多源信息复合技术在矿井水害预防中的应用

Application of Multisource Information Composite Technology to the Prevention of Coal Mine Flood

以赵官井田首采面13煤层底板奥灰为研究对象,运用GIS和多源信息复合技术对其进行了突水灾害预测预报研究:即以GIS的基本功能为工具,在系统分析底板突水机理基础上,提出控制13煤层底板奥灰突水的主要因素;将已知的每个因素编制一张专题信息图,并生成一个信息存储层,经编辑后,先做单因素分析;然后进行各主要控制因素的信息配准复合处理.形成一个复合叠加的新的信息存储层;最后构建底板突水灾害GIS数学模型,确定煤层底板突水灾害模式,对奥灰进行突水危险程度分区,从而为奥灰突水灾害的预测预报提供依据,对矿井的安全生产具有重要的指导作用和现实意义。

Using GIS and multisource information composite technology, this paper conducts the research of the water bursting prediction and forecast. The Ordovician limestone located at the 13th coal seam floor of Zhaoguan underground coal mine is the object of this research. Taking GIS basic functions as tools and based on systematically analyzing the water bursting mechanism, the main factors controlling the Ordovician limestone water bursting at the 13th coal seam floor are suggested. Each known factor is compiled into a thematic information diagram and a corresponding information storage is generated at the same time. After compilation, the single factor analysis is first made. Then the information of each main controlling factor is processed compositely and a new composite information storage is formed. Finally, the GIS mathematical model of the coal seam floor water bursting is constructed, the pattern of the coal seam floor water bursting is determined, and the Ordovician limestone is zoned according to the risk degree of water bursting. In this way, we can provide technical support to the prediction and forecast of the Ordovician limestone water bursting and make important contribution to the safety in the underground coal mine production.
