精品文档---下载后可任意编辑铁路下综采放顶煤地表沉陷规律及其变形控制措施讨论的开题报告摘要随着我国经济的不断进展和城市化进程的加快，对煤炭的需求日益增加。然而，目前我国的煤炭开采主要依赖于传统的地下采矿方式，这种方式存在安全风险、破坏环境等问题，严重限制了煤炭采掘的进展。因此，随着综合采矿技术的不断进展，煤炭开采方式也在不断改进和创新。本文针对铁路下综采放顶煤地表沉陷规律及其变形控制措施开展讨论。首先，通过文献资料的分析，介绍了综合采矿的基本概念以及其在煤炭开采领域的应用情况。接着，介绍了综采放顶煤的采掘过程及其引起的地表沉陷和变形问题。然后，利用数学和物理模型，从有限元方法、构造力学等角度分析了地表沉陷的形成机制及规律。最后，针对综采放顶煤地表沉陷和变形问题，提出了相应的控制措施，以减少对周围环境的影响，确保安全生产。本讨论的意义在于深化探究铁路下综采放顶煤地表沉陷规律及其变形控制措施，为煤炭开采技术的进一步完善提供了参考和依据。关键词：综合采矿；放顶煤；地表沉陷；有限元方法；构造力学；变形控制AbstractWith the continuous development of China's economy and the acceleration of urbanization process, the demand for coal is increasing day by day. However, the current coal mining in China mainly relies on traditional underground mining methods, which has safety risks and environmental damage problems, seriously restricting the development of coal mining. Therefore, with the continuous development of integrated mining technology, coal mining methods are also constantly improving and innovating.This paper focuses on the study of the law of surface subsidence and deformation control measures of top coal caving in underground comprehensive mining under railways. Firstly, the basic concept of comprehensive mining and its application in coal mining industry are introduced through literature analysis. Then, the coal mining process of top coal 精品文档---下载后可任意编辑caving and the surface subsidence and deformation problems caused by it are...
