Description
Technical field
The utility model relates to a kind of air duct wind outlet unit, is specifically related to a kind of underground coal mine ventilating duct controlling type exhaust apparatus.
Background technology
China is global maximum coal producer, and the intensity of coal dust and gas explosion and number of times are also the first in the world.Along with the continuous increase of pit mining scale and mining depth, the danger that great coal dust and gas explosion occur also is increasing.Coal mine gas explosion occurs frequent, and its harmfulness occupies first of each great, pernicious and burst accident.The colliery of current China exploitation about has 48% for highly gassy mine and Gas Outburst mine.According to adding up in recent years, the gas occurred in tunneling process and dust explosion accident account for the 60-70% of mine gas dust explosion accident sum.Gas is the mist of the compositions such as methane, carbon dioxide and the nitrogen of overflowing from coal seam, and coal road (half coal road) driving face is the working region first entering coal seam, is therefore gas and dust explosion accident region the most frequently.
Coal driving is a dead face, ventilation circuit is imperfect, to be local ventilation system by being made up of booster and air duct be pressed into end regions fresh distinguished and admirablely realizes for dilution and the dust produced when getting rid of the gas and operation gushed out from coal body, local ventilation system draft type, position and air outlet speed directly will affect tunneling ventilation distribution of air flow situation, and then have impact on the gas density regularity of distribution and ventilation watt effect.As can be seen here, along with coal mining popularization, Driving Face in Coal Tunnel local ventilation situation is had higher requirement.
Because " safety regulations in coal mine " only defines the rational wind speed range of driving face and air outlet distance termination distance.Therefore, it is implement local ventilation overall control that colliery solves high speed big cross section Driving Face in Coal Tunnel to the mode that ventilation requirement increases, and namely improves constantly local ventilation acc power and strengthens air duct diameter.And driving face air quantity excessively strengthens, also easily cause circulated air, local, working region wind speed too high, the phenomenons such as condition of work deterioration.The local ventilation mode implementing the air quantity overall control of extensive style can not adapt to the high speed development of colliery mining method.According to coal roadway tunneling termination flow field flow mechanism, tunneling ventilation and gas and the coal dust process of intercoupling of migrating is carried out fine-grained management and necessitated.
The coal seam gas-bearing capacity increase etc. that the use of the increase of coal road length, the increase of tunnel sectional area, tunneling method change, fltting speed increase, large equipment and well depth increase cause, this all makes coal roadway tunneling local ventilation amount require to strengthen, and the air quantity overall control local ventilation implementing extensive style can not adapt to the high speed development of colliery mining method.
