摘要
总结了我国现有矿井采空区和巷道永久密闭技术,分析了常用无机材料充填密闭、有机材料充填密闭和混合材料充填密闭的特点和局限性,继而从复合新型充填材料、快速支模新工艺和轻型泵送充填新设备三方面展望了永久密闭技术的发展趋势,为相关研究提供借鉴和参考。
This paper summarized the existing mine goaf and roadway permanent sealing technology in my country,and analyzed the characteristics and limitations of commonly used inorganic material filling sealing,organic material filling sealing and mixed material filling sealing.The development trend of permanent sealing technology was prospected from three aspects and the new light-duty pumping and filling equipment,which provided reference and reference for related research.
