摘要
结合井田的瓦斯涌出量资料,综合考虑瓦斯涌出量的开采技术因素与自然因素等影响,运用分源预测法对开滦(集团)荆各庄矿分层开采的9#煤未采区瓦斯涌出量预测研究,得出了9#煤的瓦斯涌出量与煤层标高的密切关系,确定了其误差来源,为煤层的正常开采提供重要的理论依据。
In combination with the gas emission value information of the minefield,in comprehensive consideration on the mining technical factors of the gas emission value,the natural factors and other influences,the different sources prediction method was applied to the prediction study on the gas emission value of No.9# mining block for slice mining in Jinggezhuang Mine,Kailuan Group.The close relationship between the gas emission value from No.9# mining block and the seam elevation was obtained and the error sources was determined,which could provide the important theoretical basis for the normal mining of the seam.
