摘要
为进行王庄煤矿下组煤煤层底板突水评价,引用了基于GIS的脆弱性指数法。即首先分析煤层底板突水主控因素,并通过GIS对主控因素数据进行采集及归一化处理,建立子专题图层,然后运用AHP法确定各主控因素的权重比例,在此基础上,提出煤层底板突水脆弱性的分区方案。将新的脆弱性指数法与传统的突水系数法的评价结果进行详细对比和分析,证明脆弱性指数法在煤层底板突水脆弱性评价的许多方面具有明显优势,能够妥善解决安全生产实践中遇到的突水评价问题。
For evaluate lower coal seam floor water burst in Wangzhuang Coal Mine,we cited vulnerability index method based on GIS.That is,firstly analyzes the water burst master factors,and through GIS to control factors of data acquisition and normalized processing,establish the son project layer,then using AHP to determine the weight of each main controlling factors of the proportion,and proposed the water burst vulnerability zoning scheme on this base.Through detailcomparision and analysis of new vulnerability index method and traditional water burst,the article proves that vulnerability index method in the water burst vulnerability has many obcious advantages,which can properly solve the safety production practice in the water burst evaluation.
