深部厚煤层综放开采瓦斯抽采分析

Analysis on Gas Drainage in Fully Mechanized Top Coal Caving Mining of Deep Thick Coal Seams

以深部厚煤层综放开采瓦斯抽采为对象开展探究。结合具体工程实际,在进行瓦斯涌出量预测分析的基础上,设计了多种瓦斯抽采工艺相结合的瓦斯综合防治措施,并对其实际应用效果进行检测,希望能为其他矿井相似问题的治理提供帮助。

This paper disscussed the gas drainage in fully mechanized top coal caving mining of deep thick coal seams.Combined with the specific engineering practice,based on the prediction and analysis of gas emission,the comprehensive gas prevention and control measures combined with a variety of gas drainage processes were designed,and its practical application effect was tested,hoping to provide help for the treatment of similar problems in other mines.
