Vibration-based stress measurement-while-drilling device and measurement method

The invention provides a stress measurement-while-drilling device and method based on vibration, and relates to the technical field of mining engineering and drilling parameter measurement. The device comprises a drilling machine and a measuring drill rod, a plurality of axial acceleration sensors, a plurality of radial acceleration sensors, a plurality of lateral acceleration sensors, a data collector, a power supply and a signal transmitting device are arranged on the measuring drill rod, glue is injected into a cavity of the measuring drill rod, and a computer receives monitoring signals transmitted by the signal transmitting device. The various acceleration sensors transmit acceleration signals generated by measuring axial, radial and lateral vibration of the drill rod to the collector, the computer processes and calculates vibration displacement signals according to signal data packets, drilling machine parameters are calculated through the vibration signals, coal stress is inversely calculated, drilling
