Principle of Kilometer Directional Drill Drilling Technology
The application of kilometer drilling rig in the field of gas prevention and development is multifaceted, such as regional gas pre-drainage, tunneling pre-drainage, drainage of goaf gas, non-mining layer gas pre-drainage, not only can greatly reduce the investment cost of gas prevention and development, but also improve the drainage concentration, to provide quality assurance for the use of gas.
Drilling principle: A drilling method that uses a guiding system to extend the near-horizontal drilling trajectory to a predetermined target according to the design requirements, that is, the drilling axis is purposefully changed from curved to straight or from straight to curved. At the same time, the hole bottom guide device monitors the drilling parameters in real time, and then determines the oblique direction of the hole bottom screw motor.
