Problems solved by technology

In 2008, the Xinwen Mining Bureau imported auger shearers from abroad, and successively conducted auger mining tests in the 1203 west drilling face of Nanye Coal Mine and the 1701 working face of Panxi Coal Mine. Many deficiencies: (1) The docking of the drill pipe is difficult, the docking time is long, and the output is low; (2) The drilling power of the drill bit is provided by the helical drill pipe, the torque is large, and the drilling depth is generally 40-50 meters; (3) It is easy to produce Phenomenon of pressure drilling and buried drilling tools; (4) Easy to fall off between two sections of drill pipe; (5) One-sided mining of roadway, high driving rate of 10,000 tons of coal

Description

technical field [0001] The invention discloses a self-propelled and bi-directional drilling coal mining machine, which belongs to the technical field of coal mining machine design and application. Background technique [0002] At present, in the mining technology of thin and extremely thin coal seams at home and abroad, there are basically blast mining, high-grade general mining, comprehensive mechanized coal mining with drum shearer, comprehensive mechanized coal mining with coal plow, and auger coal mining. Blast mining, high-grade general mining, comprehensive mechanized coal mining with drum shearers, and comprehensive mechanized coal mining with plows all require workers to enter the working face, and single hydraulic props or hydraulic supports are required to support the roof. The equipment is numerous and complex. Large one-time investment. At the same time, due to the small thickness of thin and ultra-thin coal seams, small working space and poor working environmen...
