山区开采沉陷地表移动变形规律
Law of surface movement and deformation of mining subsidence in mountain area
摘要
Abstract
To study the movement principles of earth surface in mining subsidence area and improve accuracy of geological environment evaluation in mines,this paper conducted simulation experiments to reappear the subsidence engineering geological conditions of the strata and the process of surface collapse.The result shows that the location of turning point of subsidence curve in mountain area tends to move towards the upper direction of the hill.At the same time,the size and distribution of ground fissure have a relation to the changes of surface concave-convex.What's more,the scale and degree of surface movement deformation are decided by surface slope,thickness and features of surface soil.Our preliminary conclusion suggests that the L-shape fissure in surface rock stratum is benefitial for mine exploitation while the movement and deformation principles of earth surface in goaf proposed in this paper can help the protection and restoration of geological environment in mine area.关键词
