Embodiment Construction

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0030] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 Shown, downhole dedusting method of the present invention comprises:

[0031] Step A: Continuously generate bubbles with a foaming device downhole;

[0032] Step B: draw the wind for blowing bubbles from the blower 2 for downhole ventilation;

[0033] Step C: Use the wind for blowing bubbles to blow out and diffuse the bubbles continuously generated by the foaming device, and use the blown bubbles to remove dust down the well.

[0034] Further, the wind for blowing bubbles is drawn from the side of the air blower 2, so that the normal ventilation function of the air blower is not affected.

[0035] Further, in step A, wind power is used as the power of the foaming device to reduce power cons...

Abstract

The invention provides an underground dust removal method. The underground dust removal method includes the steps that step A, bubbles are continuously generated underground with a bubbling device; step B, wind for blowing the bubbles is drawn from an underground ventilating blower; and step C, the wind for blowing the bubbles blows out and spreads the bubbles continuously generated by the bubbling device, and the blown bubbles are used for underground dust removal. The underground dust removal method has a simple structure and flexible rotation, and can ensure that a large number of bubbles continuously appear to form a bubble waterfall, thereby achieving a good dust removal effect.

Description

technical field [0001] The invention relates to the field of dust removal, in particular to an underground dust removal method, which can be used in working conditions such as mines, construction sites, and interior decoration. Background technique [0002] At present, coal dust hazard is one of the five major disasters in mines. Its hazards are mainly manifested in two aspects: one is the occupational diseases (such as pneumoconiosis) that cause frequent occurrence in the coal industry; the other is the safety hazard of coal dust explosion. According to the measurement, the dust concentration of fully mechanized coal mining in my country is as high as 4000-6000mg / m3 without taking dust prevention measures. Even if spray dust prevention measures are taken, the dust hazards in most mines are still serious. Therefore, in order to ensure the safe and efficient mining of the working face, how to reduce the concentration of coal dust more effectively is a very important technical...
