引进算法的分源预测法在安全高效矿井中的应用

Application of introduction method separated resources prediction method to high gassy mine

以李店矿区的安全高效工作面为研究对象,在现场调研和实测的基础上,通过采用引进算法的分源法,确定了矿井北部和南部的瓦斯涌出量,为矿井通风设计、瓦斯抽采等提供了理论基础数据。同时根据安全高效工作面瓦斯涌出特点,引进煤运至地表时残存瓦斯含量损失率这一系数,进一步完善和发展了分源预测法,提高了预测精度。

Taking the high gassy coal mining face in Lidian Mine as the study object,base on the site investigation and site survey,the separated resources method of the introduction algorithm was applied to determine the gas emission values of the north part and south part of the mine which could provide the theoretical basic data for the mine ventilation design and gas drainage.Meanwhile,according to the gas emission features of the high gassy coal mining face,with the introduction of the residual gas content lost rate when the coal transported to the surface ground,the separated resources prediction method could be well improved and developed and the prediction accuracy could be improved.
