Power supply control method and system for logging-while-drilling detection pipe in underground coal mine

The invention discloses a power supply control method and system for a logging-while-drilling detection pipe in an underground coal mine. The method comprises the following steps: monitoring the vibration of the logging-while-drilling detection pipe; if the monitored vibration is not greater than a preset vibration threshold value and the duration time t is less than T1, enabling a gamma detectionunit and an inclination detection unit of the logging-while-drilling detection pipe to keep the states of the previous moment; if the duration time t is not less than T1 and less than T2, executing aprocess A; if the duration time t is not less than T2 and less than T3, executing a process B; if the duration time t of the vibration state is not less than T3, executing a process C; if the monitored vibration is greater than the preset vibration threshold value and the duration time t is less than T1, enabling the gamma detection unit and the inclination detection unit of the logging-while-drilling detection pipe to ke
