摘　　要：鉴于7 m以上大采高综采工作面回采技术在国内还不太成熟,以神华神东煤炭集团补连塔煤矿12511(8 m)大采高综采工作面为例,分析了8 m大采高综采工作面回采过程中工作面防片帮技术及工作面两端头与巷道割煤过渡技术和工作面矿压显现情况等关键技术。In view of the fact that the mining technology of fully mechanized coal mining face with high mining height of more than 7 meters is still not mature in China, this paper takes the 12511（8 m） large mining height fully mechanized coal mining face of Shenhua Shendong Coal Group as an example, we analyze the key technologies including anti-rib spalling technology at working face, working face two ends and roadway cutting coal transition technology and strata behaviors of working face.
