煤与瓦斯共采评价指标体系及评价模型的应用

针对我国尚未形成系统性的煤与瓦斯共采基础理论体系的现状，提出经济预评价、安全评价、共采效果3部分建立煤与瓦斯共采评价系统，并建立多层次评价指标体系，构建煤与瓦斯共采模糊综合评判模型。将模糊层次法（FAHP）与层次分析法（AHP）组合赋权，将专家的主观经验与目标区指标客观反映相结合，建立模糊综合评判模型对沙曲矿煤与瓦斯共采进行综合评价。在共采系统各部分的模糊综合评价的基础上，利用协调度函数量化煤炭开采与瓦斯抽采系统之间的协同程度。评价结果表明，沙曲矿24207工作面煤炭开采子系统和瓦斯抽采子系统初级协调有序，煤与瓦斯共采技术是合理可行的。

Application of evaluation index system of coal and gas co-extraction and evaluation model

Currently a systematical basic theory for coal and gas co-extraction in China has not been formed.A coal and gas co-extraction system was developed in this study based on three stages including economic evaluation,effect of extraction,and multi-level index system.The fuzzy comprehensive evaluation model was used to conduct the evaluation of coal and gas co-extraction.The Fuzzy Analytic Hierarchy Process (FAHP) and Analytic Hierarchy Process (AHP) were weighted and combined,also,the experts’ subjective experience and the objective reflection indicator of target zone were combined,thus,the fuzzy comprehensive evaluation model was established.A comprehensive assessment of coal and gas co-extraction is conducted in Shaqu Coal Mine.The cooperation level between coal mining and gas extraction system was quantified by using coordination function based on the fuzzy comprehensive evaluation of each part of the extraction system.The evaluation results show that the subsystem of coal mining and gas extraction in 24207 working face at Shaqu Coal Mine is orderly coordinated;the technology of coal and gas co-extraction in Shaqu Coal Mine is reasonably practicable.
