在 12040 工作面地表布设观测点,使用RTK测量地表观测点坐标变化,研究工作面推进过程中地表移动变形规律.建立数值模拟模型,模拟工作面推进过程中地表下沉,得出随推进距离的增加,地表沉陷逐渐呈现近似对称分布形式.综合现场观测情况及数值模拟结论,结果基本吻合.
Research on the Surface Movement and Deformation Law of Complex Coal Seams in Yunding Coal Industry
Set up observation points on the surface of the 12040 working face,use RTK to measure the coordinate changes of the surface observation points,and study the law of surface movement and deformation during the advancement of the working face.Establish a numerical simulation model to simulate the surface subsidence during the advancing process of the working face,and obtain that as the advancing distance increases,the surface subsidence gradually presents an approximate symmetrical distribution form.Based on the comprehensive on-site observation situation and numerical simulation conclusions,the results are basically consistent.
