Product Overview
The Intelligent Directional While-Drilling Measurement System (collar-powered version) provides trajectory detection and monitoring for directional boreholes in underground coal mines. During drilling, trajectory data is read in real time and displayed in tables and curves, allowing engineers to keep the borehole on the designed path.
Product Description
Directional boreholes are essential for gas drainage, water exploration and advanced geological investigation in coal mines, and keeping each hole on its designed trajectory is critical for effectiveness and safety. The Intelligent Directional While-Drilling Measurement System delivers collar-powered measurement during the drilling process: sensors housed in the drill string measure the borehole attitude while drilling, and the system converts these measurements into clear trajectory information.
Trajectory data can be read in real time during drilling and displayed in both tabular and curve formats, giving the drill operator immediate feedback on hole direction at every stage. Reference trajectories can be loaded directly from design files, and the system calculates the bend adjustment angles needed to correct the drill path back to the planned line. This closes the loop between design, drilling and correction without waiting for post-drilling surveys.
Because the system is collar-powered, power and signal transmission are handled through the drill string itself, simplifying downhole hardware and reducing the battery constraints typical of self-contained instruments. The result is a practical while-drilling measurement tool that keeps boreholes accurate, improves gas drainage and exploration drilling productivity, and supports the growing use of directional drilling in underground coal mines.
