Description
Technical field
The present invention relates to mining tunnel drilling machine, relate in particular to the tunnel boring dirt cooling installation that goes out.
Background technology
In general coal mine gallery drilling operation, along with the depth of excavation constantly increases, owing to existing, press on high gas, highland, the soft geological condition in coal seam, very easily there is distortion and collapse hole in boring, cannot adopt continuous-flow type bore operation, can only adopt the mode of creeping into of ventilation, therefore cause a large amount of coal dust producings.There is potential safety hazard in the high temperature that in drilling process, drilling tool produces simultaneously, gas explosion accident happens occasionally, and causes the heavy losses of lives and properties, has had a strong impact on safety in production and the economic benefit of mine.Current domestic dust arrester mostly is the passive dedusting method of drilling orifice outside, common take water curtain dedusting and jet dedusting method as main, water curtain dedusting adds water spray cascade in aperture, although can play certain dustproof function, but because water spraying particles is large, Density inhomogeneity, dust removing effects is not ideal enough, and cause ponding muddy, polluted tunnel environment.Although jetting type is drilled, method has guaranteed working environment on certain procedures, still can not remove the situation that coal dust particulate is showy completely, and in the process of drilling, drill bit and development end excessive friction are generated heat simultaneously, greatly reduce the safety factor of boring.How in the enclosed environment in ore deposit, the coal dust that creeps into formation is effectively administered, reached dedusting cooling-down effect, guarantee downhole safety, become mining main contents of creeping into the tackling key problem of machinery industry emphasis.
Summary of the invention
Object of the present invention, just be to provide a kind of boring mechanic with good dedusting cooling function, prevent from polluting working environment, improve mine tunnel drilling construction operating mode, can effectively improve safety factor, reduce the dust infringement healthy to underground construction personnel, ensure the security of the lives and property, improve the economic and social benefits.
