在黑龙江龙头煤企龙煤集团，记者看到，企业新建成5个智能化采煤工作面，配套升级32项无人值守生产辅助系统，并完成1251台套关键 设备更新——涵盖生产运输、监测监控、灾害防治及智能化控制等领域。这次改造推动采煤机械化率跃升至99.5%，高危岗位人员压缩90%， 人身伤害风险大幅降低，安全效益实现质的飞跃。 中煤协会数据显示，全国已建成智能煤矿907处、智能工作面1806个，智能开采产能占比首超50%，替代1.6万余个高危岗位。 央视网消息：中国煤炭工业协会日前公布今年上半年煤炭生产情况。数据显示，电煤供应稳定有序。 中国煤炭工业协会数据显示，1—6月，规模以上工业原煤产量24.0亿吨，同比增长5.4%。6月份，规模以上工业原煤产量4.2亿吨，同比增 长3.0%，日均产量1404万吨。原煤生产平稳增长。在进口煤方面，今年上半年，全国共进口煤炭2.22亿吨，同比下降11.1%。中国煤炭工业协 会新闻发言人张宏表示，全国煤炭生产继续保持稳定增长的态势，电煤供应稳定有序，电煤库存继续保持较高的水平，能够满足迎峰度夏期间 电煤的稳定供应和保障稳定。 全国煤炭智能开采产能占比首超50% 记者从中国煤炭工业协会了解到，全国智 ...

受装备技术成熟度低、工人劳动强度大、开采难度大等因素影响，极薄煤层资源开采率低，资源浪费严重。以陕煤集团黄陵矿区为例，井田范围 内分布着大量厚度仅0.6米至1.5米的煤层。极薄煤层占全矿区可采储量50%左右，但长期面临"采得出但采不好"的困境。 记者3月28日从中国煤炭科工集团（以下简称中国煤科）获悉，由中国煤科上海研究院研制的全国首个极薄煤层高效智能采煤机日前成功投入应 用。 在陕煤集团黄陵矿区地下百米处，煤层厚度仅0.78至1.3米的逼仄空间里，随着智能开采装备的流畅运行，"乌金"源源不断地被输送到传送带上。 全国首个极薄煤层高效智能采煤机投入应用 据悉，我国薄煤层煤炭资源储量巨大，约占煤炭总储量的20%，高达3500亿吨，开采量仅占我国煤炭总产量的7%。随着易于开采的中厚煤层不断 减少，推动薄煤层乃至极薄煤层开采已成为煤炭行业的当务之急。 全国首个极薄煤层高效智能采煤机投入应用 "为破解这一行业难题，我们为采煤机创新设计了悬机身式传动系统与双截割电机结构，让采煤机在0.78米极限高度下仍能灵活作业。"该项目负 责人魏升介绍，研发团队采用中压变频技术为设备"瘦身"，使采煤机在起伏不平的狭长巷道中顺畅运行。 ...
