Abstract

The present invention provides a water-jet-flow continuously-drilling directional drilling machine. It is formed from winding mechanism, continuous steel pipe, steel pipe driving mechanism, steel pipe coalignment mechanism, water-jet-flow drilling bit, inclinometer while drilling, direction control system, high-pressure water pump and oil pump.

Description

technical field [0001] The invention belongs to the field of mining drilling, and relates to a horizontal drilling-slotting device which adopts high-pressure water jet technology to continuously advance and control the direction of underground mine strata. Background technique [0002] In mining engineering, geotechnical engineering, construction engineering and other fields, it is often necessary to construct horizontal holes or directional deep holes to achieve special purposes. For example: it is used for the advanced gas drainage in the down-trough tunneling of the underground mining face, and the gas drainage of the working face is carried out along the trough; it is used for the prevention and control of coal seam rock burst and other geotechnical engineering construction horizontal drilling and pressure relief rock breaking. The drilling rig of the prior art adopts the drill rod to rotate, and the principle of driving the drill bit to cut and break the rock is made. ...
