由于南阳坡煤矿3~#、5~#、8~#煤层在开采过程中受到奥灰水的严重威胁,为了排除突水隐患,运用GIS的AHP型脆弱性指数法,结合该矿实际生产地质条件,选择影响各煤层突水的主要因素为评价指标,运用AHP法计算各评价指标的影响权重,建立单因素评价图件,最后对单因素图件进行叠加处理,成功实现了对煤层底板不同脆弱程度区域的评价。
Because Nangyangpo Coal Mine 3 ~ #, 5 ~ #, 8 ~ # seam is seriously threatened by Ordovician gray water in the process of mining, in order to eliminate water inrush hazard, AHP Vulnerability Index Method of GIS is used in combination with actual production geology of this mine Conditions, select the main factors that affect the water inrush of each coal seam as evaluation index, use AHP method to calculate the influence weight of each evaluation index, establish the single factor evaluation map, and finally superpose the single factor map, successfully achieve the coal seam floor different Evaluation of vulnerability areas.
