The YSX20 measurement-while-drilling device for mine is mainly used for control while drilling in the construction process of near-horizontal directional drilling. It can measure the main parameters such as dip Angle, azimuth and tool face while drilling, and realize the real-time display of hole drilling parameters and track, so that the drilling personnel can know the drilling construction situation at any time, and adjust the direction of the elbow in time, so that the drilling can extend according to the designed track. The device is mainly applicable to the drilling construction of underground coal mine gas extraction drilling hole, water exploration hole, advance exploration hole, floor grouting reinforcement, and can also be applied to the ground exploration hole, coal bed gas mining horizontal branch Wells and other drilling construction.
1. The probe adopts the power supply mode through the hole to avoid battery replacement and the communication adopts the secondary amplification design to ensure the working stability of the measuring probe;
2. The probe adopts self-developed sensor, which is the first "true" fluxgate product in China to ensure high accuracy and reliability of measurement data;
3. The computer adopts built-in dual-channel communication to enhance practicability and avoid single-channel failure and shutdown;
4. Computer adopts high reliability short circuit protection circuit to avoid communication interruption or circuit damage caused by short circuit of measurement cable;
5. Communication circuit according to military grade requirements, is the industry's first non-polar design, two measuring terminals arbitrary switch, improve efficiency, easy to operate;
6. All connecting line joints are equipped with buffer spring protection, improve the stress state of the bending, improve the service life of the connecting line;
7. The computer adopts Android operating system, which is the first in the mining field in the world, providing a more stable operating platform for measurement software;
8. Survey software design, following the current advanced drilling process requirements and conditions of use, commonly used keyboard shortcut Settings make the survey software simple, practical and more user-friendly. The MWD software is self-developed based on the Android operating system. It has the characteristics of reasonable setting, simple operation and fast measurement speed.
