摘　　要：以淮南张集煤矿1111(1)运输顺槽的施工情况为例,阐述了锚杆(索)梁网联合支护在淮南新区厚复合顶煤巷中的应用情况,并分析了组合梁理论在煤巷锚杆(索)梁网联合支护中的应用机理,煤巷锚杆(索)梁网联合支护中顶板岩层受力和离层情况。It was illustrated by an example in the 1111 （ 1 ） headentry of Zhangji coal mine Huainan. The usage of bolt （cable） beam net timbering in thick compound roof coal heading in new developed area of Huainan are explained .The theory of compound beam is analysed in this article too.The theory of compound beam is roof layer＇s bearing capability and roof＇s absciss layer analysis with bolt（cable） beam net timbering in coal heading.
