摘　　要：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 geo-graphic 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 cal-culated 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 excava-tion arrangement, and adopt technical measures before coal mining, and avoid or reduce the stress concentration of mining which under the igneous rock.
