运用示踪气体测量卸压煤层瓦斯抽采半径

介绍了利用SF6气体测定煤层瓦斯抽放半径的可行性和优越性,为研究卸压煤层瓦斯抽放半径提供了一种新的方法和尝试,通过实验分析和研究,发现运用该方法能够测量卸压煤层瓦斯抽放半径,优化设计抽采钻孔设计,解决了传统方法测量煤层瓦斯抽放半径的不足。

Introduced the use of SF6 gas coal seam gas drainage radius determination of the feasibility and superiority of the coal seam gas drainage radius for the study provides a new way and try, through experimental analysis and research, found that using this method to measure the coal seam gas drainage let radius, optimum design Borehole designed to address the use of traditional methods of measuring the radius of the lack of coal seam gas drainage.
