基于多源数据融合的矿井水害“一张图”预警平台构建与应用

Construction and Application of"One Map"Early Warning Platform for Mine Water Disaster Based on Multi Source Data Fusion

现阶段矿井水害预警工作以水文地质参数、应力、应变等指标的阈值上下限监测为主,监测到的信息难以体现工作面开采过程中复杂的突水机理。为解决亭南矿在开采过程中顶板及老空水突水的监测预警问题,以“上三带”理论为基础,采用单因子监测指标梳理、多源数据融合预警方法,基于Spring Boot框架和GIS技术构建并设计了矿井水害“一张图”预警平台。结果表明:①该矿水害预警指标选取应集中在矿井水情、水文信息、微震导水通道监测及涌水量预测方面;②平台具备矿井水情风险五大数据库以及基础信息管理、数据信息管理和多源数据融合预警三大主要功能;③将导水裂隙带高度、进尺点与采空区距离、水压变幅3个指标的监测数据划分成4个预警等级,有效满足了矿井水害防治的实际需要。该平台的建立有助于矿井水害“一张图”管理模式的形成。

At present,the early warning work of mine water disaster mainly focuses on the upper and lower threshold monitoring of hydrogeological parameters,stress,strain and other indicators,and the monitored information is difficult to reflect the complex water inrush mechanism in the mining process of working face.In order to solve the problem of monitoring and early warning of water inrush from roof and goaf in the process of mining in Tingnan Mine,based on the theory of"upper three zones",using the method of single factor monitoring index combing and multi-source data fusion early warning,the"one map"early warning platform of mine water disaster is constructed and designed based on spring boot framework and GIS technology.The results show that:①the selection of early warning index of mine water disaster should focus on mine water regime,hydrological information,microseismic water channel monitoring and water inflow prediction;②The platform has five major database of mine water regime risk and three main functions of basic information management,data information management and multisource data fusion early warning;③The monitoring data of the three indicators of the height of water flowing fracture zone,distance between footage point and goaf and water pressure are divided into four early warning levels,which realizes the actual needs of mine water disaster prevention and control.The establishment of the platform is helpful to the formation of"one map"management mode of mine water disaster.
