Abstract
Description
technical field
[0001] The invention relates to a horizontal drilling orientation system of a deep hole drilling vehicle. Background technique
[0002] The horizontal drilling directional system of deep hole drilling rigs is widely used in coal mine deep hole drilling rigs. Due to the special environment of coal mines, satellite positioning and radio navigation cannot be used on deep-hole drilling rigs. At present, the most commonly used horizontal drilling orientation system for deep-hole drilling rigs uses self-service positioning systems. The inertial unit is often used in self-service positioning systems. The advantage of the inertial unit is that it is independent of external information, but the complex magnetic field environment under the mine, the drift error of the inertial unit, and the difficulty in calibration will make the self-service positioning system unreliable or even unavailable; another type of horizontal drilling orientation system It is a total station...
