摘　　要：研究煤层气开采条件,首先要解决构造问题,而构造机理研究又是解决构造问题的核心。煤层具有天然裂隙系统,煤中的裂隙系统(割理)的形成、煤化作用与当地的构造特征密切相关,裂隙系统的好坏是开采煤层气的关键。本文研究恩洪盆地的构造和应力场特征、构造分区、优选区块,为煤层气的开发提供靶区,并为开发提供有力的技术支持和科学依据。In the study of exploitation conditions of seam gas, we have to solve the problem of structure first, moreover the core of the solution of tectonic problem is the study on tectonic mechanism. There is a natural fissure system in the coal. The formation of fissure system in the coal and the coalification are close related to the structural characteristics there. The key to the exploitation of seam gas is whether the fissure system is good or not. In this paper, we study the tectonic characteristics, stress field characteristics, tectonic area division and superiority block, and provide the target area, the strong technical support and scientific basement for the exploitation of seam gas.
