摘要
煤层底板采动破坏深度的研究对底板水害防治和瓦斯抽采具有重要意义,是煤炭开采研究中极为重要的课题之一,大量学者对其开展了研究并取得了显著成果。文章基于前人所作的工作对煤层底板采动破坏深度计算方法的研究进展进行了综述,介绍了理论计算、现场探测、数值模拟和相似材料模拟四种常用的底板采动破坏深度计算方法,系统地梳理了各研究方法的原理、计算过程以及前人所作的工作,并对四种方法的发展前景进行了展望,旨在能够为相关研究提供一定的参考。
The research on mining failure depth of coal seam floor is of great significance to the prevention and control of floor water damage and gas drainage. It is one of the most important topics in research of coal mining. A number of scholars have carried out research on it and made remarkable achievements. Based on the work of predecessors, this paper summarizes the research progress of calculation methods of mining failure depth of coal seam floor, introduces four calculation methods of mining failure depth of coal seam floor, including theoretical calculation, on-site detection, numerical simulation and similar material simulation, systematically combs the principle, the calculation process of each research method and the work of predecessors, and the development prospect of the four methods is prospected, the purpose is to provide some reference for related research.
