摘　　要：复杂特厚煤层6.2 m一次采全高大采高工艺优化是实现安全高效开采的关键技术之一。在大采高工作面(采高大于6.0 m)开采时,覆岩移动及矿压显现周期、强度、范围都发生明显变异。以羊场湾煤矿大采高为背景,根据实际煤层赋存条件和矿压显现规律,采用理论分析、数值计算、物理相似模拟等方法,优化确定回采工艺系统与参数。It＇s one of the key technologies for a safe and efficient mine to optimize the 6.2 m large high mining technology under complex environment. During large height mining face advancing （the mining height is higher than 6.0 m）, overlying strata movement, stress behavior cycle, strength, and scale alter obviously. Based on the ＂large height face of Yangchangwan coal mine, according to the occurrence condition of coal seam and the law of ground pressure, with theoretical analysis, numerical computing and physics simulation, the mining technology system and parameters are determined.
