榆林某煤矿采空区地表移动变形预测及其工程分区

Prediction and engineering division of the ground movement and deformation above the gob of a coal mine in Yulin

  • 摘要: 根据已有类似条件下的地表沉降监测资料,采用工程类比、典型曲线法、概率积分法及有限差分数值分析等多种手段和方法,对榆林某煤矿未来采空区地表移动变形规律进行预测。划定采动影响区为开采边界以外316m,最大下沉值为5760mm。结合建(构)筑物所能承受的允许变形值,将采动影响区根据工程需要划分为严重影响区、一般影响区和轻微影响区。为差别化利用土地资源、降低工程建设投资风险、充分利用煤炭资源提供科学依据。

     

    Abstract: Based on the monitoring data of ground subsidence under the similar circumstance, the future ground movement and deformation at a coal mining area inYulin is predicted by using engineering analogue method, curve analysis method, probability integration method and finite difference numerical analysis method.The mining-affected areas are designated as 316m outside the mining boundary, and the maximum ground subsidence is 5760mm.Combined with the deformation limits of the constructions, the mining-affected areas are divided into severe impacted section, relatively impacted section and slightly affected section according to project needs.It provides a scientific basis for differentially using the land resources, reducing the risks of investment in construction, and fully using the national coal and land resources.
