【摘要】：AHP法是煤层底板突水预测预报的关键技术之一,但传统基于"1~9"标度的AHP法往往存在一致性效果不够理想等问题.通过对AHP法的改进研究,提出了基于"10/10~18/2"标度的改进AHP法型脆弱性指数法评价技术.以成庄矿3~#、9~#和15~#煤层底板奥灰突水脆弱性评价为例,在建立各主控因素专题层图基础上,应用基于"10/10~18/2"新标度的改进AHP法,确定了各主控因素的权重;进一步建立了煤层底板奥灰突水的脆弱性评价模型,得出了各煤层脆弱性评价分区.研究表明,改进的AHP法构建的判断矩阵具有较好的一致性;通过与传统突水系数法评价结果对比可知,基于GIS的改进AHP型脆弱性指数法评价能够真实反映多因素影响下煤层底板突水的非线性动力过程,评价结果更为吻合实际.
[Abstract]:AHP method is one of the key techniques for prediction and prediction of water inrush from coal seam floor. However, the traditional AHP method based on "1 / 9" scale often has some problems such as poor consistency effect and so on. Through the research on the improvement of AHP method, an improved AHP vulnerability index evaluation technique based on the scale of "10 / 10 / 18 / 2" is proposed. Taking the vulnerability evaluation of Ordovician ash inrush from coal floor of No. 3, #y9 # and 15 # coal seam in Chengzhuang Mine as an example, the weight of each main controlling factor is determined by using the improved AHP method based on the new scale of "10 / 1018 / 2" and on the basis of establishing the thematic layer map of the main control factors. The vulnerability assessment model of Ordovician ash water inrush from coal seam floor is further established, and the zone of vulnerability assessment of coal seam is obtained. The results show that the judgement matrix constructed by the improved AHP method is consistent with the traditional water inrush coefficient method. The improved AHP vulnerability index method based on GIS can truly reflect the nonlinear dynamic process of water inrush from coal seam floor under the influence of multiple factors, and the evaluation results are more consistent with the actual situation.
