The traditional method treats gyro-side as strong side in underground control network which has proved to be not sustainable.When gyro-sides are added,condition equations are needed and the approximate coordinates of Gyrosides are recalculated with the increased condition equation.However,it is not rational for the traditional method considering the gyroscope orientation sides as the steady line.Also the accuracy of the underground network adjustmentresult is influenced by the accuracy of gyro-sides.According to the analysis of long-term data collection and processing,a weighting model of Gyro-sides adjustment is proposed.It is more theoretical because of the integrity of the whole control network.Meanwhile,the swing of control network caused by the precision of Gyro-sides is avoided by the newmodel.Multiple of experiments show that the new weighting model can get higher positioning precision and reliability.It provides strong theoretical basis for the routine production and mine rescue.
