为了掌握回采工作面瓦斯涌出的状况及分布特征,寻找瓦斯的源头,确保工作面安全生产,通过对鸡西矿区某矿高瓦斯工作面的瓦斯来源及构成的研究分析,得出了回采工作面瓦斯涌出的分布规律。利用分源预测法对工作面瓦斯涌出量进行预测,依据工作面瓦斯涌出量构成及瓦斯涌出量预测结果,有针对性地提出了工作面瓦斯治理的几套措施,从而保证了该高产高效工作面的正常生产。
In order to grasp the status and distribution characteristics of gas emission in the working face, find the source of gas and ensure the safe production of the working face, through the research and analysis of gas sources and composition of the gas face in a mine in Jixi Mining Area, the working face Distribution of gas emission rules. Based on the prediction of gas emission from working face and prediction of gas emission, several measures of gas control at working face are put forward in order to ensure that the gas emission from working face is predicted. High production and efficient face of the normal production.
