Brown coal mining limits in North Bohemia in the case of Bílina had been under preparation for a long time with the cooperation and agreement of the surrounding communities. It would ensure work for a further generation of people from 2030 to 2055 and would guarantee heating for four million people dependent on lignite-fired central heating systems, he said. According to Environment Minister Brabec, it would have to be clear before any possible lifting of the limits that there was a need for the coal. "We have to be sure that we really need the coal, when we will need it and what we need it for.
Environmental impact of the coal industry This is due to the relaxation of pressure and fracturing of the strata during mining activity, which gives rise to safety concerns for the coal miners if not managed properly. The buildup of pressure in the strata can lead to explosions during (or after) the mining process if prevention methods, such as "methane draining", are not taken. In 2008 James E. Hansen and Pushker Kharecha published a peer-reviewed scientific study analyzing the effect of a coal phase-out on atmospheric CO levels. Their baseline mitigation scenario was a phaseout of global coal emissions by 2050. Under the "Business as Usual" scenario,
