Abstract:

Because of the contradiction between the rate of progress of the roadway excavation and the drainage in muduchaideng，the method of 1000-directional drilling machine applied in the drainage is put forward in this paper. The design and the construction are introduced. According to the characteristic of the 1000-directional drilling machine applied in the drainage, there are high efficiency and lower cost advantage and so on. It makes a technology breakthrough in the high voltage drainage. The technology has a certain reference.

Key words: 1000-directional drilling machine, the drainage, the roadway excavation, the high aquifer.
