摘要:利用常村井田 2 1采区一分层回采时实测的绝对瓦斯涌出量数据和采区内 1 2个钻孔的原始数据 ,用多元线性回归分析法 ,找出了控制瓦斯涌出量的主要地质因素是煤层厚度和煤层埋深 .根据回归方程 ,计算出矿井瓦斯梯度为每百米增加 0 .67m3/min ,并对矿井深部一分层开采时的瓦斯涌出量进行了预测 .以 5m3/min绝对瓦斯涌出量等值线为界 ,把整个井田划分为低瓦斯区和中高瓦斯区 ,指出在矿井深部煤层开采时 ,必须提前制定出防止瓦斯事故发生的有效措施

The prediction of gas emission in deep area of mine field bymultivariate linear regression analysis

Abstract:On the basis of the original data of 12 drill holes and measured data of gas emission from the lst slice in Mining Area 21 of Changcun mine field, it has stated that the main geological factors of gas emission are thickiness and depth of coal seam.According to linear regression equation, it is calculated that the gas gradient is 0.67m 3/min, and the quatity of gas emission is predicted before mining 1st slice in deep area.The mine field is devided into low gas area and high one by boundary of gas emission isoline 5*!m 3/min.It has pointed out that preventive measures of gas accident must be taken before mining deep area.
