摘要(Abstract)：

国内外煤矿井下水平定向钻进技术 (HDD)的发展具有不同的技术路线 ,这涉及钻进设备和钻具、钻孔监测仪器的研发 ,钻孔轨迹控制理论的研究等。本文阐述了煤矿井下HDD技术在国内外的发展特点及我国在该领域未来几年的发展方向
The development of Horizontal Directional Drilling has different technical ways at home and abroad.It includs R&D of drilling rigs, drilling tools and inclination, theory of drilling hole path, all show different characteristics. This paper clarifies the differences of HDD in coal mines between our country and other developed countries, as well as development direction of HDD in our country in the coming years.
