摘要
针对黄土沟壑区地形及采矿条件,采用大量野外地质调查手段,研究了黄土沟壑区地裂缝发育规律,研究结果表明:采动地裂缝分为边界裂缝和动态裂缝,其中边界裂缝落差最大,动态裂缝在超前发育阶段落差最大。沟谷处裂缝较少,坡体处裂缝较多,其中下坡方向产生的裂缝明显大于上坡开采,且易形成塌陷槽。
For the terrain and mining condition of loess gully region, a large number of geological survey methods were used to study the law of ground fissure development. The results show that： ground fissure include boundary fissure and danymic fissure, in which the biggest fall developed in boundary fissure and in advance stage of danymic fissure; less fissure developed in valley and more fissure developed in slope, in which the fissure developed caused by mining in downhill is significantly greater than the uphill′s and easily formed collapse groove.
