顺煤断层的基本类型及其对瓦斯突出带的控制作用

顺煤断层是指断面分为３种基本类型：褶皱型、带是瓦斯突出煤层或突出带，展布特征的研究，有助于构造与煤层呈小角度相交的断层，按其成因，顺煤断层被划型和转换型，在高瓦斯矿区，顺煤断层发育的煤层和地制构造煤的分布控制瓦斯突出带，顺煤断层形成机制和布的预测，进而实现瓦斯突出危险带预测。

BASIC TYPES OF COAL SEAM FAULTS AND THEIR EFFECT ON CONTROLLING GAS OUTBURST ZONE

Coal seam faults refer to those parallel to or intersected with seam at small angles. These faults fall into three categories according to their origin, namely, folding type, sliding type and transformation type. In highly gaseous mine coal seams and zones developed in coal seam faults are prone to gas outburst. To control gas outburst the method is to control the distribution of tectonic coal seams. Investigation of the forming mechanism and distribution features of coal seam faults will help to predict the tectonic coal distribution and to predict the proneness of gas outburst.
