对煤炭沟井田1-1′地质剖面煤层开采覆岩变形进行了有限元数值模拟分析.从岩体的本构关系入手,选取岩体参数,概化和建立工程地质模型,从而获得煤层开采中顶板岩体位移变化规律特征,分析结果表明,随着该区煤层的开采,会引发地面塌陷、斜坡滑坡和地裂缝等地质灾害,其结论对生产实践具有指导作用.
對煤炭溝井田1-1′地質剖麵煤層開採覆巖變形進行瞭有限元數值模擬分析.從巖體的本構關繫入手,選取巖體參數,概化和建立工程地質模型,從而穫得煤層開採中頂闆巖體位移變化規律特徵,分析結果錶明,隨著該區煤層的開採,會引髮地麵塌陷、斜坡滑坡和地裂縫等地質災害,其結論對生產實踐具有指導作用.

Finite element numerical simulation was used to analyze overburden deformation of 1-1′ geologic section coal seam of Meitangou mine field. Based on constitutive relation of rock mass, parameters of rock mass were selected, and an engineering geological model was established so as to acquire laws and characters of roof rock mass displacement in coal seam exploitation. The result indicated that ground collapse, landslide, ground fissure and the like geological disasters would occur as the coal seam was exploited. The conclusions could guide production practice.
