铁法矿区采空区封闭抽采瓦斯技术

Technologies for the Worked-out Area Closure and Gas Drainage from Gob in Tiefa Mining Area

采空区抽采瓦斯作为重要的可利用气源,日趋受到重视,采空区的封闭质量是抽采瓦斯效果的关键因素,通过对铁法矿区采空区封闭技术和抽采方法的探讨,确定最佳的采空区封闭抽采模式。

Gas drained from the mine-out area is regarded as an important useable gas source,and more and more attention is paid to this issue. The key to improving effectiveness of gas drainage is the quality of closing of the gob. In the light of discussions on technology for closing the gob and gas drainage method in Tiefa mining area,the authors have determined the optimal model for closing gob and gas drainage.
