综采工作面大采高采煤方法的应用 【摘要】 煤炭是我国重要的基础能源和重要原料，是国民经济和社会发展的基础，随着我国经济的飞速发展，对煤炭工业的发展提出了更高的要求。近年来，随着综采设备制造技术的飞速发展，综采设备走向重型化、强力化和自动化，使设备的可靠性得到保证。有力的推动了大采高综采技术的发展，带来了新一轮采煤技术的革命，目前在河东、内蒙、晋城等矿区的厚煤层中使用大采高综采设备，实现了国内工效最高，吨煤成本最低的成果，极大地提高了煤炭市场的竞争力。因此，在煤炭企业生产中若地质条件和煤炭赋存条件允许的情况下应该优先考虑大采高采煤方法。 【关键词】：大采高；综采技术 In this paper：Coal is the important foundation energy and important raw materials in our country, is the foundation of the national economy and social development, with the rapid development of economy in our country, puts forward the higher request to the development of coal industry.In recent years, with the rapid development of fully mechanized equipment manufacturing technology, the fully mechanized equipment to ChongXingHua, powerful and automation, make the equipment reliability guaranteed.Powerfully promoted the development of the large mining height are broken compound mining technology, has brought a new round of coal mining technology revolution, now in hedong, Inner Mongolia, jincheng mining with large mining height are broken in thick coal seam fully mechanized equipment, has realized the domestic efficiency highest, the lowest cost of tons of coal, greatly improved the competitiveness of the coal market.Therefore, if the geological condition of the coal enterprise production and coal occurrence conditions allow should give priority to large mining height are broken coal mining method.
