    Abstract:

    Some practical problems are exposed when long drilling rigs with large volume structure are used in coal mines with narrow alleyways and complicated geological conditions; for instance, the match of the functional structure and construction technology need to be improved, the mating and controllability of related equipments is imperfect. According to these problems, a kind of small narrow type directional drilling rig is designed by addressing some key technical issues; the performance and reliability of this new narrow type directional drilling rigs have been verified by industrial experiments and long-term application.
