Description

Underground mine use boring deslagging deduster
Technical field
The utility model relates to the device of dust removal by ventilation under the coal mine, is mainly used in tunnel wall coal seam dry method boring dedusting, anchor pressure spray process depositing dust, coal conveying belt transfer point under the coal mine, refers in particular to a kind of underground mine use boring deslagging deduster.
Background technology
The existence of gas is threatening the safe working of coal in the coal seam, and the gas under the coal mine in the tunnel wall boring pump drainage coal seam becomes one important step of safe coal exploitation.To some weak seams, can only dry method hole, adopt compressed air drifting dust technology, the coal dust and the compressed air that produce when making boring spray along the gap between drilling rod and the hole wall together.Though the drifting dust gas flow is little, the energy that compressed air has is big, and the gas shock power of formation is strong, and the band dust quantity is up to 3000mg/m 3More than, cause the environment of work plane very abominable, the serious threat operating personnel's is healthy; The gas density of ejection air-flow is high, and because of the height safety in production needs, the dust-removing method of drifting dust technology is forbidden exhaust fan.
In order to improve the serious problem of environmental pollution in the dry method boring, present way is the aperture dust arrester that the drilling rod sleeve pipe is set in the aperture of dry method boring, and small casing gos deep into the coal seam; Big sleeve pipe is pressed close to the tunnel wall; Ejection gets into big sleeve pipe to compressed-air actuated drifting dust along the gap between drilling rod and the small casing, and at big sleeve pipe internal spraying depositing dust, efficiency of dust collection is between 50%~60%; Though dust-laying effect is obvious, be difficult to reach working envrionment sanitary standard.At present; The aperture dedusting also has the process equipment of other form; Like multi-stage non-powered orifice dust remover (200920032546.X), mining wet type orifice dust catcher (200620110816.0); But because equipment volume is big, remove fast, dress and difficult, be difficult to adapt to the demand of bore position frequent change.
Fast development along with national economy; The demand of coal is increasing; The safe working of coal is more and more paid attention to, and tunnel wall boring pump drainage gas has become one of important measures that gas is given prominence in the prevention coal mining, so the boring workload in wall coal seam is increasing.In order to eliminate in the dry method boring procedure dust to the threat of operating worker; The development volume is little, in light weight, safe and reliable, remove and adorn fast and easily that the high-effective dust-removing device has important practical value; It can improve the working environment of work plane, reduces the labour intensity of operating worker, ensures the working interest of operating worker; Simultaneously, can improve the operating efficiency of wall boring.
