摘　　要：为达到综采工作面安装作业空间要求,郑新公司芦沟煤矿三五井21051综采工作面安装前,采用工字钢对棚支护,对切巷进行二次扩巷,加大支护断面,增加有限作业空间,以满足综采工作面安装安全条件,保证安装作业的安全性和实用性,具有一定的借鉴和推广价值。In order to meet the requirements for the installation space of the fully-mechanized mining face,the author introduces the application of I-steel double-shed support before the installation of the fully mechanized mining face,and proposes the secondary expansion of the cutting roadway,meeting the installation safety conditions by increasing the support section and the limited working space,which can ensure the safety and practicality of the installation operation with certain reference and promotion value.
