Construction and application of gas resource estimation and evaluation method in abandoned coal mines

  • 摘要: 基于我国废弃煤矿瓦斯资源勘探开发现状,为合理评估我国废弃煤矿瓦斯资源,提出“资源估算+初步评价”的思路,建立废弃煤矿瓦斯资源估算和评价方法,该方法具有所需参数少和实用性强等优点;依据废弃煤矿瓦斯涌出特点及废弃时间,划分废弃煤矿类型,将其分为稳定型和非稳定型两大类,非稳定型进一步划分为初期、中期和后期3个阶段;根据废弃煤矿类型及瓦斯赋存特征,构建废弃煤矿瓦斯资源评价模型,将废弃煤矿瓦斯资源划分为16个类型,分析认为废弃煤矿中瓦斯资源主要以保有煤炭资源中赋存的瓦斯资源为主,动用煤炭遗煤中瓦斯资源及可解吸量相对较少;基于各类型的特点,从瓦斯资源和赋存角度,将其开发价值划分为相对较好、相对中等、相对较差和相对最差四级。最后以焦作矿区为例,统计主要煤矿关闭时间,划分废弃煤矿类型,重点评价2006年以来关闭的非稳定型废弃煤矿。估算焦作矿区近15年来,开采层废弃煤矿瓦斯资源量约为26.06×108 m3,其中,保有煤炭资源中瓦斯资源量约为20.75×108 m3,动用煤炭遗煤中瓦斯资源量约为5.31×108 m3,开发价值相对较好。
