Explanation:

Ministry of Coal has launched Single Window Clearance Portal, a unified platform that facilitates grant of clearances and approvals required for starting a coal mine in India.

• Presently, about 19 major approval or clearances are required to be obtained before starting a coal mine in the country. Some of them include approval of Mining Plan and Mine Closure Plan, Grant of Mining Lease, Environment and Forest Clearances, Wild Life Clearance, Clearances related to Safety, Environment, Rehabilitation of project affected families, welfare of workers etc.Commercial mining allows the private sector to mine coal commercially without placing any end-use restrictions.
• Private sector participation was permitted until the early 1970s. The Indira Gandhi government announced the nationalization of the coal blocks in two phases between 1971 and 1973.
• Further, there had been end-use restrictions and the private sector was not allowed to trade into the market making it unattractive for the private sector.
• Government of India has done away with these restrictions and 19 successful bidders have been allotted mines under the country’s first commercial coal mining auction.

Hence only statement 1st is correct.
