基于B/S架构的抚顺西露天矿WebGIS系统构建

Establishment of WebGIS system of Fushun West Open-pit Mine Based on B/S Framework

抚顺西露天矿现已接近闭坑阶段,南北两帮高陡边坡的防治是目前亟待解决的难题。矿山往往聚焦二维GIS地图,建模技术精度较低、数据来源单一、平台束缚性较高,很难实时、高效以及流程化地与三维空间数据相结合进行空间分析。为此,基于B/S架构,对SuperMapWeb端进行了二次开发,构建了抚顺西露天矿WebGIS系统。该系统以"地下—地表—地上"多空间真三维精细化建模为基础,将三维GIS空间计算能力应用到高精度数字高程模型DEM中,高效解决了不同治理方案的施工周期及回填方量预测计算问题。根据该系统的体积分析模块,对抚顺西露天矿提出的治理方案的回填方量、充水量、削坡量及回填周期进行了计算,得出回填方量为1.78亿m^(3),充水量为6.9亿m^(3),削坡量0.23亿m^(3),回填治理周期为10.5 a。同时将矿山地质资料、滑坡区、力学计算、水文地质信息以及InSAR监测数据等信息进行融合,创建了多维度的多元信息集成化平台,有效解决了信息孤岛问题。

Fushun West Open-pit Mine is close to the stage of pit closure,and the treatment of high and steep slopes in the north and south sides is an urgent problem to be solved.Traditional mines often focus on two-dimensional GIS map,the shortcomings of low accuracy of modeling technology,single the data source,higher restrains of platform was existed,besides that,it is difficult to combine real-time,efficient and process-oriented three-dimensional spatial data for spatial analysis.Based on the B/S framework,the secondary development of SuperMap web end was done,and the WebGIS system of Fushun West Open-pit Mine was established.Based on"underground-surface-ground"multi-space true 3D fine modeling,the 3D GIS spatial computing ability was applied to the high-precision digital elevation model(DEM),so as to effectively solve the prediction calculation problems of the construction period and backfill volume of different treatment schemes.According to the volume analysis module of the system,the backfill volume,water filling volume,slope cutting volume and backfill period of the treatment scheme proposed by Fushun West Open-pit Mine were calculated.The results showed that the backfill volume is 178 million m^(3),the water filling volume is 690 million m^(3),the slope cutting volume is 23 million m^(3),and the backfill treatment period is 10.5 years.At the same time,based on the integration of the information of mine geological data,landslide area,mechanical calculation results,hydrogeological information and InSAR monitoring data,a multi-dimensional multivariate information integration platform was established,the problem of information island was effectively solved.
