The paper discusses different radio frequency communication techniques being employed for Indian underground mines. Experiments were condu...
متن کاملNoise variability in underground room and pillar coal mines.
Noise in an underground coal mine has dominant components generated mainly from 3 sources: (a) continuous mining machines, (b) roof bolters, and (c) cars/vehicles used to transport personnel and/or coal. Each of these 3 noise sources also has a number of well-defined sub-sources with their own noise characteristics. Sound level meters were used to collect noise data in the form of instantaneous...
