黄陵二号煤矿井下采空区注浆处置煤矸石技术的应用研究

Discussion on the application of grouting and disposal gangue technology in the underground goaf of Huangling No.2 Coal Mine

煤矿大规模开采产生的大量煤矸石堆存,会造成生态破坏与环境污染。黄陵二号煤矿结合生产实际,从源头上入手,通过研究比选,确定了选用邻位注浆充填作为浆体充填技术。结果表明,该技术具有适应性强、灵活性高、投资低、对生产影响小等优点,适于黄陵二号煤矿采空区注浆处置矸石,建成后预计可取得良好的效益。

A large amount of coal gangue piled up produced by large-scale mining of coal mines has caused environmental pollution and ecological damage to the ecological environment.Huangling No.2 Coal Mine combined with the actual production,starting from the source,through research and selection,determined the selection of ortho-grouting filling as the slurry filling technology.The results show that this technology has the advantages of strong adaptability,high flexibility,low investment and low impact on production,and is suitable for grouting and disposal of gangue in the goaf of Huangling No.2 Coal Mine,and is expected to achieve good benefits after completion.
