在叙述陕北生态脆弱地区采煤引起的地表移动变形分布的基础上,从地表移动变形影响因素、采煤沉陷假说、地表沉陷预测、地裂缝机理及防治措施5个方面评述了该区地表移动变形的研究现状,可为生态脆弱矿区煤炭资源可持续开发提供参考。
Based on the description of the surface deformation caused by coal mining in ecologically fragile areas of northern Shaanxi, this paper reviews the effects of surface movement and deformation, coal mining subsidence hypothesis, surface subsidence prediction, ground fissure mechanism and control measures. The research status of deformation can provide a reference for sustainable development of coal resources in ecologically fragile mining areas.
