高冒区由于遗煤自燃而成为内因火灾重要危险源之一。判定高冒区遗煤自燃的重要指标是释放的CO量。但是高冒区由于密闭严实,其内部遗煤自燃所释放的CO量人工测定比较困难,所以有必要选择一种模型对其进行预测。将采用灰色系统理论中的GM(1,1)模型,结合平煤十三矿11111巷道高冒区遗煤自燃氧化CO量变化值,说明建模过程。并将其应用于实际CO预测中,为煤矿做出正确决策提供科学依据。
As a result of spontaneous combustion of coal leftovers, high-risk areas have become one of the major hazards of internal fires. The key indicator for determining spontaneous combustion of coal in high-risk areas is the amount of CO released. However, because of the tight seal in the high-rise area, it is difficult to measure the amount of CO released by spontaneous combustion of internal coal, so it is necessary to select a model to predict it. The GM (1,1) model in gray system theory will be used in combination with the change of the value of spontaneous combustion CO in coal seam in 11111 coal mine roadway in Pingdingshan 13 Mine to illustrate the modeling process. And apply it to the actual CO prediction to provide a scientific basis for the coal mines to make correct decisions.
