【摘要】 利用矿井采掘区煤层瓦斯含量实测值 ,在瓦斯地质定性分析基础上 ,通过丰富翔实的钻孔资料建立井田未采区适用的煤层瓦斯含量预测公式 ,从而达到对井田煤层瓦斯含量预测的目的。为大型低瓦斯矿井煤层瓦斯含量预测提供了思路和方法更多还原

【Abstract】 According to the field survey data of the gas contentin the m ining areas and the qualitative analysis of gas content,the prediction formula of gas content in coal seam s,which can be used for unmining areas,has been obtained by certain method with a variety of drilling data.The authors intend to predictthe gas content in coal seams of the coal field and provide a constructive proposal for gas content prediction in coal seams of the large- sized coal mines.更多还原
