摘　　要：通过对四川松林河洪一水电站竖井施工的介绍,阐述了在岩石破碎、裂隙发育和竖井超长(大于LM200型反井钻机施工理论深度)等诸多不利条件下,利用LM200反井钻机在遇到诸多问题的情况,克服种种困难,最终顺利完成本工程竖井导井施工,为类似工程提供了一定的经验。Shaft construction of Hongyi hydropower station on Songlin river in Sichuan province is described.The shaft pilot construction is completed successfully by LM200 raise boring machine under difficult conditions,including fractured rock,crack development and super long shaft(longer than theoretical construction depth of LM200 raise boring machine).These experiences can be used for reference in the similar projects.
