戊8煤层瓦斯涌出分源预测与防治

Gas Emission Sub-Source Prediction and Prevention of Five 8 Coal Seam

介绍了平顶山矿区六矿煤田主采戊8煤层瓦斯涌出分源预测的方法。运用现场实测、对比分析等技术手段,对戊8煤层邻近层瓦斯涌出影响及开采层瓦斯异常带瓦斯涌出量进行分源预测,针对瓦斯涌出规律,采取防范措施,解决戊8煤层关键回采技术,达到了安全高效的目的。

This paper introduces the gas emission sub-sources prediction methods of Five 8 coal seam at No. 6 coal mine of Pingdingshan coal field. By use of techniques such as field measurement and comparative analysis, sub-source prediction is conducted for influence on gas out-flow at surrounding seam and abnormal gas emission at mining layers. In light of gas emission law, preventive measures have been taken to address the critical recovery problems in combination with key recovering technology, to bring about safe and efficient mining.
