近十多年来,苏联露天矿山的开采比重迅速提高,开采深度不断增加,采场的大气污染问题也日益严重。据苏联一些深凹露天矿统计,由于采场大气污染每年被迫停产的时间达30余天,占年工作天数的10~12%,当气压低、风速小的时候,露天矿的粉尘烟雾数日不散,有害成分无法自然排出,空气能见度只有10米。采用汽车运输的矿山,汽车排气的污染更为突出。例如,勃里雅文露天矿自卸汽车驾驶室内丙烯醛含量超过卫生标准4~11倍。为此,苏联从五十年代末期开始,对露天矿的机械通风问题进行了研究。
In the past decade or so, the proportion of open-pit mines in the Soviet Union has been rapidly raised, the depth of mining has been constantly increasing, and the problem of atmospheric pollution in the stope has become increasingly serious. According to the statistics from some deep-open open-pit mines in the Soviet Union, the air pollution in the stope is forced to stop production for more than 30 days each year, accounting for 10% to 12% of the annual working days. When the air pressure is low and the wind speed is small, Not scattered, harmful components can not be naturally discharged, the visibility of air is only 10 meters. The use of motor transport mines, automobile exhaust pollution is more prominent. For example, the Acrolein in the cockpit of the Brigade Open-pit mines exceeds 4 to 11 times the hygiene standard. To this end, the Soviet Union from the late fifties began to study the mechanical ventilation of open-pit mines.
