Zusammenfassung:	The present disclosure relates to a method and device for ensuring working conditions along a longwall face of a longwall mine. A longwall installation unit (5; 16) configured to form a longwall installation assembly (4; 17) together with a plurality of longwall installation units (5; 16) of the same kind may comprise a dilution gas nozzle (30, 30') installed in the longwall installation unit (5; 16) and configured to be fluidly connected to a compressor device. Dilution gas provided by dilution gas nozzle (30) may locally dilute methane gas, for example, in response to a measured methane gas concentration or concentration trend, and thereby ensure working conditions for man and machine.
