Technical Field

The utility model relates to a mine construction equipment technical field, concretely relates to mining anchor of digging is even adopted quick-witted dust device.

Background

In the process of mining, a large amount of dust is generated, the mining operation is a main process for generating the dust, the dust generation amount accounts for more than 80 percent of the total dust, and the physical and psychological health of workers and the safety production of enterprises are seriously harmed. Taking the coal mine industry as an example, according to the incomplete statistics of the Ministry of health, the detection rate of pneumoconiosis in coal mines in China is up to 35 thousands of patients, the detection rate of pneumoconiosis is up to 7.2%, the detection rate is increased at the speed of more than 1 ten thousands of patients per year, and about 3000 patients die from pneumoconiosis every year. Dust causes not only pneumoconiosis of dust receiving workers, but also serious and serious malignant explosion accidents, and according to incomplete statistics, the number of accidents of serious coal dust explosion in China is 15 since 2000, and 960 people die. Great pain is brought to miners and families, huge loss is caused to enterprises and countries, and meanwhile bad influence is caused to the stable and harmonious development of the society. In order to prevent and control dust, technologies such as coal seam water injection, spray dust settling, dust removal by a dust remover, ventilation dust removal, chemical dust suppression and the like are widely applied to underground coal mines at present, and although the dust removal technologies play an important role in improving underground operation environment, protecting worker health and preventing mine dust accidents, the dust removal efficiency of the technologies is low, so that mine dust disasters are serious in China.

At present, foam dust suppression is mostly adopted in mine excavation work, compared with other wet dust suppression modes, the water consumption for foam dust suppression can be reduced by 50% -80%, the dust suppression efficiency is improved by 3-5 times compared with the modes of spraying, sprinkling and the like, and the foam dust suppression has the following characteristics:

1) The foam can cover the dust source without gaps, and the dust is prevented from diffusing outwards fundamentally;

2) After the liquid forms foams, the total area and the total surface area are greatly increased, the collision efficiency with dust is increased, and the working environment of the underground mining face is purified;

3) The liquid film of the foam contains a special additive, so that the wetting performance of the dust can be changed rapidly, and the wetting speed of the dust is increased;

4) The foam has good viscosity, and dust can be quickly adhered to the foam after contacting the foam;

5) The foaming agent penetrates into the coal pore cracks, and the foam covers the coal wall and the coal falling, so that the gas in the coal can be effectively inhibited from being diffused, and the gas concentration of a tunneling working face is reduced.

The existing foam dust suppression equipment has some defects in use, so that a foam dust suppression device which is more convenient to use and has a better dust suppression effect is needed.
