膏体充填开采法地表沉降技术研究

Research on Paste Filling Mining Method Surface Subsidence Technology

焦作煤业(集团)有限责任公司韩王煤矿主要是采用膏体充填采煤技术来解放建筑物下压煤,膏体充填可以有效地控制地表沉陷,能够减小地表移动变形,减少地表破坏范围,但是也不能完全控制开采区域上覆岩层的变形、移动和破坏。在此条件下,对充填开采的地表开采沉陷技术进行研究,能对于今后充填开采对地表构筑产生的影响作出准确预测和评估,对矿井的正常生产、优化开采方案和整体规划有重要的指导意义。

Jiaozuo Coal （Group） C0．, Ltd. Hanwang Mine mainly takes paste filling mining technology to liberate the coal under buildings. Paste filling can effectively control subsidence, reduce ground movement and deformation, and reduce the surface damage area. But it can＇ t totally control the deformation, movement and damage of the overlying rock in the mining area. In this situation, to study the surface subsidence technology in filling mining is helpful for predicting and evaluating the effect of filling mining on surface building. It has guiding significance for the normal production of the mine and mining scheme and overall planning antimization.
