Abstract

The invention relates to mining. The goal is to increase the efficiency of dust suppression. For this purpose, a straight collector with flat jet nozzles located along it is installed on the body of the combine and along the bottom. The nozzle flares are directed at an acute angle to the face of the lava along the ventilation flow passing through the lava. The linear collector is installed at an acute angle to the bottom of the lava, the top of which is located along the ventilation flow. At the same time, torches of flat-jet nozzles of a rectangular collector overlap each other in a plane perpendicular to the longitudinal axis of the shearer. Thus, this method makes it possible to use the ejecting properties of a flat plume of sprayed liquid for wetting dust and feeding it in the form of sludge drops to the bottom. 1 il.

Description

The invention relates to mining and can be used to suppress dust in refining combines of coal mines and mines.

The purpose of the invention is to increase the dust suppression efficiency due to the ejecting properties of the Torches of the sprayed liquid.

The use of the ejecting properties of a flat plume of sprayed liquid for wetting dust and feeding it in the form of droplets of sludge to the bottom increases the efficiency of suppressing dust during operation of mining equipment,

The drawing shows a diagram of the suppression of dust during operation of the cleaning

combine and air flow, top view.

The dust suppression system consists of flat-jet nozzles 1 placed in intervals on a straight line collector 2 in the form of a rigid water supply system located on the top cover of the combine body at an acute angle to the bottom of the lava. At the same time, the top of the angle (not shown) is located along the ventilation flow 3. The nozzles 1 form torches A of the sprayed liquid at water supply, directed at an acute angle of 5 to the bottom of the lava, and the flat jet nozzles overlap each other in the plane

pemdicular longitudinal axis of the shearer. The dust suppression system also contains nozzles 6, which created a water curtain 7 Sheltering screws 8 of the combine.

Dusty air moving 6 tons of screws 8 of the combine under the action of the ventilation flow 3 enters the zone of action of the first nozzle 1 along its movement, slightly changing its direction, is moistened with a torch b of the sprayed liquid, and at the same time it is ejected and thrown onto the face sludge drops. Further, moving along the ventilation duct, the portion of dusty air passing through the torch of the first nozzle enters the zone of action of the torch of the second nozzle 1, where the process of wetting dust, ejection and dropping of sludge droplets on the bottom is repeated. As it proceeds through each interval (spaced torches of the sprayed liquid (the number of nozzles is determined on the basis of the required degree of air purification from dust), the dust free air moves along the face in the ventilation flow, and the sludge and individual

the dust particles due to the ejecting properties of the torches fall on the wall of the albo and flow down onto the soil of the lava. Formula of the invention

A method for suppressing dust during the operation of shearers, including creating a water curtain around augers using flat-jet nozzles mounted on a collector fixed to the body of the combine, characterized in that, to increase the efficiency of dust suppression, a linear line is installed on the body of the combine and along the laboratory. a collector with flat jet nozzles arranged along it, the flares of which direct at an acute angle to the bottom of the lava along the flow of the ventilation stream passing through the lava, with straight lines a collector mounted to the bottom of the lava-acute angle, which vermina arranged downstream of the venting flow and torch angle flat rectangular collector nozzles overlap each other in a plane perpendicular to the longitudinal axis of the cleaning kombayna.1
