据俄刊《煤》杂志1994年第1期报道,莫斯科矿业学院等单位所进行的观测研究表明,回采工作面风流中的含尘量是随着采煤机割煤牵引速度的加快而呈下降趋势的,而不是象原先许多通风专家所断定的那样:随着割煤牵引速度的提高,回采工作面风流中的含尘量将增大。 According to the Russian magazine “Coal” magazine in 1994 No. 1 reported that the Moscow Mining Institute and other units conducted by the observational studies show that the mining face Merry flow of dust content is as coal miner cutting speed is accelerated and declined Trend, rather than as many previous ventilation experts have concluded: As the speed of coal-cutting traction increases, the amount of dust in the return airflow to the working face will increase.
