煤层顶板稳定性问题是煤矿安全、高效生产的重要前提。择优分析影响煤层顶板稳定性的因素,建立了因素集和评价集。引进了模糊数学理论,建立了综合评价煤层顶板稳定性的模型,输出决策结果。得到煤层顶板稳定性位于Ⅱ级较稳定等级,给出了煤层顶板稳定性预测图,为煤矿的开采设计提供了重要的依据。
The roof stability of coal seam is an important prerequisite for safe and efficient coal production. Based on the analysis of the factors affecting the roof stability of coal seam, the set of factors and the evaluation set are established. The introduction of fuzzy mathematics theory, the establishment of a comprehensive evaluation of coal seam roof stability model, the output decision-making results. The stability of the roof of the coal seam is obtained at a relatively stable grade of level II, and the prediction diagram of the roof stability of the coal seam is given, which provides an important basis for the mining design of the coal mine.
