摘　　要：通过利用热力学和流体力学理论推导出,在一定的温度、瓦斯压力与死空间体积等条件下,煤样罐内死空间涌出的初始释放瓦斯膨胀能的计算表达式;应用正交实验法进行一系列死空间初始释放瓦斯膨胀能实验,基于MATLAB软件建立一系列条件下的该实验数据库,据此验证一些实验测定的数值,经对比理论值和实验值,两者差距较小,很好的满足工程需要。Based on thermodynamics and fluid mechanics theory , under certain condition： Temperature, gas pressure and dead space volume and so on, the calculation expression of initial release of gas expansion energy which the dead space of coal tank emission is derived ; Used orthogonal experiment method, a series of the initial release of gas expansion testes which dead space gushed out had been done, based on MATLAB - software, a series of experiments database was established under a lot of conditions , Accordingly, some experimental verification of the value were determined , After the contrast theoretical value and the actual value, both the difference is smaller, which is very good to meet project needs.
