The ZSZC15 Mining Electromagnetic Wave MWD Device employs a wireless electromagnetic wave transmission method to relay borehole trajectory information. It does not require wired drill pipes, allowing directional drilling with conventional drill pipes. The probe is equipped with a high-precision triaxial accelerometer and a new magnetic sensor to ensure accurate and reliable measurement. It features a newly designed electromagnetic wave transmission sub with a multi-coaxial connection method, utilizing a limit design for effective and reliable connections. Its structure is robust, and installation and disassembly are simple, making it suitable for various working conditions.
