摘　　要：依托沂蒙和深圳2个蓄能电站斜井(竖井)开挖案例,对"小直径机+人工扩挖"和"定向钻+大直径机"2种导井施工技术进行系统研究,从施工条件、进度、安全、质量、成本5个方面进行比较分析。结果表明,现阶段"小直径机+人工扩挖"虽具有成本优势,后期随着大型反井钻机价格水平回落,"定向钻+大直径机"未来仍将具有广阔的应用前景。Based on the cases of inclined shaft excavation in Yimeng and Shenzhen storage power station,the paper systematically studies the two kinds of guide well construction technologies of"small diameter machine+manual expansion"and"directional drilling+large diameter machine",and makes a comparative analysis from five aspects,such as construction conditions,schedule,safety,quality and cost.The results show that although"small diameter machine+manual expansion"has cost advantage at the present stage,"directional drilling machine+large diameter machine"will still have broad application prospect in the future with the price level of large counter-well drilling rig falling later.
