報告表示，大型現(xiàn)代化煤礦已成為全國煤炭生產(chǎn)主體，煤炭產(chǎn)業(yè)結(jié)構(gòu)調(diào)整取得新進(jìn)展。
2019年，內(nèi)蒙古、山西、陜西、新疆、貴州、山東、安徽、河南等8個省(區(qū))原煤產(chǎn)量占到了全國的89.1%，同比提高1.2個百分點，煤炭開發(fā)布局持續(xù)優(yōu)化。
煤炭供給側(cè)結(jié)構(gòu)性改革取得顯著成效。截至2019年底，累計退出煤炭落后產(chǎn)能9億噸/年以上，安置職工100萬人左右。
同時，煤炭上下游產(chǎn)業(yè)一體化發(fā)展成效明顯，新能源、新材料、科技環(huán)保、現(xiàn)代金融等產(chǎn)業(yè)快速發(fā)展，推動了行業(yè)發(fā)展動能加快轉(zhuǎn)換，推動行業(yè)效益持續(xù)好轉(zhuǎn)。2019年，全國規(guī)模以上煤炭企業(yè)實現(xiàn)利潤2830.3億元。
