The invention discloses a guardless automatic coal feeding system and method. The system comprises a coal feeding sensation device, a coal feeding controller and an under well monitoring center computer, wherein the coal feeding sensation device is mounted at a coal feeding hole of a coal feeding working surface hydraulic bracket and is used for acquiring coal feeding data; the under well monitoring center computer is in communication connection with the coal feeding controller; the coal feeding controller is used for receiving coal feeding data and is used for transmitting the coal feeding data to the under well monitoring center computer; the under well monitoring center computer is used for transmitting control instructions to the coal feeding controller according to the coal feeding data; and the coal feeding controller is used for controlling the coal feeding working surface hydraulic bracket to complete automatic coal feeding according to the control instruction. By adopting themethod and the system, automatic coal feeding is achieved. The guardless automatic coal feeding system disclosed by the invention is capable of achieving guardless automatic coal feeding control and is good in coal feeding effect, high in efficiency, low in cost and high in security coefficient.
Description
technical field [0001] The invention relates to the technical field of automatic coal mining, in particular to an unattended automatic coal discharge system and method. Background technique [0002] In coal mine production, the production environment of the working face is harsh, and the health and safety of the staff are often not guaranteed. A large amount of dust generated during the mining of the working face has caused great harm to the physical and mental health of the working face workers. At present, some coal mining enterprises realize automatic coal mining through the automatic control of hydraulic supports and shearers in the coal mining face, so as to realize mining with few people or even no one at the working face to a certain extent. However, for the coal-drawing working face, because the coal-drawing operation environment is very complicated and the dust has a great influence, it still relies on manual operation on the spot based on feeling and experience, re...
