我国开采沉陷学70年研究综述及技术展望

    70 year review and technical outlook on mining subsidence research in China

    • 摘要: 从覆岩破坏规律、地表移动变形规律,以及技术标准和学术专著等方面,回顾了开采沉陷学科的发展历程和取得的重要研究成果。在覆岩破坏规律方面,我国学者提出了岩体响应采动理论、关键层理论等,并总结归纳了裂隙带的形态特征和发育高度;在地表移动变形规律方面,我国学者提出了负指数函数法、概率积分法等计算方法,尤其是概率积分法广泛应用于地表沉陷预计;在技术标准和学术专著方面,我国开展了较为系统的建设工作,几经系统修订并实施,并出版了一系列学术专著。本文归纳总结了目前开采沉陷学研究中存在的难点问题,包括围岩介质属性、概率积分法局限性、综采(综放)“两带”高度和形态、地表残余移动变形特征与规律、动态地表移动变形特征和计算方法、地表观测站观测频率、相关规程对同一事项的技术要求不一致的问题。提出了学科今后研究工作的发展方向及建议,包括以覆岩运动全过程可视化为主要手段揭示开采沉陷的本质机理、以空间信息技术为主要手段完成数据的采集与处理。研究认为,只有认识到“采场矿压-岩层移动-开采沉陷”是一个有机统一的整体,才能准确地理解和描述开采沉陷。在不断继续补充完善已有研究成果的同时,有必要以新理论和新思想审视开采沉陷学,以新技术和新方法研究开采沉陷学,不断推动学科的深入发展。

       

      Abstract: This paper briefly reviews the development process and important research achievements of mining subsidence from the aspects of the law of overlying rock, the law of surface movement and deformation, technical standards and academic monographs. In terms of the law of overlying rock, Chinese scholars have proposed rock mass response mining theory, key layer theory, etc., and summarized the characteristics and height of fracture zones; in terms of the law of surface movement and deformation, Chinese scholars have proposed calculation methods such as negative exponential function method and probability integration method, etc., especially the probability integration method, which is widely used in predicting surface subsidence; in terms of the technical standards and academic monographs, China has carried out systematic construction work, which has been systematically revised and implemented several times; and published a series of academic monographs. This paper discusses the difficulties in current research on mining subsidence, including the properties of surrounding rock media, limitations of probability integration method, height and shape of the “two zones” of fully mechanized mining (fully mechanized caving), characteristics and laws of residual surface movement and deformation, dynamic surface movement and deformation characteristics and calculation methods, observation frequency of surface observation stations, and inconsistent technical requirements of relevant regulations for the same matter. And proposes suggestions for future research directions, including using visualization of overlying rock movement as the main means to reveal the essential mechanism of mining subsidence, and using spatial information technology as the main means to complete data collection and processing. The research results show that only by recognizing that “mining pressure-rock movement-mining subsidence” is an organic and unified whole, mining subsidence can be accurately understood and described. While continuously supplementing and improving existing research results, it is necessary to examine mining subsidence studies with new theories and ideas, study mining subsidence studies with new technologies and methods, and continuously promote the in-depth development of the discipline.
