Abstract
The invention relates to a spraying and dust falling device in a coal mine, belonging to the technical field of coal production industry and mainly aiming at reducing and eradicating a great amount of coal dust generated in the process of coal production, and eradicating the safe problem and threat of work body which are brought by the coal dust in the process of coal production. The technical scheme of the invention is as follows: a spraying device and spraying equipment are installed on a coal excavating equipment; when the coal mining equipment is used for excavating coals, the spraying device sprays the spraying materials to a coal wall and a coal cutting position to simultaneously excavate the coals and spray; the spraying materials are conveyed to the spraying device through a conveyer system and the spraying equipment; the spraying device, the spraying equipment and the spraying materials synchronically propel along with propelling of a working face for excavating the coals; and the spraying materials have a complete preparation system, and is communicated to the conveyer system through the preparation system. The invention aims at solving the technical problems of controlling speed of spraying the spraying materials to the coal wall and the coal cutting position, selecting optimum diameter of particles, selecting optimum adhesion of the spraying materials on the coal wall and the coal cutting position and selecting the proper spraying materials to absorb the dust coal.
Description
The present invention is: spraying and dust falling device in coal mine.
Technical field: be applied to coal industry.
Background technology:,, in the coal mining process, produce a large amount of coal dusts because the ature of coal religion is soft in the Coal Production field.The existence danger of coal dust coerces Safety of Coal Mine Production and the workman is healthy.The method of existing reduction coal dust can't fundamentally be eliminated the existence of coal dust fully.The present invention: spraying and dust falling device in coal mine makes every effort to eliminate fully the existence of coal dust on the root of coal dust generation.
Summary of the invention: (1) has been invented with spraying method and has been reduced and the elimination coal dust.
(2) invented spray equipment and spraying equipment are installed on the coal excavation apparatus, when coal excavation apparatus was mined, spray equipment sprayed to rib and coal cutting place with sprayed on material, realized mining and spraying is carried out simultaneously
(3) invent sprayed on material and in spraying process, do not produced dust, sprayed on material should have the character of absorption coal dust, sprayed on material can be selected the coal grain for use, and sprayed on material also can be selected for use and reduce or eliminate hazardous substances sulphur (S) in the ature of coal and reduce the material of ash content in the ature of coal, and sprayed on material is granular.Sprayed on material can be a kind of raw material, also can be the mixing of several raw materials, and sprayed on material adsorbs coal dust by spraying and dust falling and sprayed on material, the time of spraying, and sprayed on material is mixed in transportation outward together in the raw coal.Sprayed on material should not reduce the character of beneficiating ingredient in the raw coal, but can reduce the character of harmful components in the raw coal.
(4) invented sprayed on material is carried to spray equipment by the haul system, the haul system pushes ahead also with coal-face and advances synchronously.
(5) invented and have complete preparation system to produce required sprayed on material, sprayed on material is communicated to the haul system by preparation system.
The specific embodiment: on the work plane that utilizes coal excavation apparatus to mine, spray equipment and spraying equipment are installed on coal excavation apparatus, sprayed on material is transported in the spray equipment by spraying equipment by the haul system, when coal excavation apparatus is mined, spray equipment sprays to rib and coal cutting place with sprayed on material, along with coal-face is pushed ahead, coal excavation apparatus is pushed ahead; Spray equipment and spraying equipment, spraying haul system also pushes ahead synchronously with coal excavation apparatus.Have complete preparation system to produce required sprayed on material, sprayed on material is communicated to the haul system by preparation system.
