The invention discloses a mining trajectory measurement exploring pipe control system while drilling. The system comprises a power supply management module, a central control unit, a three-shaft acceleration sensor, a three-shaft magnetoresistive sensor, a three-shaft angular velocity sensor, a storer and a data communication interface module, wherein the power supply management module supplies power for all the modules; the central control unit is connected with the three-shaft acceleration sensor, the three-shaft magnetoresistive sensor, the three-shaft angular velocity sensor and the storer through an external bus; and the central control unit is connected with the data communication interface module. The system has the advantages of high integration degree, lightness, high measurement precision, good stability and excellent performance, takes the leading position in like products, and can determine the drilling trajectory through detecting the measurement point information in underground coal mine gas drainage drilling.
