摘要
在本煤层抽放瓦斯工程中,有效半径和钻孔间距是合理布置抽放钻孔的两个主要参数.作者根据煤层瓦斯动力学的理论模型,推导出合理布置钻孔的两个主要参数之解析式.
The effective radius and rational distances between bores of drainage gas in coal seams are two of the fundamental parameters of the rational arrangement bores in the engineering of drainage gas. Based on the theoretical model of coal gas dynamies, the mathematical expressions of the rational arrangement bore parameters of drainage gas in coal seams have been deduced by the author.
