Abstract: According to the available industrial standards, based on no related stipulation status from the evaluation on the positioning accuracy of the mine underg round personnel measures with the signal TOA technology, the evaluation method for the positioning accuracy of the mine underground personnel was provided based on the TOA technology. The time resolution evaluation conditions of the positioning system, the frequency evaluation conditions of the processor and the evaluation con ditions of the positioning error were applied to the evaluation on the static positioning accuracy. The limit conditions of the positioning patrol checking period and the lim it conditions of the maximum displacement speed were applied to the evaluation on the dynamic positioning accuracy. The combination with the evaluation results of the static and dynamic positioning accuracies was applied to evaluate the positioning accuracy of the mine underground personnel based on TOA technology. The design 0 n the positioning system of the mine underground personnel could be guided based on TOA technology. The paper provided that the method could be applied to the pos itioning accuracy evaluation of the mine underground personnel based on the TOA technology and the paper provided the guide cases of the positioning key equipment index design for the mine underground personnel.
