摘要
在采用分源预测法预测矿井回采工作面瓦斯涌出量基础上,结合佳瑞矿区邻近矿井工作面实际瓦斯涌出源构成比重,对相应部分的瓦斯涌出预测结果进行修正,使得首采工作面瓦斯涌出量预测结果更符合实际情况,为以后矿井工作面配风及瓦斯治理工作提供科学依据。
The points in the forecast method of forecasting mine mining source mining based on the gas emission,combined with the beautiful red mine mining area adjacent working gas emission source constitute actual proportion,the corresponding part of the gas emission forecast results are fixed,makes the first mining face to forecast the gas emission results more tally with the actual situation,after working for mine with the wind and the gas treatment work provide the scientific basis.
