Abstract
The invention relates to a wet-type three-dimensional dust falling method for a mine conveying roadway. Three modes are adopted for dust falling of a mine underground main roadway: 1, an n-shaped frame is arranged in the main roadway at intervals, two sides and the top of the n-shaped frame are close to a coal wall, and a spray head for spraying water towards the coal wall is arranged on the n-shaped frame; 2, a net frame is arranged above a belt conveyor in the main roadway, and completely covers a conveyor belt; and 3, a material unloading point is covered by a steel hood. The wet-type three-dimensional dust falling method for the mine conveying roadway is used for conveying the main roadway underground, simple and easy to apply and low in cost, reliably applied, and can effectively reduce the probability that a worker suffers from occupational diseases.
Description
Technical field
The present invention relates to a kind of dust-removing method, particularly relate to a kind of dust-removing method that is used for the mine haulage drift.
Background technology
Coal dust or dust are one of natural calamities of harmfulness maximum in the Coal Production, and they mainly contain the harm of mine safety production and worker's health:
1, has volatile coal dust and blast under certain condition, cause casualties and endanger mine safety production.
2, personnel are if long-term transfinite coal dust or the dust of sucking is prone to suffer from the dust occupational disease, and like anthracosis or anthraco-silicosis, bronchitis etc., serious harm mine staff's is healthy.
3, dust is excessive, and visibility reduces, and causes transportation or other accident accident easily.
Each link in the Coal Production process all can produce coal dust or dust, produces the bigger place of Dust Capacity and is common in loading and unloading, transportation, respectively transports manufacturing process such as coal transfer point.
Summary of the invention
The purpose of this invention is to provide the three-dimensional dust-removing method of a kind of mine haulage drift wet type, make coal dust or dust that the main road haulage material produces obtain covering, be unlikely in big lane, to run wild, simultaneously coal dust or the dust on the humidification coal wall.
Haulage drift wet type three-dimensional dust-removing method in mine provided by the invention is to adopt following three kinds of modes that down-hole, mine Da Xiang is carried out depositing dust simultaneously:
1, in big lane, whenever keeps at a certain distance away and arrange a door type framework; The both sides of door type framework and top are near the coal wall; Said door type framework is made of the hollow pipe connection; Hollow pipe is provided with fog-spray nozzle; Utilize hose with each type framework be linked together; Hose connects feed pipe, and water is introduced in the door type framework, produces water smoke from the fog-spray nozzle ejection;
2, in big lane adhesive tape conveyor above arrange netted framework, said netted framework is fixed on through fixed mount on the support of adhesive tape conveyor, and conveyor belt is all covered;
3, the material unloading point is risen with the steel cage cover.
Wherein, described feed pipe or hose are provided with the mechanical timer valve.
Three kinds of measures of the three-dimensional dust-removing method of mine of the present invention haulage drift wet type move simultaneously, arrange that in big lane, down-hole door type framework to coal wall atomized water spray depositing dust, utilizes the water under the certain pressure effect; Mix with air or pressure wind through micropore ejection back, form vaporific water particle, water particle collides with floating dust in air; Make mine dust by moistening, increased the quality of mine dust itself, thereby improve the settling rate of mine dust; Reduce the aerial showy time of mine dust, make that the floating dust amount reduces in the air; Utilize netted framework that conveyor belt is all covered, the material dust from flying in avoiding transporting; Get up with the steel cage cover at the material unloading point, coal dust or dust can not flown upward.
Haulage drift wet type three-dimensional dust-removing method in mine of the present invention is used for the down-hole main haulage roadway, and is simple, reliable, cost is low, and the integrated environment in big lane is safer, can effectively reduce the probability that the staff suffers from occupational disease.
The specific embodiment
Haulage drift wet type three-dimensional dust-removing method in mine comprises following three partial contents:
1, in big lane, down-hole, arrange a door type framework, door type framework by have screw socket can be linked together hollow section forms, hollow section can connect mutually through screw socket, forms adjustable length type framework according to the length in tunnel.The both sides of door type framework and top be near the coal wall, and a door type framework is installed at a certain distance, up to being covered with whole tunnel.Hollow section is provided with fog-spray nozzle, and the installation quantity of fog-spray nozzle can guarantee can evenly squirt whole coal wall from the water smoke of fog-spray nozzle ejection.Utilize hose that each type framework is linked up, supply water in door type framework through the down-hole feed pipe, to coal wall atomized water spray depositing dust, supply water with the mechanical timing valve gate control simultaneously, its benefit is to take explosion precaution.
2, in big lane adhesive tape conveyor above arrange netted framework; Said netted framework is fixed on the support of adhesive tape conveyor through fixed mount; According to the length of adhesive tape conveyor, link up with a plurality of netted frameworks, the transported material part of conveyor belt is all covered.Use netted framework that three benefits are arranged, the one, net structure is convenient to distributing of gas in the coal, is unlikely to cause that the part of gas assembles; The 2nd, be convenient to personnel and observe the material traffic condition; The 3rd, can cover a large amount of coal dusts or dust.
3, the material unloading point is risen with the steel cage cover, coal dust or dust can not flown upward, can cover a large amount of coal dusts or dust.
Through above 3 measures, coal dust or dust on can humidification coal wall, the coal dust or the dust that make the material that in big lane, transports produce obtain covering, and are unlikely in big lane, running wild.
Claims (2)
1. three-dimensional dust-removing method of mine haulage drift wet type is to adopt following three kinds of modes that down-hole, mine Da Xiang is carried out depositing dust simultaneously:
1), in big lane, whenever keeps at a certain distance away and arrange a door type framework; The both sides of door type framework and top are near the coal wall; Said door type framework is made of the hollow pipe connection; Hollow pipe is provided with fog-spray nozzle; Utilize hose with each type framework be linked together; Hose connects feed pipe, and water is introduced in the door type framework, produces water smoke from the fog-spray nozzle ejection;
2), in big lane adhesive tape conveyor above arrange netted framework, said netted framework is fixed on through fixed mount on the support of adhesive tape conveyor, and conveyor belt is all covered;
3), the material unloading point is risen with the steel cage cover.
2. haulage drift wet type three-dimensional dust-removing method in mine according to claim 1 is characterized in that on described feed pipe or hose, being provided with the mechanical timer valve.
