Description
Technical Field
The utility model relates to a synthesize mechanized coal mining technology, especially relate to an adopt short wall of continuous miner to synthesize mechanized working face coal mining system.
Background
At present, the coal mining mostly adopts a comprehensive mechanized coal mining method (fully mechanized coal mining for short), which means that the whole production process of a coal mining working face (including coal breaking, coal loading, coal transporting, supporting, goaf treatment and the like) is mechanized. The main equipment of the fully mechanized mining face is as follows: coal mining machines (as coal mining equipment), flexible scraper conveyors (as working face transportation equipment), and hydraulic supports (as working face roof support equipment), which are also called as "three machines". In the three machines, the coal mining machine mainly has the functions of breaking and loading coal, the flexible scraper conveyor mainly has the function of conveying coal, and the hydraulic support mainly has the functions of supporting and goaf treatment.
The traditional longwall fully-mechanized coal mining face has the disadvantages of large number of roadways, complex equipment configuration such as coal cutting and coal transporting, various equipment types which need to be purchased and maintained by coal mine enterprises, large investment, and poor safety and adaptability.
At the present stage, continuous miner (continuous miner) is mainly used for excavation of roadways. The continuous mining machine is a comprehensive tunneling and short-wall mining device, and integrates cutting, walking, transferring and spraying dust suppression. The continuous miner consists of a cutting mechanism, a loading and transporting mechanism, a traveling mechanism, a hydraulic system, an electrical system, a cooling, spraying and dust removing device, a safety protection device and the like. The process of the continuous miner for tunneling the roadway is divided into two procedures of grooving and stacking, a driver determines the feed position of the continuous miner under the guidance of a laser direction indicator, the continuous miner tunnels on one side of the roadway, and the continuous miner retreats according to the cutting depth of the roadway to the circulating progress, and the procedure is called grooving. And then the continuous mining machine is withdrawn, adjusted to the other side of the roadway, and the rest coal wall is cut to ensure that the roadway is dug to the required width and the circulation progress, and the process is called as a 'stack mining' process. The continuous miner completes the tunneling of the roadway through the processes of grooving and stacking.
In the coal face, no suggestion is made that a continuous miner is used for comprehensive mechanized coal mining.
In view of this, the present invention is especially provided.
