脆弱性指数法在煤矿底板突水评价中的应用

Application of Vulnerability Index Method in Coal Floor Water Bursting Evaluation

应用脆弱性指数法对研究区进行煤层底板突水脆弱性评价预测,确定各主控因素的相对影响权重,建立突水脆弱性评价模型。根据模型计算各区突水脆弱性指数,利用自然分级法对脆弱性指数进行分析研究,确定底板突水脆弱性分区阈值,提出煤层底板突水脆弱性区划方案,最终得出煤层底板突水脆弱性评价分区图。

Coal floor water bursting evaluate by vulnerability index method, determining the relative weight of each main control factors of influence, establishment of coal floor water bursting vulnerability evaluation model, according to model, calculate water bursting vulnerability index, studying it by natural grading, determination of the water inrush vulnerability threshold, proposed its vulnerability zoning scheme, the final draw water inrush vulnerability zoning map evaluation.
