A method for degassing worked out space in coal mines includes a gas line connected to vacuum pump, this is laid in mine workings that are not caved, and spurs connected to the pipeline, those are left in the worked out space. To provide maximal collection of methane and removal of the spurs of the pipeline from the caved worked out space those are protected with protective structure, this provides removal of the spurs of the pipeline after the end of degassing and prevents blocking the methane-collection openings in the spurs of the pipeline.
