摘要
构造煤是煤矿瓦斯灾害防治和煤层气开发的重要研究内容之一。依据断层成因理论,对逆断层的形成进行动力学和运动学分析,从时间上和空间上论述了断层两盘的应力分布和构造煤的分布特点。研究表明,断层上盘为主动盘,下盘为被动盘,构造煤具有片状序列结构特点,而且主要形成在断层上盘一定宽度的范围内,构造煤的厚度和发育程度随着远离断层而减小。
Structural coal is one of important study contents for the prevention and control of gas disasters and the exploitation of coal-seam gas,this paper made dynamical and kinematical analysis on the formation of reverse faults according to the genesis theory of coal,and discussed the stress distribution on two sides of fault and the distribution characteristic of structural coal from time and space.Study showed that the hanging side was the active one and the lying side was the positive one,the structural coal was featured by sheet serial structure and was mainly formed in a range with certain width of the hanging side of the fault,and its thickness and development degree decreased with increase of distant to the fault.
