分析认为煤炭行业标准«矿井瓦斯涌出量预测方法»(AQ 1018－2006)中规定的矿山统计法瓦斯涌出量预测方法在多水平时计算瓦斯涌出量梯度的公式是错误的，且目前未见有相关的研究报道。针对这一问题，通过理论推导给出了正确的计算瓦斯涌出量梯度的公式，为矿山统计法预测瓦斯涌出量提供正确的理论依据。根据瓦斯涌出量梯度的含义，在EX-CEL表格中以开采深度为纵轴、相对瓦斯涌出量为横轴拟合出函数关系式求解，斜率的大小即是瓦斯涌出量梯度的值，此方法不仅简便，也提高了瓦斯涌出量梯度计算结果的准确性。%the equation of gas emission rate gradient in the multilevel calculation of the pre-dictions of gas emission quantity using mine statistical method,which was specified in the coal in-dustry standard"the mine gas emission quantity prediction method"(AQ 1018-2006 ),was an-alyzed and thought to be error,and relevant research was not reported at present. Aiming at this problem,the correction equation of gas emission rate gradient was provided by theoretical deriva-tion,which provided the right theory basis for predictions of gas emission quantity using mine statistical method. According to the meaning of gas emission rate gradient,the function equation with mining depth as vertical axis and relative gas emission quantity as horizontal axis in the EX-CEL worksheet was fitted and used for solution,the slope of equation is the value of the gas e-mission gradient. This method is simple and improves the accuracy of the gas emission gradient calculation.
