    摘要:

    煤与瓦斯协同共采是煤矿绿色开采主要发展方向。目前,尚未构建全面、科学的煤与瓦斯共采评价指标体系;另外,由于指标的未知性、不确定性,难以确定合理的指标权重,缺少准确的煤与瓦斯共采评价模型和方法。对此,构建了以地质赋存条件、经济成本条件、技术水平条件、安全管理条件4个因素为准则层,煤层及瓦斯赋存条件、煤层透气性、煤层稳定性等24个因素为指标层的煤与瓦斯共采评价体系;提出了一种基于博弈论组合赋权的方法,将熵权法获得的客观权重与层次分析法获得的主观权重有效融合,获得合理的指标权重,通过组合权重可知,指标对煤与瓦斯共采的影响由大到小为:煤层及瓦斯赋存条件>煤层透气性>卸压增透情况>共采设备情况>煤层稳定性>地质构造复杂程度;将组合权重与逼近理想解排序法相结合,构建了CW-TOPSIS煤与瓦斯共采评价模型。运用CW-TOPSIS模型对某煤矿煤与瓦斯共采可行性进行评价,结果为“良”等级;将该模型与贝叶斯模型、模糊综合评价法、基于云模型和D-S理论的评价模型进行分析讨论,研究表明:CW-TOPSIS模型不仅可以准确反映评价等级,还可以反应评价结果的偏好程度,准确度更高,该模型具有较高的应用价值。

    Abstract:

    The coordinated co-mining of coal and gas is the main development direction of green mining in coal mine. At present, a comprehensive and scientific evaluation index system of coal and gas co-mining has not been constructed; in addition, due to the unknown and uncertainty of the index, it is difficult to determine the reasonable index weight, and there is a lack of accurate coal and gas co-mining evaluation model and method. In view of this, the evaluation system of co-mining of coal and gas is constructed based on four factors: geological occurrence conditions, economic cost conditions, technical level conditions and safety management conditions. Coal seam and gas occurrence conditions, coal seam permeability, coal seam stability and other 24 factors as index layer. In this paper, a combination weighting method based on game theory is proposed, which effectively combines the objective weight obtained by entropy weight with the subjective weight obtained by Analytic hierarchy process to obtain reasonable index weight. the influence of index on coal and gas co-mining is as follows: coal seam and gas occurrence condition > coal seam gas permeability > pressure relief and permeability increasing condition > co-mining equipment > coal seam stability > geological structure complexity. Combining the combination weight with the approximate ideal solution ranking method, the evaluation model of CW-TOPSIS co-mining of coal and gas is constructed. The feasibility of co-mining of coal and gas in a coal mine is evaluated by using CW-TOPSIS model, and the result is "good" grade. The model is analyzed and discussed with Bayesian model, fuzzy comprehensive evaluation method, evaluation model based on cloud model and Dmurs theory. The research shows that CW-TOPSIS model can not only accurately reflect the evaluation grade, but also reflect the preference degree of evaluation results, with higher accuracy, and the model has higher application value.
