據(jù)路透社報(bào)道，全球主要煤炭出口國(guó)哥倫比亞日前發(fā)布數(shù)據(jù)稱(chēng)，受主要煤礦產(chǎn)量下降以及干旱影響，2019年，哥倫比亞煤炭產(chǎn)量同比下降2%，至8220萬(wàn)噸。
數(shù)據(jù)顯示，2018年，哥倫比亞煤炭產(chǎn)量曾創(chuàng)下歷史紀(jì)錄，然而，2019年，由跨國(guó)礦企必和必拓、嘉能可及英美資源三家合資，在哥倫比亞La Guajira省建設(shè)的Cerrejon煤礦項(xiàng)目擴(kuò)建被叫停。同時(shí)，根據(jù)哥倫比亞環(huán)境要求，為減少煤炭生產(chǎn)帶來(lái)的灰塵污染，在高溫條件下露天煤礦開(kāi)發(fā)也需要降低生產(chǎn)強(qiáng)度。因此，哥倫比亞煤炭產(chǎn)量整體下滑。
哥倫比亞國(guó)家礦業(yè)署主席Silvana Habib表示：“哥倫比亞煤炭工業(yè)已經(jīng)到了分岔路口。2019年動(dòng)力煤價(jià)格出現(xiàn)大幅下滑，從2018年的82.5美元/噸降至51.4美元/噸?！?br />
