Minimum wages is a very sensitive issue, so there is no place for "normally same." It must be exactly the same as published in the government notification. A scanned copy of last year's Central Sphere Minimum Wages is attached, where you can find the differences between Delhi and Central Sphere Minimum Wages.
Establishments Included in Central Sphere Minimum Wages
In the Central Sphere minimum wages, the following establishments are included, especially for the employees working underground and 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, Quartz, Silica, Graphite, Feldspar, Laterite, Dolomite, Red Oxide, Wolfram, Iron Ore, Granite, Rock Phosphate, Hematite, Marble and Calcite, Uranium, Mica, Lignite, Gravel, Slate and Magnesite."
