The invention relates to a method for extracting coal bed methane through down-hole bedding long borehole consecutive cave building and a hydraulic mechanical drill with the diameter changed and enlarged while drilling. A coal bed bedding long borehole is combined with a cave building technology, and the permeability of low-permeable coal reservoirs and the coal bed borehole extraction capacity are improved. A hole is opened at 1 / 3 coal thickness or 1.5m upwards away from the coal heading floor on the extracting drill site coal wall of an underground coal mine along with the coal bed, the hydraulic mechanical drill with the diameter changed and enlarged while drilling performs cave building on the borehole from inside to outside successively after the borehole reaches the preset depth, and the cave diameters and distances can be calculated through formulas. Coal bed stresses around the cave are released and coal bed prior cracks are widened and lengthened after the caves are completed, tensional and shear failures occur to the coal bed, novel cracks are produced, and accordingly, the coal bed crack connectivity is increased, the permeability is improved, the coal bed methane can be depressurized and desorbed rapidly, the coal bed methane extracting efficiency is improved dramatically, and the coal bed methane extracting time is shortened.

The invention relates to a super-automatic pipe reaming production line, and relates to the field of reaming machines. The super-automatic pipe reaming production line comprises a feeding assembly, a reaming assembly, a rotating assembly and a receiving device. The feeding assembly is located on one side of the reaming assembly, the receiving device is located on the other side of the reaming assembly, and the rotating assembly is located between the feeding assembly and the receiving device and is connected with the feeding assembly. The rotating assembly comprises a rotating plate, a rotating rod and a rotating motor, and the rotating plate is located between the feeding assembly and a material collecting box and connected with the feeding assembly. The rotating rod penetrates through one corner of the rotating plate and is fixedly connected with the rotating plate, and a driving shaft of the rotating motor is fixedly connected with the rotating rod. The receiving device is located on the side, away from the reaming assembly, of the rotating plate and connected with the rotating motor. The super-automatic pipe reaming production line has the advantages that full-automatic receiving and boxing of pipelines are achieved in the whole receiving process, workers do not need to count the number or box pipelines, and time and labor are saved.
