The invention discloses a coal mine underground gas extracting hole-drilling double-channel direct-reversed circulation water vapor braid. The coal mine underground gas extracting hole-drilling double-channel direct-reversed circulation water vapor braid comprises an outer tube hollow shaft (1), an inner tube assembly (3), a guiding sealing box (11) and a gang drilling cuttings sealing box (17). The inner tube assembly (3) is plugged in the outer tube hollow shaft (1) to form a rotatable bi-layer structure, the outer tube hollow shaft (1), the guiding sealing box (11) and the gang drilling cuttings sealing box (17) are connected together through screw threads, and a quick coupling (10) is arranged on the guiding sealing box (11). According to the coal mine underground gas extracting hole-drilling double-channel direct-reversed circulation water vapor braid, the volume is small, the weight is light, and the rotation is flexible; the guiding effect is good, the bearing operation is smooth and steady, and the high-speed revolution can be met; and the sealing performance is good, the circulation is leak-tight, the working performance is stable, and the assemble and un-assemble is lightweight and labor-saving.
