能源信息署表示，煤炭產(chǎn)量下降，同樣導(dǎo)致美國(guó)煤炭開(kāi)采行業(yè)就業(yè)率大降42%。
“2018年，美國(guó)采煤行業(yè)就業(yè)人數(shù)由2011年的9.2萬(wàn)人下降至5.4萬(wàn)噸，其中阿巴拉契亞地區(qū)降幅最為明顯?！痹搱?bào)告顯示。
能源信息署表示，2008年美國(guó)在運(yùn)營(yíng)煤礦為1458座，煤炭產(chǎn)量為12億噸，而2018年，美國(guó)在運(yùn)營(yíng)煤礦下降至679座，共生產(chǎn)煤炭7.56億噸，十年間阿巴拉契亞地區(qū)煤炭產(chǎn)量減少了近二分之一。
