深部工作面冲击地压防治技术研究

Study on The Prevention and Control of Rock-burst in Deep Working Face

针对千米采深的采煤工作面掘进及回采期间面临的巨大的防冲压力,通过严格实施大直径钻孔卸压、煤体爆破卸压、煤层注水等卸压解危措施,保证安全生产的同时,也积累了相关的防冲工程施工参数,对深部工作面采取针对性冲击地压防治措施具有指导意义。

For km deep mining face during the excavation and stoping face tremendous impingement pressure, through strict implementation of large diameter borehole pressure relief, unloading blast in coal and coal seam water injection pressure relief XieWei measures to ensure safety in production at the same time, also accumulated the related prevention engineering construction parameters and to targeted impact earth pressure on deep working face has guiding significance for prevention and control measures.
