| 摘 要： | 以回坡底煤矿1021巷道底鼓现象为研究背景,通过数值模拟,研究了1021巷道底板围岩的水平变形量、垂直变形量,并实施了相应的底鼓防治技术.现场监测结果表明,与未经过底鼓防治处理的巷道相比,防治段巷道底板变形量大幅减小,验证了底鼓防治技术是可行的.

| Abstract: | Taking the floor heave phenomenon of 1021 roadway in Huipodi Coal Mine as the research background,this paper studied the horizontal deformation and vertical deformation of floor surrounding rock of 1021 roadway by numerical simulation.The corresponding floor heave prevention technology was implemented.The field monitoring results show that,compared with the roadway without floor heave control treatment,the floor deformation of the prevention section is significantly reduced,which verifies that the floor heave prevention technology is feasible. |
