摘　　要：不规则综采工作面延面技术是综采工艺中一项复杂的工程。回采过程中,随着工作面的推进,工作面长度不断增加,上端头需要连续不间断延设输送机,安装液压支架,控顶方式始终处于动态变化中,通过科学分析、合理确定了待安装支架的位置和上端头的支护方式,达到了科学、快速、合理安装支架的效果。The irregular surface extension of fully mechanized coal mining face technology is a complex project in fully mechanized mining technology. The length of the working face increased along with the working face forward in the mining process, the belt of conveyor must be lengthened, and hydraulic support should be installed, so roof control method was changing all the time. Through scientific anal- ysis, the location of support and supporting way of working face＇s upper tip were determined reasonably. All this received scientific fast, and reasonable effects.
