Design and Implementation of Coal Mine Safety using IoT

2018-4-8  Traditional coal mine monitoring systems tend to be wired network systems, which play an important role in coal mine safe production. This system controls the ventilation demand to mine workers depending upon present climate conditions within the mine field. Here we proposes a design of a Wireless Sensor Network (WSN)

EVALUATION OF UNDERGROUND COAL PILLAR DESIGN

2011-5-15  Indian mines have about 60 % of the coal blocked in the form of pillars. This investigation critically reviews the different practices of pillar design followed around the world in general and evaluates the existing practices of an Indian mine in particular. Geotechnical factors of a nearby underground coal mine has been determined in the laboratory.

Longwall Mining Method and Design 911 Metallurgist

2018-5-30  Longwall mines produce more than 30 pct of all underground coal, up from 5 pct just 15 years ago. The continued growth of longwall mining without appropriate multiple-seam planning may increase the cost and risk of mining. Optimization of the mine design factors is arguably the primary means for controlling interactions between operations.
