Dear Mr. Neer,
Minimum Wages is very sensitive issue so there is no place of "normally same. It must exactly be the same as published in Govt. notification. A scanned copy of the last year Central Sphere Minimum Wages is placed in the attached file wherein you can find the difference between Delhi & Central Sphere Minimum Wages.
In central sphere minimum wages the following establishments are also included specially for the the employees working in underground & above ground:-
"Gypsum, Barytes, Bauxite, Manganese, China Clay, Kyanite, Copper Clay, Magnesite, White Clay, Stone, Steatite (including the mines producing soap stones and talc), Ochre, Asbestos, Fire Clay, Chromite, Quartzite, Quartze, Silica, Graphite, Felsper, Laterite, Dolomite, Red Oxide, Wolfram, Iron Ore, Granite, Rock Phosphite, Hematite, Marble & Calcite, Uranium, Mica, Lignite, Gravel Slate & Magnesite"
The notification which you enclosed is missing the establishments of Coal Mines & Non-Coal Mines.
