研究了数量化理论Ⅰ建模的原理和方法,收集了近3年来100多对矿井的实测初始释放瓦斯膨胀能资料,获得10组可靠数据,选取煤的破坏类型为定性说明变量,瓦斯放散初速度、煤的坚固性系数、瓦斯压力为定量说明变量,建立了基于数量化理论Ⅰ的初始释放瓦斯膨胀能预测模型,通过模型检验和精度分析,得出模型拟合效果好,预测精度能够满足工程精度要求,说明利用数量化理论对初始释放瓦斯膨胀能进行预测是可行的。
The principle and method of quantitative theory Ⅰ modeling are studied. The measured data of initial released gas expansion energy of more than 100 pairs of mines collected during the past 3 years, 10 sets of reliable data are obtained, the types of coal destruction are selected as qualitative explanatory variables, Speed, solidity coefficient of coal and gas pressure as quantitative explanatory variable, the initial release gas expansion energy prediction model based on quantitative theory Ⅰ is established. The model test and accuracy analysis show that the model fitting effect is good and the prediction accuracy can meet The requirement of engineering accuracy shows that it is feasible to predict the initial released gas expansion energy by using the quantitative theory.
