基于量纲理论的煤层瓦斯压力计算模型的优化

煤层瓦斯压力预测对煤与瓦斯突出和煤层安全开采意义重大。在陈连省等基于量纲分析建立的煤层瓦斯压力计算模型的基础上,通过重新进行量纲分析以及MATLAB数值模拟分析,利用已有的实测数据,针对其所建立的煤层瓦斯压力计算模型进行了重新建模和优化,新模型为整体的一个数学模型,避免了原分段数学模型带来的误差,使得煤层瓦斯压力的预测计算更为准确,可为煤层瓦斯压力的预测提供参考。

Optimization of the Calculation Model of Coal Seam Gas Pressure Based on the Dimensional Theory

It has great significance to predict the coal seam gas pressure for the coal and gas outburst and safety mining of coalbed.On the basis of the coal seam gas pressure calculation model by dimensional anal-ysis by Chen Liansheng et al.,through the dimensional analysis and MATLAB numerical simulation analy-sis,this paper rebuilds and optimizes the model by using the existing measured data.The new model is a continuous mathematical model which avoids the error of piecewise mathematical model and makes the forecast of coal seam gas pressure more accurate.The model provides reference for the forecast of coal seam gas pressure.
