高产高效矿井建设，是我国煤炭工业科教兴煤战略的发展目标之一，也是煤炭企业步入高效率、高效益良性循环的重要途径。如何建设高产高效矿井？客观地讲，不同的地质条件和装备水平有着不同的目标和标准。煤炭科学研究总院耿兆瑞教授级高级工程师撰文，系统地介绍了美国科罗拉多州塞浦路斯煤炭公司隶属的二十英里矿高产高效的经验，并对其先进的采煤技术和装备进行了全面的剖析。这对于众多的煤炭企业而言，不失为最新的技术信息，相信能为广大现场工程技术人员和科研工作者提供借鉴和帮助。
High-yield and high-efficiency mine construction is one of the development goals of coal science and education in coal industry in our country. It is also an important way for coal enterprises to enter a virtuous circle of high efficiency and high efficiency. How to build high yield and high efficiency mine? Objectively speaking, different geological conditions and equipment levels have different goals and standards. Geng Zhaorui, a professor-level senior engineer at the General Administration of Coal Science, wrote an article systematically introducing the 20-mile high-yielding experience of Cyprus Coal Corporation of Colorado, USA, and thoroughly analyzed its advanced coal mining technologies and equipment. This for many coal companies, after all, the latest technical information, I believe for the majority of on-site engineering and technical personnel and research workers to provide reference and help.
