摘　　要：回顾了近50 a来美国长壁开采技术从鲜为人知到成为世界标准的发展历程,重点阐述了自动化技术在长壁开采装备中的应用和发展.自动化技术从1984年开发电液控支架开始,一直持续应用.自动长壁系统于1995年正式投入生产,随着传感器技术和物联网的发展,自动化开采技术逐步改进完善,其发展的重点一直集中在设备可靠性的提高、矿工的健康和安全以及生产,包括粉尘控制技术、接近传感器、防撞技术和远程控制方面.自动化分为单一设备自动化和长壁开采系统自动化,长壁开采系统的自动化发展分为采煤机牵引支架前进系统、半自动化长壁开采系统和远程控制采煤机3个阶段.This paper reviews the development of U.S. longwall mining from an unknown to became the world standard in the past five decades with emphasis on automation. Automation began with the development of electrohydraulic shields in 1984 and continue to present. Introduction of automated longwall system occurred in 1995 and step-to-step improvement continues to present following the development of sensor technology and internet of things(IOT). Since then, emphasis on new development has been concentrated on the improvement of equipment reliability, miner’s health and safety as well as production, including dust control techniques, proximity sensor, anti-collision and remote control. Automation is classified into two categories: automation of individual face equipment and automation of longwall system. The automation development of longwall system is divided into three stages: Shearer-initiated-shield-advance(SISA), semi-automated longwall system, and remote control shearer.
