摘要
长平矿4312采煤工作面为确保U型通风上隅角风流方向稳定,瓦斯不超限,在43121巷布置可移动瓦斯抽放蛇形管,利用开启3趟蛇形管的管口负压,提高上隅角风流流向采空区的速度,从而达到治理上隅角瓦斯的目的。
In order to ensure the airflow direction stability and the no-exceeding gas on upper corner of 4312 working face using the U type ventilation in Changping Coal Mine, arrange the mobile gas extraction coiled pipe in 43121 roadway, the use of pipe negative pressure improve the upper comer airflow speed towards the gob, so as to get the purpose controlling the upper comer gas.
