淮南矿区谢一矿煤与瓦斯突出分布规律

摘要

In order to research the influence of geological structure factors in Xieyi mine of Huainan mining area on the coal and gas outburst, and then analyze the regional distribution rule of coal and gas outburst, this paper concluded that the coal and gas outburst point of Xieyi coal mine has the characteristics of regional distribution through the investigation of the landform, the study of geological structure, and the monitoring of gas emission in the mining area, and the outburst point distributed in the geological structure control area. The index of coal and gas outburst is the smallest gas pressure of 1.59MPa, and it is divided according to the different region of coal and gas outburst, which provided guidance to the research of the distribution rule of coal and gas outburst and the basis for the prediction and prevention of coal and gas outburst in the mining area.%为了研究淮南矿区谢一矿地质构造因素对井田内煤与瓦斯突出的影响，进而分析煤与瓦斯突出发生的区域性分布规律。本文通过对矿区地形地貌的考察，地质构造研究，瓦斯涌出量的监测，得出谢一矿煤与瓦斯突出点具有区域性分布的特点，而突出点集中的分布在地质构造控制区域内；煤层煤与瓦斯突出的指标是最小瓦斯压力为1.59MPa，以对井田内煤与瓦斯突出不同区域进行划分。为研究矿区内煤与瓦斯突出的分布规律提供了指导，为矿区开采过程中煤与瓦斯突出的预测和防治提供了依据。
