针对深部特厚煤层巷道地应力高、 煤体承载能力弱、 顶板下沉量大、 两帮收敛严重等特点,以新巨龙煤矿2304N特厚煤层巷道为工程背景,运用现场调研和数值模拟相结合的方法,观测破坏关键位置,分析巷道变形原因,得出量化指标;采用理论计算与数值模拟相结合的方法,研究支护参数对其巷道控制影响规律,提出有针对性的控制方案.采用预应力锚杆、 金属网和钢带在围岩内形成加固区,改变围岩受力状态;使用长锚索和锚索梁锚固巷道顶板,控制顶板下沉;在顶角和两帮打设锚索,提高围岩抗剪切能力,控制两帮变形.通过上述“锚带网索联合支护”方案的现场实施,经现场监测和钻孔窥视验证了支护方案的有效性.“,”To some characters of high crustal stress, low bearing capacity of coal, seriously convergence of roof to floor and two sides of roadway with extra thick coal seam in deep, it tacking 2304N extra thick coal seam roadway as engineering background of Xinjulong coal mine, and then combined method of field survey and number simulation were applied, the influence principle of supporting parameters to roadway control, and some effectively schemes were put forward, and reinforce zone was formed within rock with pretension bolt, net and steel strip, the stress state of rock was improved, roadway roof was controlled by long length cable and cable bridge, roof subsidence was controlled. Surrounding rock shearing capacity was improving and then two sides deformation was controlled by cables layout at upper corner and two sides. And then the schemes were applied in field, the effectiveness of supporting scheme was verified by field monitoring and bore observation.
