Embodiment 1

[0018] Sodium dodecylbenzenesulfonate, sodium lauryl sulfate, wetting agent, foam booster, sodium hydroxymethylcellulose and water are compounded, and the weight of each component is:

[0019] Sodium dodecylbenzenesulfonate 20 kg

[0020] Sodium Lauryl Sulfate 23kg

[0021] Humectant 3kg

[0022] Foam booster 2 kg

[0023] Sodium hydroxymethyl cellulose 2 kg

[0024] 50 kg of water

[0025] After all components are mixed, stir evenly. After standing for several hours, the mixed solution becomes a transparent liquid with slightly yellow color. Take an appropriate amount of the prepared foaming agent, add 100 times the volume of water, and foam through a foaming device (wind pressure 0.6 MPa). The foam multiple is about 120 times. The particle size of the foam is extremely small and fine, the viscosity is high, and the ability to absorb dust is strong. The dust suppression rate of the foam dust suppressant with this formula can reach 98.56% for whole dust and 94.31% for ...

Abstract

The invention discloses a dust-suppression foaming agent used for coal mine excavating work surfaces. The dust-suppression foaming agent comprises the following raw material ingredients in percentage by weight: 15 to 20 percent of sodium dodecyl benzene sulfonate, 20 to 25 percent of lauryl sodium sulfate, 2 to 4 percent of wetting agent, 1 to 3 percent of foam improver, 1 to 2 percent of sodium cellulose glycolate and 50 to 60 percent of water. All ingredients are proportionally mixed and uniformly stirred at the room temperature. The generation of dust can be suppressed from a source. The invention can effectively prevent the diffusion of the dust and inhabit the occurrence of pneumoconiosis for easy-dust-generation operation places such as work surfaces of integrated mining and integrated excavating. The foam is fine and has small grain diameter and high viscosity, the dust grains with small grain diameter can be easily humidified, the absorption performance on the dust is strong, the foam coverage surface is wide, foaming times are high, the maximum foaming times can reach 12 times, the dust suppression efficiency on full dust is as high as 96 to 99 percent, and the dust suppression efficiency on respiratory dust is as high as more than 90 percent.

Description

technical field [0001] The invention relates to a dust suppressant, in particular to a dust suppressant for underground dust suppression in coal mines, which can suppress the generation of dust from the source and can be used for dust control on coal mining face. Background technique [0002] Coal mine dust reduction and dust suppression technologies mainly include spray dust removal technology, ventilation dust removal technology, coal seam water injection technology, foam dust suppression technology, etc. First, spray dust removal technology [1] The internal and external spraying device of the shearer is used to reduce dust. The internal and external spraying of the shearer is generally completed by static pressure water. When there are many water locations, the pressure will be insufficient, the atomization effect will be poor, the nozzle will be easily blocked, and the dust reduction effect will be reduced. And the dust collection rate can not meet the requirements. Sp...
