Abstract
1. Способ образования тумана при подземной разработке, при котором воду без добавления воздуха под давлением минимум 200 бар пропускают по меньшей мере через одно сопло, а затем подают на отражающую поверхность для распыления в виде капелек тумана. ! 2. Способ по п.1, отличающийся тем, что отражающую поверхность выполняют под углом, в частности под тупым углом к оси сопла. ! 3. Способ по п.1, отличающийся тем, что воду пропускают через отверстие диаметром менее 1 мм. !4. Способ по п.1, отличающийся тем, что воду пропускают через сопло под давлением минимум 300 бар. ! 5. Способ по любому из пп.1-4, отличающийся тем, что для образования тумана в сухом воздухе воду пропускают по меньшей мере через одно сопло с большим объемным расходом, а для поддержания тумана воду пропускают по крайней мере через одно сопло с меньшим объемным расходом. ! 6. Устройство для осуществления способа по любому из пп.1-5, отличающееся тем, что оно содержит цельный конструктивный элемент (10), в котором предусмотрен по меньшей мере один канал (12) сопла и на котором предусмотрена по меньшей мере одна относящаяся к нему отражающая поверхность (16), проходящая под углом к каналу сопла. ! 7. Устройство по п.6, отличающееся тем, что отражающая поверхность (16) является плоской. ! 8. Устройство по п.6 или 7, отличающееся тем, что отражающая поверхность (16) по меньшей мере местами ограничена острой кромкой. ! 9. Устройство по п.6, отличающееся тем, что отражающая поверхность (16) заканчивается на удалении нескольких миллиметров от точки пересечения с осью канала (12) сопла. ! 10. Устройство по п.8, отличающееся тем, что отражающая поверхность (16) заканчивается на удалении нескольких милл� 1. A method of forming fog during underground mining, in which water without adding air under pressure of at least 200 bar is passed through at least one nozzle, and then fed to a reflective surface for spraying in the form of mist droplets. ! 2. The method according to claim 1, characterized in that the reflective surface is performed at an angle, in particular at an obtuse angle to the axis of the nozzle. ! 3. The method according to claim 1, characterized in that the water is passed through an opening with a diameter of less than 1 mm !four. The method according to claim 1, characterized in that the water is passed through a nozzle under a pressure of at least 300 bar. ! 5. The method according to any one of claims 1 to 4, characterized in that for the formation of fog in dry air, water is passed through at least one nozzle with a large volume flow, and to maintain fog, water is passed through at least one nozzle with a lower volume expense. ! 6. A device for implementing the method according to any one of claims 1 to 5, characterized in that it comprises an integral structural element (10), in which at least one nozzle channel (12) is provided and on which at least one related to reflecting surface (16) passing at an angle to the nozzle channel. ! 7. The device according to claim 6, characterized in that the reflective surface (16) is flat. ! 8. The device according to claim 6 or 7, characterized in that the reflective surface (16) is at least partially bounded by a sharp edge. ! 9. The device according to claim 6, characterized in that the reflecting surface (16) ends at a distance of several millimeters from the point of intersection with the axis of the nozzle channel (12). ! 10. The device according to claim 8, characterized in that the reflective surface (16) ends at a distance of several mill�
