根据北洺河铁矿覆岩整体性差的特点,将基于地理信息系统(GIS)和概率积分法的MSDAS-GIS系统应用于采用无底柱分段崩落法的金属矿山的开采沉陷预计.通过GIS建模全面反映矿区的三维地理、地质信息及其内在属性,利用GIS的空间分析和图形显示功能对理论预计结果和现场监测结果进行综合分析,从而直观反映出开采沉陷对周围环境的影响程度及范围.
According to the poor integrity of Beitaihe iron ore overburden, MSDAS-GIS system based on GIS and probability integration method is applied to mining subsidence prediction of metal mines without bottom pillars Caving.By GIS The modeling comprehensively reflects the three-dimensional geography and geological information of the mining area and its intrinsic properties. The spatial analysis and graphic display function of GIS are used to comprehensively analyze the predicted results of the theory and the on-site monitoring results to intuitively reflect the impact of mining subsidence on the surrounding environment and range.
