| 摘 要： | 充填开采是解决煤矿开采造成的环境问题,控制地表沉陷的有效技术途径之一.通过分析地表沉陷的形成过程及控制机理,提出了充填开采控制地表沉陷的空隙量守恒理论,推导出了地表沉陷盆地体积计算公式.依据该理论进一步提出了控制地表沉陷的技术途径,包括提高采空区的充填率、提高充填料浆及充填体的物理力学性能及增大上覆岩层滞留空隙体积等.工程实践表明,充填开采控制地表沉陷的空隙量守恒理论在煤矿膏体充填开采实践中得到了成功应用.

| Abstract: | Backfilling mining is an effective technical approach to solve the environmental problems and control surface subsidence caused by coal mining.The theory of space conversation for strata control in backfilling mining was put forward and the formula to calculate the surface subsidence volume was derived through the formation process analysis and the control mechanism of surface subsidence.Based on the theory,the technical approaches for subsidence control in backfilling mining were also put forward.The techn... |
