摘要
随着矿井开采深度的增加和开采强度的扩大,以瓦斯含量高、瓦斯压力高、瓦斯涌出量大为主要特征瓦斯问题日益突出。为了研究进入深部环境后高产高效工作面的瓦斯涌出规律,通过在试验高产高效工作面布置测点,实测代表性测点的瓦斯特征参数,分析研究回采面内瓦斯特征参数倾向、走向波动规律,以及充分结合工作面内瓦斯涌出的不均衡性等,进而得到深部环境高产高效工作面瓦斯涌出规律,为矿井的安全高效开采提供必备的依据。
Along with increasing of mining depth and intensity, the gas issues mainly characterized by high gas content and pressure, large gas emission amount are increasingly prominent. To study the high yield and high efficiency working face gas emission pattern under deep environment, through experimental high yield and high efficiency working face measuring point layout has measured gas characteristic parameters of representative points. Then the gas characterized parameters dip and strike fluctuation pattern within stoping face have been analyzed. Fully combined with disequilibrium of gas emission in stoping face etc., accordingly have obtained deep environment high yield and high efficiency working face gas emission pattern. The study has provided necessary basis for mine safe and efficient exploitation.
