在爆破过程中,骤然产生大量呼吸性粉尘,需要采取专门措施加以抑制。1964年以前,西德煤矿一直使用喷雾和区域降尘法抑尘,其后唯一的措施是使用了能粘附粉尘的炮泥,它的优点是可在前面两种方法不能奏效的情况下使用。由于通常使用的这种炮泥材料只能在一定限度内提高降尘效率或抑尘,因此人们就着手采用其它的方法和材料来进行试验。 In the blasting process, a sudden a large number of respiratory dust, need to take special measures to be suppressed. Before 1964, West Germany Coal Mine has been using the spray and regional dust suppression dust suppression, then the only measure is to use the dust can be attached to the mud, it has the advantage of the preceding two methods can not be used under the circumstances. Since commonly used such stemming materials can only increase the efficiency of dust reduction or dust suppression to a certain extent, other methods and materials have been put into operation.
