摘　　要：结合陕西煤炭工业发展实际,介绍分析了长壁综合机械化采煤发展现状,提出必须根据煤层赋存条件和环境承载能力确定合理的开发强度;放顶煤开采经过20多年发展已形成系统的特厚煤层高产高效开采技术,当前的关键是必须进行本质安全开采研究;小煤矿开采方法需要规范化和提高机械化水平,以及总体提高我国煤炭资源采出率等问题等国内外研究信息。The paper makes a special effort to introduce development situation of longwall comprehensive mechanization mining, and indicates that reasonable developing strength must depend on formation conditions of seams and bearing capacity of environment. Top - coal caving has formed systematic mining technology with high production and high efficiency about special thick seams by twenty years developing. Mining of essential safety is the key to Top - coal caving at present. Mining methods of small coal mine need normalize and improve mechanization level. Improving low recovery rate of coal resource and enhancing research information is important to development of coal industry in our country.
