摘要
为优选首采层作为保护层开采,选取5个一级指标和19个二级指标,建立以AHP(层次分析法)和TOPSIS(逼近理想解排序法)为基础的煤层突出危险性评价模型,通过层次分析法确定各指标的权重,结合逼近理想解排序法分析贴近度并预测出煤层突出危险可能性,并进行现场工业性实验。结果表明:AHP-TOPSIS综合评判法预测优选8号煤层作为保护层开采,并经现场工业性实验验证,瓦斯解放效果较好。该方法结合主观因素和客观因素,避免单一地从主观出发或从客观出发带来的决策失误,并选取大量评价指标,使预测结果更贴合实际情况,可作为优选保护层的理论依据。
In order to optimally select the first mining layer as the protective layer mining,5 primary indexes and 19 secondary indexes were selected to establish an evaluation model of coal seam outburst risk based on AHP(analytic hierarchy process)and TOPSIS(technique for order preference by similarity to an ideal solution).The weight of each index was determined by AHP,and the closeness was analyzed by TOPSIS to predict the possibility of coal seam outburst risk,then the on-site industrial tests were conducted.The results showed that the AHP-TOPSIS comprehensive evaluation method predicted that the No.8 coal seam should be optimally selected as the protective layer mining,and the gas liberation effect was better through the verification of on-site industrial tests.This method combined the subjective and objective factors,avoided the decision-making error caused by a single subjective or objective starting point,and selected a large number of evaluation indexes to make the prediction results more suitable for actual conditions,more scientific,and more accurate,so it could be taken as the theoretical basis for the preferred protective layer.
