摘　　要：煤层煤与瓦斯突出危险区受断裂构造控制呈带状分布。贵州省地质地形条件复杂,矿区内断裂构造形态不规则,分布复杂,用传统的数学方法难以对其进行准确量化的描述。应用分形理论研究井田内断层构造对煤与瓦斯突出的控制作用,可以全面准确地量化表达断裂构造与瓦斯突出的关系。通过比较不同尺度上各类断裂构造对突出危险性的控制,可以形成较为可靠的突出预测指标。The seam of coal and gas outburst danger zone controlled by faults has a zonal distribution. The geo- logical and topographical conditions of Guizhou are complex. The faults in the mines are irregular. It is difficult to use traditional mathematical methods to accurately quantify its description. In this paper, the fractal theory is applied to describe fault structures within the coal and gas outburst in effect, which can fully and accurately quantify the relationship between faults and gas outburst. By comparing faults types of different scales on outburst control, a more reliable indicator for predicting gas outburst can be formulated.
