Изобретение относитс к горной промышленности и может быть использован дл обеспыливани воздуха в очистных забо х угольных шахт.The invention relates to the mining industry and can be used for the dedusting of air in the clearing of coal mines.

Известен способ обеспыливани воздуха в очистном забое, при котором запыленный воздух из зоны работы комбайна отсасыгают и удал ют из забо по воздуховоду со всасывающими окнами, проложенному по всей длине лавы, аочистку воздуха производ т на примь как щем к лаве вентил щионном штреке 1J.There is a known method of dedusting air in a downhole, in which dusty air from the work area of the combine is sucked off and removed from the hole through an air duct with suction windows laid along the entire length of the lava, the air is cleaned using a ventilation duct 1J.

Недостатком способа вл етс невысока эффективность обеспыливани воздуха в забое вследствие достаточно полного захвата в отсасывающую систему всего объема запыленного воздуха.The disadvantage of this method is the low efficiency of dedusting of air in the bottomhole due to the fairly complete capture of the entire volume of dusty air into the suction system.

Известен также способ обеспыливани Воздуха в очистных забо х, осно- ванный на отсасывании запыленного воздуха из зоны работы выeмo пюй мащины и удаленииего из забо по трубопроводу, проложенному по всей длине очистного забо 2 .There is also known a method of dedusting Air in a clearing of debris, based on the suction of dusty air from the working area of the gasket and removing it from the well through a pipeline laid along the entire length of the clearing face 2.

Недостатком способа вл етс распространение взвешенной пыли по длине очистного забо ,The disadvantage of this method is the distribution of suspended dust along the length of the clearing hole,

Цель изобретени заключаетс в предотвращении распространени взвешенной пыли в забое и улучшении пылевой обстановки на рабочих местах при любом направлении выемки.The purpose of the invention is to prevent the spread of suspended dust in the face and to improve the dust situation at workplaces in any direction of excavation.

Цель достигаетс тем, что свежий воздух к выемочной машине подают с двух сторон встречными потоками и в зоне расположени машины отсасывают их суммарный объем, причем, весь объем исход щего из очистной выработки воздуха направл ют в выработку с исход щей вентил ционной струей, непосредст венно не сообщающуюс с очистной выработкой .The goal is achieved by supplying fresh air to the excavation machine from two sides by opposing streams and in the location area of the machine sucking their total volume, and the entire volume of the outgoing air from the clearing generation is directed to the outlet with outgoing air flow. communicating with clearing generation.

Чертеж по сн ет способ обеспыливани воздуха в очистном забое.The drawing illustrates a method for dedusting air in a clearing face.

Способ осуществл ют следующим образом .The method is carried out as follows.

Claims

Fresh air intended to air cleaning plant 1 is fed into it from opposite sides, for example from the top 2 and bottom 3 drifts, and is directed to the extraction car 4 by two opposing streams. In the area of the excavation machine 4, the entire volume of air the stream formed by the merger of two Hbix flows and containing the dust and gas emitted during the excavation process is sucked off and removed from the bottom (for subsequent cleaning of the pier and emission of purified air) through pipeline 5, laid along the entire length of the lava, In operation 6 with outgoing ventilation jet, directly connected with the treatment output and isolated from it, for example, ventilation bridges 7. Outgoing air is sucked out through suction inlets 8, located along the entire length of the pipeline excavation machine and then close as it progresses. The vacuum in the suction pipe, which provides the movement of the required air volume, is created due to a general depression and. By using an additional source of power, for example, a fan 9, a fan 9, complete with a dust removal device 10, installed an isolated outlet with a jet, for example on a moving platform or on a monorail, and periodically moved as the bottom of the face moved. The section of the suction pipe 11 between the entrance to the lava and the installation site of the fan is carried out in the form of removable sections to ensure the POSSIBILITY of changing the length of this section 1 sec when moving the fence for one cycle. The proposed method of dedusting air in the clearing holes allows to prevent the spread of dust in the bottom and to improve the dust situation at workplaces in any direction of the excavation. DETAILED DESCRIPTION OF THE INVENTION Claims for dedusting air in cleansing holes, based on suctioning dusty air from the working area of the excavation machine and removing it from the bottom through a pipeline laid along the entire length of the cleaning face, characterized in that in order to prevent the spread of suspended dust in the face and to improve dust conditions in the workplace at. any direction of the excavation, fresh air is supplied to the excavation machine from two sides by opposing streams, and in the location area of the machine, their total volume is sucked, and the entire volume of the outgoing air from the clearing air is directed to the outlet with outgoing air flow clearing development.
