An ongoing agitation at one of Jharkhand's largest mines run by Panem Coal Mines Limited has put a full-stop on all work at the site for the last 20 days. Uncertainty hangs over the project, with locals vowing not to let a single coal-laden truck leave the mines until the displaced families are rehabilitated. Panem is a joint venture company between the Punjab State Electricity Board and a Kolkata-based private company. Its mine in the state's remote Pakur district has about 562 million tonnes of coal reserves. The company has been allowed to do open-mining for 44 years.
