摘要
近年来,矿山地质灾害不断发生,给国家、矿山企业及广大人民群众造成了重大的经济损失和社会影响,严重制约了国民经济和社会的可持续发展。文章对引发矿山地质灾害的主要因素进行了分析,提出了矿山地质灾害危险性评估指标和评估指数,并结合目前地质灾害评估的主要特点和评估方法,构造了基于GIS技术的地质灾害信息系统模型(GHISM)用于矿山地质灾害评估,提高地质灾害评估和管理的科学性、准确性及有效性,进而提高减灾、抗灾的效率和水平。
In recent years, the continue occurrence of geological hazards of mine caused economical losses and have bad influence on our society. This paper has analysed the main factors of begetting geological hazards of mine and presents some indicators and indexes for evaluating the geological hazards of mine. Combining with the main evaluation characteristics and methods of geological hazards recently, a geological hazards information system model used in evaluating geological hazards on GIS technology, which can improve the veracity and of mine is constructed. This model constructed based validity of geological hazards evaluation and enhance the efficiency of resisting disaster.
