基于不相容最小二乘理论的煤与瓦斯突出灾害的预测研究

Research on Prediction of Coal Layer Gas Outburst Disaster Based on Incompatible Least Square Theory

应用不相容方程组和最小二乘理论,根据已有的瓦斯压力原始统计资料,建立了煤层瓦斯压力和煤层地理位置关系的方程,并进行了相关性分析。分析结果表明可以根据此方程,由煤层所在的地理位置准确地预测煤层的瓦斯压力,进而对煤与瓦斯突出灾害进行预测,对矿山的生产和建设具有重要的实用价值。

The theory of incompatible equations and least square are used to build an equation about the pressure of gas and the site of coal, according to the original statistical data of gas pressure . Analysis on the pertinence between the gas pressure and the site of coal is also given. The result of the analysis indicates the gas pressure can be acquired exactly by the site of the coal and the equation. So the disaster of coal and gas outburst can be predicted further. It has significant and practical value for the production and construction of mine.
