中文摘要：

梁北二井具有较为丰富的煤层气资源。文章根据煤田勘探、煤层气勘探与实测数据为资料，对梁北二井煤层气赋存特征进行系统论述。指出该区煤的吸附能力强，煤层气含量为0～20m^3／t，总体具有南高北低、西高东低的展布规律。这种展布规律主要受其埋深和地下水动力条件的影响，井田南部埋深较深且地下水滞留区成为煤层气富集的有利场所。梁北二井的地质条件决定了其中南部煤层气的富集，但强烈的构造运动使得煤体破坏为糜棱煤，渗透性差，致使该区煤层气开发仍是个值得探讨的问题。

英文摘要：

Liangbei No. 2 mine has fairly rich coalbed methane resources. The paper makes a systematic description of CBM occurrence characteristics in Lianghei No. 2 mine based on measured data obtained from coalfield exploration and CBM prospection and the measured data. Coal in the mining area has strong adsorption capacity, and the gas content varies from 0 - 20m^3/t. The general spreading rule of the landform is high in the south and low in the north and high in the west and low in the east, which is mainly influenced by the burial depth and dynamic conditions of the ground water. In the southwest part of the mine field the burial depth is deep, and the ground water retention zone has become a favorable place for enrichment of CBM. The geological conditions of Liangbei No.2 mine determine enrichment of CBM in the south part. However, the intensive tectonic movement has damaged the coal mass into mylonitic structure coal with poor permeability. Thus, the development of CBM in this area is an issue worthy of discussion.
