In view of the contradiction between the power supply time of the logging probe in hole of the gamma logging while drilling system in coal mine and the construction period of drilling operation, the energy-saving and power-saving control method and system based on the condition monitoring of the probe in hole are studied and designed, and the implementation process of the control method of the energy-saving and power-saving control system is introduced. The energy-saving and power-saving control method and system can make up for the shortcomings of several power supply modes of the existing coal mine downhole MWD system, or combined with the existing power supply mode, so as to solve the problem that the existing instruments can not meet all working conditions and process conditions due to the power supply problem.
