to study and solve complicated problems. We apply the theory and method to demonstrate the necessity and urgency of technical renovation of the main shaft hoisting system in Shuoli Coal Mine and carry out optimization design and application of network system to organize construction so that the upgraded main shaft hoisting system obtains a superior technical economy index.
