Central Mine

Central Mine Planning & Design Institute Limited (CMPDI) is a consultancy and engineering services company that was set up in 1974 and is a subsidiary of Coal India Limited. From its base in Ranchi, Jharkhand, it offers technical and advisory services across the full lifecycle of coal and mineral projects, spanning geological exploration and resource evaluation, mine planning and design, environmental planning and monitoring, and geomatics, remote sensing and survey work. The company also provides infrastructure engineering, specialised technology services and management systems, chiefly for the coal industry and related mineral sectors. The institute operates as a Mini-ratna public sector enterprise and describes itself as one of the largest coal and mineral consultancies in India, reporting a market share of about 61 percent for the financial year 2025. As of the end of December 2025 it ran seven regional institutes located across the principal coal-producing states, including Madhya Pradesh, Chhattisgarh, Odisha and West Bengal, supported by eight equipped laboratories spread over the coalfields. It maintains one of the country's larger exploratory drilling fleets, which underpins its exploration and resource-evaluation work. CMPDI is the consultant of choice for Coal India Limited, and a large majority of its revenue is tied to work for the Coal India group. This close relationship with its parent and with the Ministry of Coal gives the company a steady project pipeline, while also leaving it exposed to the pace of activity in the coal sector and to policy and regulatory decisions that govern mining and environmental clearances.

The company allotted 2,73,10,500 shares to anchor investors at Rs 172 per share, raising about Rs 469.74 crore ahead of the issue. Notable participants included the Life Insurance Corporation of India and Nippon India Mutual Fund, each taking roughly Rs 105 crore worth of shares, and ICICI Prudential Mutual Fund with about Rs 55 crore. Other anchors included LIC Mutual Fund, Baring Private Equity India, BNP Paribas, Edelweiss, Societe Generale, Goldman Sachs, General Insurance Corporation of India and Citigroup Global.
