Simulation Analysis Research of Coal Mine Location

For coal mine complex environment,many noise and random error,it makes a larger location error in coal mine,thus can not achieve the precise positions of staff.This paper presents a method of proofread time average improvement.In some extent,relieve noise interference and random error of measured value.Simulation by Matlab 7.0 software,Simulation results show that this method can relieve noise interference and random error of measured value,effectively improve the positioning accuracy.It has practical significance toward the coal mine location.
