摘　　要：为对松散含水层下采煤进行安全分区,采用基于GIS的近松散含水层下煤层开采安全性评价方法,研究了某矿南六采区近松散含水层下采煤的主要影响因素,通过统计具有相似工程地质条件的矿区资料,用熵值法数学模型,确定各个因素的权重,运用GIS多元信息空间分析技术,对南六采区安全开采可行性进行分区,结果表明:在南六采区的安全可采区的Ⅰ区域布置的01工作面可以进行安全回采。实际回采过程中,该工作面顶板垮落正常,工作面顶板涌水量一般0～6m3/h,没有发生突水溃砂事件。In order to have the safety partition to the coal mining in a seam under unconsolidated aquifer, based on the GIS, the safety e- valuation method of the coal mining in the seam under the unconsolidated aquifer was applied to study the major influence factors of the coal mining under the unconsolidated aquifer in No. 6 South Mining Block of a coal mine. With the statistics on the mining block informa- tion with the similar engineering geological conditions, the mathematical method of the entropy method was applied to determine the weight of each factor. The GIS multi element information space analysis technology was applied to the partition of the feasibility for the safety min- ing of No. 6 South Mining Block. The results showed that No. 01 coal mining face in the safety mineable area of area I in No. 6 South Mining Block could have a safety mining. In the actual mining process, the roof of the coal mining face was normally fallen, the water in- rush from the roof of the coal mining face was 0 - 6 m3/h generally and there was no water inrush or quicksand accident occurred.
