摘要
根据永天煤业矿井瓦斯赋存情况、矿井采掘部署与接替计划,对矿井瓦斯进行了分析,并采用分源预测法对不同时期分层开采的采煤工作面、掘进工作面、采区的矿井瓦斯涌出量进行了预测。分析预测结果得出,该矿上下分层开采期间均为高瓦斯矿井。
According to the occurrence laws of gas in Yongtian Coal Mining Limited Liability Company,mining plan and succession plan,mine gas was analyzed.With the application of the separate source forecasting method,this paper presents the prediction of gas emission rate from coal face,heading face and mining area in different period of slice mining.The result shows that,the mine is high gas mine during the period of slicing mining.
