以晋华宫矿12-3＃层2116巷为研究对象，综合运用理论分析和现场实测的手段，研究了大跨度 T 型交叉皮带巷的不停机贯通技术。结果表明：提前加固和防护为维持大跨度 T 型交叉口围岩的稳定和正常的输煤生产提供了强有力的保障；侧洞法施工技术和动态支护设计共同作用，使大跨度 T 型交叉皮带巷不停机贯通成为必然；矿压监测结果表明，整个贯通过程中，2116巷顶板下沉11.14mm，301盘区皮带巷顶底板移近量和两帮收敛量分别为6.6mm 和5.0mm，实现了大跨度 T 型交叉皮带巷的不停机贯通。
以晉華宮礦12-3＃層2116巷為研究對象，綜閤運用理論分析和現場實測的手段，研究瞭大跨度 T 型交扠皮帶巷的不停機貫通技術。結果錶明：提前加固和防護為維持大跨度 T 型交扠口圍巖的穩定和正常的輸煤生產提供瞭彊有力的保障；側洞法施工技術和動態支護設計共同作用，使大跨度 T 型交扠皮帶巷不停機貫通成為必然；礦壓鑑測結果錶明，整箇貫通過程中，2116巷頂闆下沉11.14mm，301盤區皮帶巷頂底闆移近量和兩幫收斂量分彆為6.6mm 和5.0mm，實現瞭大跨度 T 型交扠皮帶巷的不停機貫通。

Taking the 2116 roadway in layer 12 -3 #of Jinhuagong mine as research sample,study on the linkage technology for T -intersection beltway with large -scale while belt doesn't stop running integrated use of theoretical analysis and field measurement,the results show that:early reinforcement and protection provide a strong guarantee to maintain the rock of T -intersection beltway with Large -scale steady and normal coal production;it is very possible to linkage for T -intersection beltway with large -scale while belt doesn't stop running under the common of side drift method dynamic reinforcement technology;the mine pressure monitoring results show that the amount of roof and floor closer,the convergence between two sides of the beltway in 301 panel and the roof subsidence of 2116 roadway are 6. 6mm,5.0mm and 11.14mm during constructing,achieved the original object.
