全尾砂充填矿山地表移动研究
|
摘要
矿区地表沉降对开采区地表的可持续发展有着重要的影响,会宝岭铁矿利用全尾砂充填技术来减少采空区地表塌陷,但是回采和充填过程仍对地表有一定的破坏。本文利用GPS-RTK技术以及水准方法来监测会宝岭铁矿开采区域所布设地表移动观测站,分析监测成果并确定开采区域的地表移动特征及移动参数,将概率积分方法用于预测变形并将其与测量数据进行比较。研究表明全尾砂充填下开采区域地表下沉轻微,变形造成的破坏较小。
The surface subsidence of the mining area has an important impact on the sustainable development of the mining area.Huibaoling iron mine use the full tailings filling technology to reduce the surface subsidence of the goaf area,but the mining and filling process still have certain damage to the surface.This paper will use GPS-RTK technology and horizontal observation to observe the surface movement monitoring station of the iron mine,analyze the basic law and movement parameters of surface movement in the mining area according to the observation results,and use probability integral method to predict deformation and compare with the measured data.The results show that the surface subsidence is well controlled and the destruction of deformation is small.
