| 近年来，随着我国对环境保护和安全生产的要求越来越严格，许多不具备生产条件的矿山被依法关闭，由于矿山开采遭到破坏的环境必然要进行生态修复，把美好的生态环境归还当地人民群众。在废旧(弃)矿山生态修复施工中，污染水的治理是关键工程之一，净化后的水一般需要通过排水管道进行自然排泄。在地势低洼处进行生态修复施工后，为了不形成内涝灾害，使用水平定向钻工艺实施一条排水管道，把水引到附近河流。本文以贵州省习水县良村镇劳荣煤矿生态修复工程为例，使用水平定向钻工艺成功实施一条长约580m的重力流排水管道，主要介绍了水平定向钻工艺在生态修复工程排水管道施工中的有效应用，其中现场采取的相关技术措施为国内其他地区实施水平定向钻工程提供了宝贵的经验。 |

| In recent years，as China’s requirements for environmental protection and safety in production have become increasingly strict，many mines that do not have production conditions have been closed according to the law. Due to the destruction of the environment caused by mining，it is necessary to carry out ecological restoration and return the beautiful ecological environment to the local people. In the ecological restoration construction of waste mines，the treatment of contaminated water is one of the key projects，and the purified water generally needs to be naturally discharged through drainage pipes. After ecological restoration construction in low-lying areas，in order to avoid waterlogging disasters，a horizontal directional drilling process is usually used to lay a drainage pipeline to divert water to nearby rivers. Taking the ecological restoration project of Laorong coal mine in Liangcun Town，Xishui County，Guizhou Province as an example，it mainly introduces the effective application of horizontal directional drilling technology in the construction of drainage pipelines in the ecological restoration project. Successful implementation of a 580m long gravity flow drainage pipeline with horizontal Directional drilling technology，The relevant technical measures taken on site provide valuable experience for the implementation of horizontal directional drilling in other regions of China. |
