瓦斯涌出量预测及工作面通风系统的研究分析

Prediction of Gas Emission and Study and Analysis of Ventilation System in Working Face

针对煤炭开采过程中瓦斯涌出作为引发瓦斯灾害的最关键原因,以山西高平科兴云泉煤业有限公司9103综采工作面为研究背景,分析研究了瓦斯涌出量的影响因素以及预测指标。采用分源预测法对9103工作面瓦斯涌出量进行预测,同时根据预测结果确定9103工作面通风需风量和风流路线。为后续其他工作面瓦斯涌出的防治研究奠定了基础。

In view of the gas emission in the coal mining process as the most critical cause of gas disasters, the 9103 fully mechanized mining face of Shanxi Gaoping Kexing Yunquan Coal Industry Co., Ltd. was used as the research background to analyze the influencing factors and predictive indicators of gas emission. The gas emission from 9103 working face is predicted by using the method of separate source prediction. At the same time, the ventilation demand and air flow route of 9103 working face are determined according to the prediction results. It lays a foundation for the follow-up study of gas emission control in other working faces.
