薄煤层开采由于采高低、空间狭小，长期面临劳动强度大、自动化程度低、经济效益差等困境。记者7月3日获悉，中国煤炭科工集团有限公司旗下宁夏天地奔牛实业集团有限公司日前发布薄煤层等高开采关键技术及成套装备，标志着我国薄煤层智能化开采实现重大突破。

Due to the low height and narrow space of the thin coal seam mining, it has long faced difficulties such as high labor intensity, low automation level and poor economic benefits. On July 3rd, reporters learned that the Ningxia Tiandi Beniu Industrial Group Co., Ltd., a subsidiary of China Coal Science and Technology Group Corporation, recently released key technologies and complete sets of equipment for high-level thin coal seam mining, marking a major breakthrough in the intelligent mining of thin coal seams in China.

我国薄煤层资源储量丰富，广泛分布于80多个矿区，工业储量约占煤炭总储量的20%。当前，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安全高效开采，已成为煤炭行业高质量发展的当务之急。薄煤层等高开采关键技术及成套装备正是应相关需求研发而成的。

Our country has abundant resources of thin coal seams, which are widely distributed in over 80 mining areas and account for approximately 20% of the total coal reserves. Currently, as the easily accessible medium-thick coal seams are continuously decreasing, promoting the safe and efficient mining of thin coal seams and even extremely thin coal seams has become an urgent task for the high-quality development of the coal industry. The key technologies and complete sets of equipment for high-level coal mining, such as thin coal seams, have been developed in response to these demands.

装备研发团队创新构建等高开采工艺和装备体系，研制截割功率550千瓦的等高式采煤机。该装备集成刮板输送机、高承载能力的轻量化液压支架以及高度集成的智能化远程控制系统。在技术创新方面，装备的过煤空间较同规格常规产品增大80%，能够在13.5米/分钟的割煤速度下常态化运行，可实现工作面快速推进、线缆智能保护和远程无人作业，开采效率提升25%以上。

The equipment research and development team innovatively constructed an advanced mining process and equipment system, and developed an equal-height coal mining machine with a cutting power of 550 kilowatts. This equipment integrates a scraper conveyor, a lightweight and high-capacity hydraulic support, and a highly integrated intelligent remote control system. In terms of technological innovation, the coal-cutting space of this equipment is 80% larger than that of conventional products of the same specification, and it can operate normally at a coal-cutting speed of 13.5 meters per minute. It can achieve rapid advancement of the working face, intelligent protection of cables, and remote unmanned operation, with a mining efficiency increase of over 25%.

“该套装备成功破解小空间与大功率的长期矛盾，解决了传统斜切进刀效率低、设备适配性差、人工安全风险高等痛点。其推广应用将有效释放薄煤层资源开采潜力，推动煤炭行业向安全、高效、智能、绿色方向转型。”宁夏天地奔牛实业集团有限公司董事长闫志民说，“本次科技成果的成功研制，离不开宁夏科技厅长期的悉心指导以及专项经费、产业政策的有力支撑。”

This set of equipment successfully resolves the long-standing contradiction between small space and high power, and addresses the problems such as low efficiency of traditional inclined cutting, poor equipment adaptability, and high safety risks for manual operations. Its wide application will effectively unleash the potential for thin coal seam mining, and promote the transformation of the coal industry towards safety, efficiency, intelligence, and sustainability. Yan Zhimin, the chairman of Ningxia Tian Di Ben Niu Industrial Group Co., Ltd., said, "The successful development of this scientific and technological achievement would not have been possible without the long-term meticulous guidance from the Ningxia Science and Technology Department, as well as the strong support from special funds and industrial policies."

“近年来，我们持续强化关键技术攻关和科技成果转化，自2017年以来凝练实施产业重大科技攻关、科技型企业培育等‘五大科技创新行动’，特色创新成效初显。”宁夏科技厅副厅长马龙介绍，宁夏科技厅通过加强创新平台绩效评价、落实科创成果奖补支持、组建创新联合体等措施，推动企业在矿山机械领域取得持续突破。

In recent years, we have continuously strengthened efforts in key technology research and development and the transformation of scientific and technological achievements. Since 2017, we have formulated and implemented five major 'innovation-driven actions' including major scientific and technological research in the industry and the cultivation of technology-based enterprises. The distinctive innovation achievements have begun to emerge. "Mao Long, the deputy director of the Ningxia Science and Technology Department, introduced that through measures such as strengthening the performance eva luation of innovation platforms, implementing support for scientific and technological achievements, and establishing innovation consortia, the Ningxia Science and Technology Department has promoted continuous breakthroughs by enterprises in the field of mining machinery."
