矿井高地应力区的合理划分对煤矿组织生产、防止煤与瓦斯突出等事故至关重要,采用大型地理信息系统ArcGIS,建立了矿井三维地质模型,实现了矿井各关键岩层的三维信息可视化和直观化.通过大型三维数值模拟,计算并划分了已采采区周边高地应力区域,并将应力云图与三维数字模型合成,分析得出的海孜煤矿巨厚火成岩下采煤矿井采动应力分布规律,可为矿井在采场布置、采掘安排,以及煤层开采前采取技术措施提供参考,避免或减轻火成岩下采煤所产生的采动应力集中.%For it is very important to organizing production and preventing coal and gas outburst in coal mine,by using large-scale geographic information system ArcGIS,3D geological model of the coal mine was established,and 3D information visualization of every key strata was realized.Through large-scale 3D numerical simulation,the high field stress in mining area which has been recovered were calculated and divided.The stress nephogram and 3D digital model were synthesised,and the stress distribution of dynamic mining which under the mega-thickness igneous rock in Haizi Coal Mine was analyzed.These can provide reference for stope layout,mining or excavation arrangement,and adopt technical measures before coal mining,and avoid or reduce the stress concentration of mining which under the igneous rock.
