上隅角瓦斯浓度动态预测模型的研究及应用

Research and application on dynamic forecasting model of gas consistence in top corner

通过对采煤工作面上隅角瓦斯浓度影响因素的研究,认为上隅角瓦斯浓度的变化受诸多因素的影响和制约,因素与因素之间的作用关系很难确定,无法用解析函数来描述其变化规律.因此,应用灰色系统控制理论建立了相应的动态预测分析模型,该模型在实际应用过程中能较好地反映采煤工作面上隅角瓦斯的变化规律.

The influence factors in the excavate coal face top corner corner＇ s gas consistence were analyzed, and authors consider that the change of top corner gas consistence is affected and restricted by many factors, it is difficult to describe its variety rule. The control system of the top corner gas is full of gray phenomenal gray system, and the corresponding dynamic forecasting and analyzing model was built by appling gray control theory. The model can preferable reflect the variable rules of the top corner gas in the practice.
