摘　　要：详细介绍了我国厚煤层开采技术现状与发展历程,以及我国在放顶煤开采和大采高开采方面所取得的突出成绩。指出对于厚煤层开采要根据煤层条件和技术条件等采用合适的开采方法。随着开采煤层厚度和开采强度的增加,目前也遇到了提高煤炭资源回收率、支架合理选型、瓦斯运移规律与防治技术等新的课题,迫切需要解决。This paper introduces the state of the art and the development of thick seam mining techniques in details and the prominent achievements in top-coal caving and large cutting height workface in China. It is pointed out that proper mining method shall be adopted according to the thick seam coal mining conditions and technical conditions. With the increase of coal seam thickness and exploitation degree, many issues need to be resolved imminently, such as improving the recovery rate of coal resources, selection of proper support method, and gas movement law and control techniques.
