摘要
矿产资源开采对国家安全和经济至关重要,随着浅部矿产资源逐渐减少,深部开采已上升为国家战略。充填采矿法因其安全性高和对地表环境影响较小等优势,已逐渐成为地下开采的首选方法。确定充填体的合理强度是解决充填采矿安全和经济平衡问题的关键,是充填采矿技术成功应用和健康发展的核心问题。论文梳理了胶凝剂、灰砂配比、充填骨料、养护环境、接触面特性等因素对充填体强度的影响规律,归纳了经验类比法、力学模型法、数值分析法、人工智能法等充填体强度设计方法,综述了充填体强度需求研究现状,提出了深部充填体强度需求计算新思路。旨在完善深部充填体强度需求计算理论,优化矿山充填体强度设计,推动深部金属矿山充填开采的研究与应用。
The exploitation of mineral resources is vital to national security and the economy,and with the gradual decline of shallow mineral resources,deep mining has risen to the level of a national strategy.Backfill has gradually become the preferred method of underground mining due to its advantages such as high safety and low impact on the surface environment.Determining the reasonable strength of the backfill is the key to solving the problem of balancing the safety and economy of backfill mining,and it is the core issue for the successful application and healthy development of backfill mining technology.The influence of factors such as cementitious agents,lime sand ratio,backfill aggregates,curing environment,and contact surface characteristics on the backfill strength are sorted out.The backfill strength design methods such as empirical analogy,mechanical model,numerical analysis,and artificial intelligence are summarized.The current research status of backfill strength requirement are summarized,and new ideas suitable for calculating the deep backfill strength requirement is proposed.It aims to improve the calculation theory of deep backfill strength demand,optimize the backfill strength design,and promote the research and application of deep metal mine backfill mining.
