近距离煤层开采瓦斯涌出量预测及其影响因素分析

 瓦斯涌出量预测是矿井初步设计中的一个重要因素，对做好矿井的瓦斯管理及相应的通风、抽放等工作有着重要作用。本文采用分源预测法对近距离煤层开采时的矿井瓦斯涌出量进行预测，在煤层瓦斯地质覆存条件相似的情况下，近距离煤层瓦斯涌出量预测结果相差较大。研究发现邻近层瓦斯排放率是影响近距离煤层瓦斯涌出量预测结果相差较大的最主要因素。

The prediction of amount from the gas emission in coal mining for short distance seam and the analysis of influential factors

The prediction of amount from the gas emission is an important factor in Preliminary design for coal mining, which will play an active role in gas control, ventilation, drainage of gas for coal mining. By way of prediction of unique source for the prediction of amount from the gas emission in coal mining for short distance seam, the result of the prediction of amount from the gas emission for short distance seam differ largely when the seam gas geological is covered under similar conditions .The study shows that adjacent seam gas drainage rate is a major influential factor for the large difference of the result of the prediction of amount from the gas emission for short distance seam.
