矿井感应信道研究报告

本文从“可连续移动性”角度,恰当地肯定了感应通信在目前我国矿井通信中应有的地位。并依据对多种信道在不同环境条件下的频率衰减特性进行实测的数据分析,提出了在井筒、巷道和采面较适宜的频段。并进一步提出了在选择信通时应注意的问题。对矿井感应通信机的生产和使用有一定参考价值。

A RESEARCH REPORT OF MINE INDUCTIVE PASSAGE

This paper was written from“continuous movability”point of view to affirm property the position of indactive passage in our present mine communication.Data anatyses are token form many lests according to attenuation characteristic of frequency with var ious passages under different evironmental conditions.Better frequen cies are put forward for shaft,tunnci and coal face.and at tention should be paid to the selection of induction passage.are indicated.This paper has a certain value for reference in the produetion and use of the machines of mine inductive passage.
