1. Western Coalfields Limited
Workshop on
“The Technology Development &
Mechanisation of Mines
for enhancing
Coal Production & Productivity ”
20th January, 2015
Presentation by
Western Coalfields Limited

2. Western Coalfields Limited
WCL operates 80 Mines (41 UG, 39 OC) in 10 Areas (7 in Maharashtra & 3 in Madhya Pradesh)
WCL contributes more than 7% of the total National Coal Production from its 3.26% of the total National Geological Coal Reserves 2

Deep seated Reserve
High stripping ratio
Presence of Black Cotton Soil & Silt
Lower grade Coal
Smaller Capacity Opencast Projects
Very old and extensive UG Mines
Heavy Water seepage (Kamptee Series)
