废弃矿井抽水蓄能电站基础建设装备关键问题及对策

Key problems and countermeasures for infrastructure equipment of abandoned mine pumped storage power station

为了充分利用煤矿废弃矿井遗留的大量资源及地下空间,促进能源枯竭城市更好地转型与发展,引入煤矿废弃矿井抽水蓄能电站新技术。分析了电站建设的总体改造方案,指出了电站建立的必要性、可行性和战略意义;结合现有的工程机械装备,从掘扩支护、土方作业、辅助机械、智能机器人等4个方面论述了电站基础建设装备群的构成及其应用场景;针对电站的具体施工与运维过程,总结了电站在输水系统的稳定支护与密闭、多巷道间的节流与引流、地下厂房的防渗与加固、厂房周围天然地下水的抽排、人员及大型设备的高效与安全运输等技术难题,并给出了相应的解决方案。

In order to make better use of the large amount of resources and underground space left by abandoned coal mines and promote the transformation&development of energy-exhausted cities,a new technology for abandoned coal mine pumped storage power station is introduced.The overall reconstruction plan of power station construction is preliminarily analyzed.The necessity,feasibility and strategic significance of the construction of power station are pointed out.Combined with the existing construction machinery and equipment,the composition and application of power station infrastructure equipment group are discussed in terms of excavation and expansion support,earthwork,auxiliary machinery and intelligent robot.Then,in view of construction,operation and maintenance of the power station,the technical problems are summarized,such as stable support and sealing of water transmission system,throttling and drainage between multiple tunnels,anti-seepage and reinforcement of underground powerhouse,pumping and draining of natural groundwater around powerhouse,and efficient and safe transportation of personnel and large equipment.Finally,corresponding solutions are proposed for construction of underground pumped storage power station and special equipment.
