Method for pumping and exhausting gas of coal beds in front of parallel adit and main cave by means of parallel adit drilling construction

The invention discloses a method for pumping and exhausting gas of coal beds in front of a parallel adit and a main cave by means of parallel adit drilling construction. The method comprises the steps that (1) construction of the parallel adit is conducted before construction of the main cave till an outburst elimination position in front of a coal measure stratum is reached; (2) a working chamber is formed in the side, close to the main cave, of the interior of the parallel adit; (3) punching is conducted in the parallel adit area of a parallel adit face and then pumping and exhausting are conducted in the parallel adit area of the parallel adit face, so that outburst elimination is completed; (4) pumping and exhausting holes in the main cave area are punched with the working chamber as the starting point during pumping and exhausting of the parallel adit; (5) after outburst elimination of the parallel adit succeeds, construction of the pumping and exhausting holes in the main cave area is completed and pump
