摘要
在煤炭资源开发过程中,矿井突水灾害对安全生产构成很大威胁,而现有技术方法缺乏对突水灾害发生过程的时空表达。基于"三图法",分析并设计了煤层顶板突水三维动态可视化系统的实现方法。通过构建3D地质模型及"三图",以确定煤层开采模拟区域及突水点位置的各种候选方案,真实反映煤层开采过程中可能发生的实际复杂情况。在此基础上,经过地下水模拟、可视化预处理、刚体碰撞检测响应等,实现垮裂带及地下水流场的动态模拟分析。以内蒙古自治区中西部某矿为例,依据矿区数据,进行了煤层顶板突水动态可视化预测,为企业提供了一个了解和分析预测煤层顶板突水过程的崭新平台。
The water inrush disaster in coal mine poses a great threat to production safety in the development of coal resources. However, there is no temporal and spatial expression on the process of water inrush disaster. In this paper, a 3 D dynamic simulation was designed for water bursting on coal roof based on ＂three maps method＂. By constructing 3D geological models and ＂three maps＂ ,the designs from various options were determined as the simulated areas for coal mining and water bursting sources, in order to correctly reflect the actual situations that may occur during the coal mining process. Therefore, the dynamic simulation of fractured zone and groundwater flow field is achieved through groundwater modeling, visualization preprocessing, and collision detection and response based on rigid body. In a case study at a mine in the midwest of Inner Mongolia autonomous region, the dynamic visualization and prediction were ap- plied based on data from the mine. It provides a new platform for understanding, analyzing and forecasting the water bursting on coal roof.
