南阳坡矿石炭系煤层底板突水脆弱性评价

Vulnerability Assessement of Coal Floor Water Bursting of Nanyangpo Coalmine′s Carboniferous Coal Seam

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。

A. main controlling factor system of coal floor water bursting has established to address the Nanyangpo coalmine＇s No. 3^#,5^#,8^# coal seam, the application of AHP vulnerable index method based on GIS, then put to use of AHP to determine weighted percentage of each main controlling factor according to the actual geological conditions of the coal mine , and produe thematic maps. Using the principle of superposition,coal floor water bursting vulnerability zoning scheme put forward, prediction of coal floor water bursting in cutting face successfully.
