建筑物下宽条带开采方案研究

 针对策底河煤矿地质采矿条件及地表建筑物情况，在理论分析、地表移动变形预计的基础上，分析研究了建筑物下压煤宽条带开采方案及参数，并结合运用FLAC3D数值模拟计算对条带煤柱及岩梁稳定性进行了计算分析。结果表明，运用条带开采方案能有效控制地表移动变形值，满足保护地表建筑物的要求，解决了策底河矿建筑下安全采煤的技术难题。

Research on Scheme of Wide Strip Pillar under Buildings

The research clearly knew about geological mining and surface building settings of Cedihe colliery. It was elaborated key parameters and scheme of wide strip pillar under buildings combining with hybrid theoretical analyses and plans on surface movement and deformation. Simultaneously a field stability simulation about wide strip pillars and rock beams was gotten by numerical software FLAC3D. The result illustrated a significant behavior for wide strip pillar to protect buildings with validly controlling surface movement and deformation, which would offer valid approaches for safe and efficient excavation under buildings in the research area.
