摘要:
针对彬长生产服务区建筑群受采空区影响问题,应用数值模拟计算、覆岩变形理论分析方法,结合地表监测成果,综合计算分析了建筑群下107工作面综放开采采空区稳定性及其对建筑物的影响,分析结果表明,107工作面开采属于非充分采动,覆岩中洛河组、宜君组坚硬厚岩层对地表移动变形具有控制性的作用,由于坚硬关键层的整体变形作用,使得地表水平移动范围大于沉陷范围,地表建筑群下采空区已基本稳定。应用影响函数预计模拟方法预计分析了地表剩余移动变形,表明地表移动盆地已经处于基本稳定状态,地表剩余移动变形对建筑物影响很小。研究结果为彬长生产服务区建筑群下开采沉陷灾害治理提供了可靠地依据。
Abstract:
According to the mining affected buildings in Binchang production service area, based on numerical simulation, overburden deformation theory analysis and combined with surface monitoring results, the paper analyses stability of mine goaf and mining influence on buildings. The results showed that 107mining working face is subcritical extraction. Hard rock can controll movement and deformation of the surface. Due to the role of key layer, the range of horizontal movement is greater than subsidence range, thus mine goaf under buildings has been basically stable. Application of expected function simulation to analyze residual movement and deformation of surface, thus it indicates that the ground basin has been stable state, the residual movement and deformation have little effect on the buildings.It provides a reliable basis to the disaster management of mining subsidence in Binchang production service area.
