摘要: 地下矿山在顶板稳固而难以自然冒落时,易形成大型采空区,产生较大安全隐患。 经分析矿山技术条件,对顶板的冒落特性进行研究,设计采用局部放顶与切顶弱化相结合的深孔 爆破诱导冒落法对特大采空区进行处理。经成功实施,该方案基本消除了特大采空区的安全隐 患,对相似工程具有参考价值。

Abstract: When the roof of underground mine is stable and difficult to fall naturally,it is easy to form a large goaf and produce a large safety hazard. By analyzing the technical conditions of the mine,the caving characteristics of the roof are studied,and the deep hole blasting induced caving method combined with local caving and roof cutting weakening is designed to deal with the large goaf. After successful implementation,the scheme basically eliminates the potential safety hazards of super-large goaf and has reference value for similar projects.

Key words: extra-large goaf, overhead caving, roof cutting weakening, induction caving
