Description
Technical field
The utility model relates to mine ventilation technology field, relates in particular to a kind of mine ventilation system.
Background technology
Mine ventilation system is made up of ventilation fan and ventilation network two parts.Distinguished and admirable enter mine by inlet air well head after, respectively use wind field institute through down-hole, then enter returnairshaft, discharge mine by returnairshaft, the whole route of distinguished and admirable process is called mine ventilation system.
China's mine ventilation system research starts from the Guizhou Polytechnical College of late 1970s, afterwards, the research institutions such as the Shenyang academy of China Mining University, Beijing Institute of Technology, Northeastern University, Liaoning Project Technology University and China Coal Research Institute, combine with scene is actual, divide in wind theoretical research etc. in mine ventilation system reliability and network and all carried out useful discussion.At present, the research of China's mine ventilation system, representative with the research of Liaoning Project Technology University, Xi'an Technology University and China Coal Research Institute, the large-scale of the large province of China's producing coal and the application of super-huge colliery more.
The great-leap-forward development of mining production makes the adaptive capacity of traditional mine ventilation system be challenged, continuous exploitation makes the most metalliferous mine of China reach darker level, add gushing out of deep-well hot water, the phenomenon that mine operation temperature raises is day by day obvious, often have influence on downhole safety to produce, thereupon, the returnairshaft of ventilation system return side also will constantly be deepened, roadway diameter constantly becomes large, continuous cutting returnairshaft, need time and the financial resources of at substantial, and the rock raise group of each ore bed of connection that ore bed upper section of stope is left over meets with idle or discarded in mine.
Utility model content
For all deficiencies of prior art, in order to solve the problem, now propose a kind of structure simple, utilize the outer mine group of discarded arteries and veins as the mine ventilation system of returnairshaft.
The technical solution adopted in the utility model is as follows:
A kind of mine ventilation system, comprise downcast and returnairshaft, the first mine layer, the second mine layer and the 3rd mine layer is provided with successively, the return air channel that the second rock raise that described returnairshaft comprises centralized return air system well, is communicated in the first rock raise of the first mine layer and the second mine layer and is communicated in the second mine layer and the 3rd mine layer forms between described downcast and returnairshaft.
Further, described downcast and centralized return air system well are provided with draft fan.
Further, described first rock raise and the second rock raise place are provided with draft fan.
Further, the draft fan power of described centralized return air system Jing Chu is greater than described first rock raise, the second rock raise place draft fan.
Further, described draft fan adopts single dual power supply or single power supply formula ventilation fan.
The beneficial effects of the utility model are:
1, the utility model has the simple feature of structure;
2, the utility model utilizes rock raise group in mine as returnairshaft, to have the advantages that to save the return air excavation time and dig a large amount of financial resources needed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing of the present utility model; clear, complete description is carried out to the technical solution of the utility model; based on the embodiment in the application; other roughly the same embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of the application's protection.
