METHOD OF DUST CATCHING IN PROCESS OF COAL MASS TRANSPORTATION Russian patent published in 2013 - IPC E21F5/02 

FIELD: mining.

SUBSTANCE: method includes moistening of a transported mass by spraying of liquid via nozzles with the help of a high pressure source. At the same time the process of transported mass transportation is additionally monitored with the help of a control device arranged under a conveyor belt and switching on when it sags under weight of the transported mass, and when it actuates, the transported coal mass is irrigated with moistening liquid. Besides, the assigned task is solved since irrigation of the transported mass after actuation of the control device is carried out by means of moistening liquid supply with the help of an injection plant to nozzles of preliminary irrigation, in its turn the injection plant is switched on by opening a valve with the help of a gear pump. Additionally in process of transportation the transported coal mass is moistened in areas of overturning, for this purpose on a conveyor in areas of overturning a vertical valve is installed, with the help of which arrival of the transported mass is controlled.

EFFECT: higher automation of irrigation of transported mass on belt conveyors and in an overturning area.
