The paper introduces two mathematical models about LOS(Line Of Sight) environment and NLOS(Non Line Of Sight) environment of Underground Staff TOA(Time Of Arrival) positioning. The basic station can receive the pulse response level of the polarized wave sent by man-carried alarm, so a will distinguish the signals of both LOS and NLOS. After TOA measured value in the NLOS environment minus its error, then the solution can be obtained by transferring the mathematical model of TOA position in NLOS environment to the mathematical model of TOA position in LOS environment. This positioning algorithm structure is simple, and the calculation amount is not large. After the analysis of practical test, the result can match the algorithm value and also meet the demand of positioning accuracy.
