【摘要】：我国煤矿每年都会发生很多矿井水灾事故,给国家和企业带来巨大的经济财产损失。矿井水灾作为煤矿安全的五大灾害之一,指矿井水从突水点涌出,沿着巷道淹没井下空间的过程。随着数字矿山在煤矿企业中的大力推广,矿山信息化水平得到了显著提升,通过对灾害进行预测预报,使矿山安全性能得以提高。矿井水淹模型,是地理信息系统在矿山水文的典型应用。是以矿井地图为载体,获取某特定条件下矿井突水淹没情况,实现在矿井空间中的模拟。矿井水淹模型,为矿井水淹过程的预测模拟,提供了理论依据,也为科学高效地指导矿井水灾救援,提供了技术支持。将在矿井水灾的预测模拟中,发挥重要的作用,不断服务于煤矿企业的安全生产。本文基于VRMine开发平台,在矿井制图的基础上,建立起巷道的空间网络关系,以网络关系为基础,根据水流特征,设计并开发出矿井水淹模型算法。实现由突水点、淹没水位或水量等监测数据,获得井下被淹没的巷道信息,模拟矿井淹没的变化过程。进而可实现淹没统计分析,淹没预测分析,避淹路径分析等功能。该模型以水淹算法逻辑、淹没体积计算为支撑。文章核心介绍了巷道网络构建算法、水淹模型算法、水淹避灾路径算法等内容,希望从矿井水淹模拟与预测方面,为矿井安全提供服务。
[Abstract]:Many mine flood accidents occur every year in our country's coal mines, which bring huge economic and property losses to the country and enterprises. As one of the five major disasters of coal mine safety, mine flood refers to the mine water gushing out from the water inrush point. Along the course of submergence of underground space in roadway, with the popularization of digital mine in coal mine enterprise, the level of mine informatization has been greatly improved, and the disaster prediction has been carried out. Mine water flooding model is a typical application of GIS in mine hydrology. The model of mine flooding provides a theoretical basis for the prediction and simulation of the process of mine flooding, and also provides technical support for the scientific and efficient guidance of mine flood rescue, which will be used in the prediction and simulation of mine flooding. This paper, based on VRMine development platform and on the basis of mine drawing, establishes the spatial network relationship of roadway, which is based on the network relationship and the characteristics of water flow. The algorithm of mine flooding model is designed and developed. The monitoring data such as water inrush point, submerged water level or water quantity are realized, and the information of underground submerged roadway is obtained, and the changing process of mine submergence is simulated, and the statistical analysis of submergence can be realized. The model is based on the logic of waterflooding algorithm and the calculation of submergence volume. This paper introduces the construction algorithm of roadway network, the algorithm of waterflooding model, the algorithm of waterflooding avoidance path and so on. The author hopes to provide service for mine safety from simulation and prediction of mine flooding.
