| 为保证磷矿地下开采的安全生产,防止水害事故的发生,对磷矿排水系统进行综合评价,建立了基于层次分析法(AHP)和熵权法的矿井排水系统评价模型。以贵州某磷矿为例首先分别从技术可行、安全可靠、经济合理三个方面选出11个评价指标,通过指数标度AHP计算指标因素的主观权重及熵权法确定指标客观因素,将两者线性组合计算综合权重,最后运用模糊集合理论对排水系统进行评价。根据计算该磷矿的指标权重结果可以得到；技术可行B1(0.3575)、经济合理B3(0.3352)、安全可靠B2(0.3073)；该磷矿排水系统评价的综合分数为6.25,隶属于较可靠的区间,此结果对该磷矿具有一定的参考意义。 |

| In order to ensure the safe production of underground mining of phosphate rock and prevent the occurrence of water disaster accidents, a comprehensive evaluation of the drainage system of phosphate rock was carried out, and an evaluation model of mine drainage system based on analytic hierarchy process ( AHP ) and entropy weight method was established. Taking a phosphate mine in Guizhou as an example, 11 evaluation indexes were selected from three aspects of technical feasibility, safety and reliability, and economic rationality. The subjective weight of the index factors was calculated by the index scale AHP and the objective factors of the index factors were determined by the entropy weight method, and the comprehensive weight was calculated by the linear combination of the two. Finally, the fuzzy set theory was used to evaluate the drainage system. According to the results of calculating the index weight of the phosphate rock, it can be obtained ; technically feasible B1 ( 0.3575 ), economically reasonable B3 ( 0.3352 ), safe and reliable B2 ( 0.3073 ) ; the comprehensive score of the drainage system evaluation of the phosphate rock is 6.25, which belongs to a more reliable interval. This result has certain reference significance for the phosphate rock. |
