Description

The scalable tunneling boring Dust collecting net of underworkings

Technical field

The utility model relates to Dust collecting net fields, the in particular to scalable tunneling boring Dust collecting net of underworkings.

Background technique

In shaft production, transportational process, the generation of mine dust is inevitable, and mine dust is one of big disaster of mine five, The size of air chats dust content directly affects the health and range of visibility of miner, can lead to accident when serious, especially It is in the tailentry of production mine dust, and all suspension mine dusts are all blended in return to be discharged together, greatly Reduce visibility.Coal mine mine dust is broadly divided into coal dust, rock dirt and mixing dirt.Coal dust has explosivity (with regard to Donggou coal mine Speech), once it is exactly that mine is ruined people and died that explosion, which occurs, the dead group of group hurts accident, and coal dust is mainly distributed on coal working face and coal roadway tunneling Other generate the place of coal dust for working face and air return lane and each belt-conveying lane etc., and the miner of Long Term Contact coal dust, which can lead to, to be suffered from Miner lung；Coal mine rock dirt does not have explosion danger, and being mainly distributed on stone drifting working face and air return lane etc., other produce rock dirt Place, the harm of rock dirt is huge, and the miner of Long Term Contact rock dirt can lead to silicosis, and suspend aerial mine dust diameter 7.07 Micron and rock dirt below are maximum to the harm of human body；The content that mixing dirt has non-explosive to depend primarily on combustible dust, It is mainly distributed on the driving and air return lane of half-coal rock roadway, the miner of Long Term Contact can lead to pneumoconiosis.

The optimal state of mine dust control is exactly " technological innovation ", it is made not generate mine dust in process of production, but " technological innovation " this respect, at home and abroad the same industry is still the problem that do not capture instantly, secondly be exactly " wet operation " and " reduce coverage ", " wet operation " because low in cost, using, it is easy to maintain, so and our present mines use Most common construction dedusting method, but its limitation is stronger, has extraordinary dust removing effects to supporting perforating, but to coal mining The mine dust dust removing effects generated when machine is mined and when development machine tunnels are unsatisfactory；" reducing coverage " is for modernizing well work For coal mine, reducing the most effective method of coverage is exactly that tunneling boring Dust collecting net is installed near getting working face air return lane, Mainly there are " waste and scrap splicing assembly type " and " sheet group in the installation of China's underground mine industry Dust collecting net and production at present It is box-like " two kinds of forms；It is provided according to " safety regulations in coal mine ": " one must be installed within the scope of getting working face air return lane 50m to entirely Section Dust collecting net " because the universal of Mechanion greatly improves working efficiency now, Dust collecting net migrate work and Its is ordinary.But traditional Dust collecting net drawback is numerous, such as: " it cannot achieve tunneling boring and catch that dirt, structure is complicated, heavy, disassembly installation Work consuming is time-consuming, is ugly in appearance, and it is strong not meet contemporary standard construction, limitation " etc.；It furthermore is exactly individual protection, although rationally Selection personal protective equipment can effectively avoid the generation of occupational disease, but lighted in the construction ground for influencing sight because of mine dust Less than any effect.In order to overcome the problems, such as the numerous drawbacks of traditional Dust collecting net, the coverage of mine dust is effectively reduced, improves operation ring Border, thus the design of scalable tunneling boring Dust collecting net with apply in coal mine down-hole tunnel with very big practical application value and pushing away Wide meaning, for this purpose, it is proposed that the scalable tunneling boring Dust collecting net of underworkings.
