摘　　要：在煤炭资源枯竭矿井残煤、残气类型划分的基础上,提出了两种煤层气资源量估算方法,服务于我国报废矿井煤层气资源潜力初步评价及开发有利矿井筛选工作。资源可采性分类法基于"涌出下降曲线"与"物质平衡原理"分别对煤层气可采及不可采资源量进行估算,该方法涉及数据量少,适用于当前尚未关闭的煤炭资源枯竭矿井煤层气资源量估算。解吸过程法对具不同解吸特征的残煤分别计算其残气量,涉及参数的获取难度小,适用于当前已关闭的煤炭资源枯竭矿井煤层气资源量估算。On the basis of the division of residual coal and coalbed methane types in coal resources-exhausted mine,the authors propose two prediction methods of coalbed methane resources,which can service for the preliminary evaluation of coalbed methane resource potential and favorable coal mine screening in abandoned coal mines in China.Resources-mineable classification method can predict recoverable and non-recoverable coalbed methane resources based on ＂liberation decline curve＂ and ＂material balance principle＂ respectively.Resources-mineable classification method needs a few data,which applies to the coalbed methane resources estimation of unclosed coal resources-exhausted mine.Desorption process method calculates the residual gas volume of residual coal with different desorption characteristics.Desorption process method needs some easy-obtained parameters,which applies to the coalbed methane resources estimation of unclosed coal resources-exhausted mine.
