露天矿工作面的通风、降尘和洒水等问题是迫切需要解决的。可以使用УМП—1A型装置(见图1)解决这个问题。苏联彼尔姆矿山机械制造厂制造的УМП—1A型通风装置的主要技术参数是:AB—2型飞机螺旋桨;风流射程为350米;喷水距离为70米;喷水量为140米~3/小时;储水缶的容量为30米~3;洒水带的宽度为12米;使用的汽车为БелA3—548型。 УМП—1A型装置可形成的风流量为280米~3/秒,通过喷咀喷水时,能形成效果 Open-pit mine ventilation, dust and water and other issues is an urgent need to be resolved. You can use the УМП-1A type device (see Figure 1) to solve this problem. The main technical parameters of the УМП-1A ventilator manufactured by the Perm mining machinery factory in the Soviet Union are: AB-2 aircraft propeller; wind range of 350 m; water spray distance of 70 m; water spray volume of 140 m ~ 3 / Hour; storage capacity of 30 meters ~ 3; sprinkler width of 12 meters; used car Бел A3-548 type. УМП-1A type of device can form the wind flow of 280 m ~ 3 / s, through the nozzle when sprayed to form the effect
