基于AHP-FCE对薄煤层采煤工作面长度优化的研究

Research on Length Optimization of Coal Mining Face in Thin Coal Seam Based on AHP-FCE

薄煤层是今后我国煤矿开采的重要方向之一,而合理的工作面长度是提高煤炭回收率,减少资源损失,达到高效开采的关键。通过层次分析法(AHP)建立了影响薄煤层工作面长度因素的层次模型,并得出判断矩阵,再根据模糊综合评判(FCE)结合大同地区某矿井实际情况,找出适合该矿薄煤层矿井工作面的合理长度范围,从而为矿井高效生产提供理论基础。

Thin coal seam is one important direction of coal mining of our country in the future, while reasonable working face length is the key to increase coal recovery, reduce resource loss and achieve high efficiency mining. Based on analytic hierarchy process(AHP), a hierarchical model of the factors affecting the length of thin coal seam faces is established, and the judgment matrix is obtained. Then, according to the fuzzy comprehensive evaluation(FCE), combined with the actual situation of a mine in Datong area, we find out the reasonable length range of mine face which is suitable for thin coal seam in this mine, thus provide the theoretical foundation for the high efficiency production of mine.
