Appreciation of Communication Problems in Indian Mines

Abstract

Recently some surveys have been conducted to appreciate and work out the requirements of communication equipment and systems for Indian mines.

Generally the requirements for Indian mines can be divided into three broad categories viz., (i) General Communication, (ii) Transfer of data, (iii) Communication with trapped miners. Implications of these requirements is broadly discussed and results of some experiments carried out in a few mines are presented.
