今年以來電力燃料供應總體平衡，電煤價格高位波動。上半年，全國規模以上煤礦原煤產量增長3.7%，全國煤炭進口量增長5.7%，全國電廠發電及供熱消耗煤炭增長3.4%，全國電廠存煤總體處于高位，電煤供應總體平衡。對于下游的礦山機械企業起到很大推動作用，上半年礦山機械企業整體效益良好。

山東礦機煤炭機械貢獻利潤大
　　山東礦機近日披露半年度業績預告，公司上半年預計實現歸屬于上市公司股東的凈利潤為11000萬元至13500萬元，同比增長47.99%～81.63%。公司表示，報告期內，國內煤機市場行情較好，公司主營業務中的煤機產品業務量增加，銷售收入、利潤率上升。山東礦機2018年實現營業總收入18.7億元，同比增長35.6%；實現歸屬于母公司所有者的凈利潤1.5億元，同比增長113.9%；每股收益為0.09元。本報告期內，國內煤機市場行情較好，公司主營業務中的煤機產品業務量增加，銷售收入、利潤率上升。
　　
三一國際綠色開采增速提效
　　三一國際日前發布盈利預告，預期2019年上半年度凈利潤較2018年半年度將取得大幅增長。對于業績增長的原因，三一國際在公告中表示，2019年上半年，隨著煤機設備更新替換需求持續釋放、以及煤炭行業加速推進智慧化、無人化及綠色高效開采，公司煤機產品訂單大幅增加，綜采產品、掘進機競爭力和市場份額持續提升，進而帶動煤機板塊收入大幅增長。港機方面，公司大型港機品牌影響力持續提升，相繼進入國內主流港口及多個內河碼頭，大型港機收入也實現大幅增長。
　　在國際市場拓展方面，三一國際也是成效顯著。記者從公司了解到，25臺正面吊日前已正式交付印度集裝箱公司，分布在客戶最重要、業務量最繁忙的7個堆場，并憑借可靠性高、油耗經濟性好、易維護保養等特點，受到客戶的贊許。據了解，三一正面吊目前在印度市場的占有率已達45%。三一國際在盈喜公告中表示，公司成功突破國際港口大客戶并簽訂戰略合作協議及訂單；小型港機在亞澳、印度、印度尼西亞、美國、歐洲等區域的國際銷售持續增長；綜采產品在烏克蘭也實現重大突破。
　　此外，三一國際堅持研發創新戰略，不斷優化產品性能和質量，提升市場競爭力。公司各類自動化、電動化新品相繼投放市場，帶來新的利潤增長點。其中SKT90S系列寬體車憑借出色的性能，獲得礦山客戶的高度認可，拉動礦用車輛收入大幅增長。
　　
林州重機利潤略減少
　　林州重機近日發布2019年上半年業績預告，預計凈利最高可達600萬元，比上年同期減少90.90%。
　　據了解，本次業績變動的主要原因是，公司全資子公司林州重機林鋼鋼鐵有限公司受環保限產，使得報告期內產品產銷、營業收入和凈利潤減少。公司全資子公司林州重機礦建工程有限公司部分合作項目到期，項目總量減少，致使營業收入、凈利潤減少。
　　企業公告顯示，從整個煤炭行業來看，根據國家統計局數據，煤炭開采與洗選業固定資產投資從2016年開始邊際改善，2018年三季度實現5年以來的首次正增長，同比增長2.1%，迎來正增長拐點。
