薄煤层综采现状及对其发展展望研究摘 要：近年来，随着社会经济的快速发展，我国煤炭开采技术水平也有了显著的提高，这对国民经济的发展具有非常重大的意义。就目前我国煤炭开采情况来看，薄煤层开采对实现煤炭工业的可持续发展具有至关重要的作用。虽然薄煤层开采技术有了一定程度的提高、机械化采煤技术也有了一定程度的进步，但仍存在着一些问题。文章从综采配套设备和自动化远程控制两个方面对薄煤层开采技术进行了深入研究，提出了薄煤层自动化开采的工作模式，开发了既能满足一定生产能力，又能适应复杂生产环境的无人自动化、远程控制开采的开采体系及其工艺。通过对智能控制、网络传输、视频监测和远程通讯等关键技术的应用研究，建立起了薄煤层数字化无人工作面监控系统，基本实现了薄煤层综采工作面的无人化远程控制。关键词：薄煤层，综采，自动化，远程控制Abstract：In recent years, with the rapid development of social economy, Chinas coal mining technology has also been significantly improved, which is of great significance to the development of the national economy. On the current situation of coal mining in China, thin coal seam mining plays an important role in realizing the sustainable development of coal industry. Although the thin coal seam mining technology has a certain degree of improvement, mechanical mining technology has a certain degree of progress, but there are still some problems. In this paper, the thin seam mining technology is studied deeply from two aspects of fully mechanized mining equipment and automatic remote control. The paper puts forward the working mode of automatic mining of thin coal seam, and develops the system and technology of unmanned automation and remote control mining, which can not only meet the production capacity, but also can adapt to the complex production environment. Through the application research of intelligent control, network transmission, video monitoring and remote communication and other key technologies, the monitoring system of the digital unmanned working face of thin coal seam is established, and the unmanned remote control of the fully mechanized coal mining face is realized.Key Words: thin seam, fully mechanized, automation, remote control1 薄煤层研究背景薄煤层开采一直是困扰我国煤炭行业的技术难题，特别是极薄煤层综采技术的实现尤为困难。数据表明全国1.3m以下的薄煤层约占煤炭储量的19%，而开采比例只有7%。国内多数矿井采用普采或高档普采生产工艺，存在生产效率低、经济效益差、人员与设备安全性低等问题。另外，对一些薄、厚煤层并存的煤矿，由于薄煤层开采速度缓慢，使其下部的中厚煤层长期得不到及时开采，以至影响工作面的正常接替，而有的就只能被迫丢失一些薄煤层资源;随着大批煤矿中、厚煤层的资源开采，薄煤层的开采己提上日程。尽管部分矿井开展了薄煤层综采机械化研究，但受地质条件、开采方式
