| 摘 要： | 融冠矿业西矿区▽1 158以下水平将改用无底柱分段崩落法回采,为保证回采工作顺利进行,需对在▽1158水平的众多采空区实施强制放顶,从而形成足够厚度的覆盖层。针对典型采空区,通过数值模拟分析了采空区稳定性,结合现场条件提出类VCR法处理方案,即通过采空区放顶工程相关爆破参数设计,实施一次起爆放顶工艺。实践结果表明,类VCR法是处理采空区切实有效,是对常规放顶方法的重要补充与改进。 |

| Abstract: | West mining area of Rongguan mining will switch to pillarless sublevel caving method in mine recovery under ▽1 158 level.In order to ensure the smooth progress of projects,the 6 gobs in ▽1 158 level should be eliminated and to form covers.According to typical gob,using ANSYS soft-ware to analysis the stability of gobs,combining with spot conditions we propose the similar VCR method.Drawing on experiences in handing previous goaf,detonate explosive depending on designed blasting parameters.The results show that similar VCR method is sensible and successful. |
| Keywords: | goaf similar VCR method stability analysis caving engineering blasting parameter |
