中文摘要：

以平煤六矿新建斜井巷道穿越采空区为工程背景,采用数值计算分析、现场监测等方法研究了采空区覆岩破断及其矿压显现特征.针对斜井穿越采空区段围岩破碎的特点,提出了金属网＋全断面U型钢＋反底拱连锁梁＋浇筑混凝土＋壁后注浆的支护方案,其通过“双壳支护”形成的内外承载结构能在很大程度上提高采空区破碎岩体的整体性.现场监测表明：斜井穿越采空区段巷道两帮的移近量为26 mm,顶底板移近量为47 mm,达到了有效控制巷道围岩变形的目的.

英文摘要：

Based on the engineering background of new inclined roadway through mined - out area in the Pingdingshan Sixth Mine, the numerical analysis and field monitoring are used to study the over- burden rock fracture characteristics and its mine pressure in mined -out area. Aiming at the charac- teristics of broken surrounding rock in mined - out area when the inclined roadway passed through this area, the supporting plan of metal net ＋ whole section U - shape steel ＋ bottom - arch linkage girder ＋ concreting ＋ backfill grouting is put forward. The internal and external bearing structure formed by ＂Double - shell support＂ can largely improve the integrity of broken rock mass in mined - out area. Field monitoring shows that in the mined -out area passed through by inclined roadway convergence of ribs is 26 mm, and convergence between roof and floor is 47 mm, and the goal of effectively con- trolling roadway surrounding rock deformation is achieved.
