摘要

由于目前煤矿井下移动通信系统缺乏电磁兼容设计依据

常常导致井下移动通信系统工作不稳定或不能正常通信.针对煤矿井下环境状况以及电磁环境的特殊性

从理论上分析了环境噪声系数

提出了通过测量电场强度来计算得到环境噪声系数的方法

并且分析了不同的电机车巷道环境噪声特点

得出关于噪声系数的模拟方程.分析结果表明:井下输电线路对井下噪声系数基本没有影响

井下空巷道与只有输电电缆巷道的噪声系数随频率变化基本一致.架线电机车巷道在机车运行时

对环境噪声系数影响很大

噪声系数起伏变化大.由于接触网对电磁干扰的传播作用

在电机车巷道内只要有电机车工作

电机车巷道内各处噪声系数的起伏都较大.

Abstract

Currently

for the lack of electromagnetic compatibility design in underground mobile communication system

the system often works unproperly and unstably.This paper theoretically analyzed the noise factor and characteristics of the electromagnetic environment of the coal mine

and proposed a new method obtaiting environmental noise factor by measuring the electric field intensity.A noise simulation equation of motor vehicle roadway was drawn by calculating the environmental noise in different environments through the proposed method.The conclusions are drawn as follows: The power line in the underground affects the noise coefficient scarcely

the noise coefficient of the empty underground tunnel and the cable tunnel change with the frequency consistently.The moving electric locomotive ecxert great impact on the environment noise and the noise figure varies sharply.For the electromagnetic interference is spread by catenary

the whole motor vehicle roadway suffers larger noise when motor vehicle works.
