在阿巴伊勒斯基鑛区、開掘探鑛水平坑道之時,曾試驗過新創的閉塞坑道換氣法。這個方法的特點,是下使用扇風機,而是利用向坑內运風的空氣壓縮機,和送風幹管,將坑內有害气体抽出。也就是放炮後的煙氣,順着50mm直徑的导氣管子,不通過压縮空氣的风桶(氣罐),直接從空氣壓縮機的吸风管 At the Abailessi mines, a newly created block tunnel evacuation was tested at the time of digging prospecting levels. This method is characterized by the use of fans under the fan, but the use of wind to the pit air compressor, and air supply pipe, the pit of harmful gases out. That is, after the blast of flue gas, along the 50mm diameter gas pipe, not through the compressed air cylinder (gas tank), directly from the air compressor suction duct
