综合机械化固体(废弃物)充填采煤技术能用于低成本、安全、高效回收“三下”压煤和煤柱资源,具有提高煤炭资源回收率,循环利用矿区固体废弃物,保护矿区土地、水资源和环境等优点.在简述固体充填采煤方法及其岩层控制效果的基础上,重点比较了该方法与一般长壁综采在采场矿压控制原理和支架设计理念等方面的显著差异;进一步完善了用于分析岩层移动和地表沉陷等规律的固体充填采煤的等价采高矿压模型;基于提出的固体充填采煤液压支架设计理念,给出了用于分析支架主动加载对顶板变形移动控制的采场矿山压力力学模型,根据半无限平面上作用集中力的经典弹性力学Flamant解,推导得到了计算支架主动力作用引起的采场顶板变形位移曲线的解析解,对完善固体充填采煤基础理论起到了一定的推进作用.
Integrated mechanized solid (waste) filling coal mining technology can be used for low-cost, safe and efficient recovery of “three under” coal and coal pillar resources, with the increase of coal resource recovery, recycling of solid waste in mining areas, protection of mining Land, water resources and environment, etc. On the basis of a brief description of the solid filling and coal mining methods and the control effects of rock strata, this method and the general longwall fully mechanized mining are mainly compared in terms of the stope pressure control principle and the design concept of the scaffold ; Further perfecting the equivalent mining pressure model for solid filling coal mining that is used to analyze the law of rock movement and surface subsidence; based on the proposed design concept of solid filling coal mining hydraulic support, According to the classical elastic mechanics Flamant solution of concentrated force acting on the semi-infinite plane, an analytical solution for calculating the deformation curve of the stope roof caused by the main force of the support was derived. It has played a certain role in promoting the basic theory of solid filling coal.
