摘要
基于矿井的恶劣环境,为了精确定位采矿活动对地层沉降可能造成的影响,找出运动规律,在相似材料模型的基础上利用自动网格法对井下开采后的位移进行了精确测量,并且详细讨论了自动网格法的实验步骤,提出了一种新的图象匹配矫正方法,并利用井下开采前后的实际位移数据说明了这种方法的可行性和不足。
The underground mining circumstances is bad, in order to accurately locate the stratum subsidence due to underground mining and discover the movement rule of stratum, the rock displacement brought by exploring was measured accurately using automated grid methods based on the similar material model. This paper detailedly discusses the experimental procedures of the automated grid methods, advances a kind of new image - matching rectifying method, and makes use of actual data of the displacement to explain the feasibility and insufficiencies of this method.
