摘　　要：为论证阳煤一矿8303(东部)工作面采用大采高工艺的科学性和可行性,根据对8310和8303(西)工作面大采高工艺的试采情况,分析了复杂条件下大采高综采的主要影响因素,通过对煤层上覆顶板厚度的稳定性、地形及地质条件的多变性以及构造发育的论证,建议将大采高工艺调整为综采综放工艺。In order to demonstrate science and feasibility of 8303(east)working face with large mining depth technology of No.1 Mine of Yangquan Mining Group,based on the tested mining of 8310 and 8303(west)with large mining depth,the influenced factors of large mining depth under complex geological condition were analyzed,the stability of upper overlying roof thickness,variability of geological conditions and tectonic development were demonstrated,the large mining depth technology was advised to adjust to fully mechanized caving technology.

关 键 词：采高控制 顶板多变性 构造发育 适应性
