摘要
通过采用分源法和矿山统计法相结合的预测方法,综合分析得出了三水平初期开采阶段工作面采用轻放工艺回采时的瓦斯涌出量,极大地指导了矿井下一步的瓦斯管理和安全生产.
By using Separate Source Method and Mine Statistic Method, the paper makes a comprehensive estimate about the gas emission, when light support top_coal caving technology is adopted in mining face during the initial phase in the third mining level, which is useful to direct the gas control and the safe production in the future.
