摘　　要：本文介绍了铁法矿区概况,论述了铁法矿区井下瓦斯抽采、地面煤层气开发的主要技术方法;指出高瓦斯、低透气性、复合煤层群开采矿区,只要抓住瓦斯赋存规律、涌出特点,采用灵活多变的技术方法是可以实现高效瓦斯抽采与地面煤层气开发。This paper makes a general introduction of Tiefa mining area, and explains the rules of methane occurrence and its emission characteristics on the effects of mining activities. It also discusses the major technology for underground methane drainage and CBM surface development. The author points out that in the mining area with high gas content, low permeability, and multiple workable coal seams, only when we know better about the rules of methane occurrence and emission characteristics, can we adopt flexible technology so as to achieve effective methane drainage and CBM development.
