Description
Technical field:
This utility model relates to a kind of partition-type fall resistance ventilating system, belongs to underground mining mine ventilation field.
Background technology:
Domestic mine gradually strides forward to deep, causes mine ventilation resistance to increase, and ventilation difficulty increases, and in turn results in ventilation
Energy consumption increases, and production cost increases；Distinguished and admirable wayward, inside and outside, down-hole is leaked out seriously, easily causes dirty wind fresh wind series connection,
Cause underground air of poor quality, it is impossible to meet the requirement of safety in production.Traditional employing reduces roadway along journey coefficient of friction, shortening
The means such as vent line, can realize reducing mine windage, avoiding distinguished and admirable series connection, the problem in airflow regulation direction.But it is existing for many years
Field practice have shown that, although using these means notable for the regulating effect that local, mine is the most distinguished and the most admirable, but the tune distinguished and admirable to entirety
Whole effect is poor, and need to implement substantial amounts of engineering, indirectly adds mining cost.
Summary of the invention:
For the problems referred to above, this utility model provides that a kind of quantities is little, the obvious isolated fall resistance of resistance reducing effect is logical
Wind system.Solve the ventilating problem during the metal and nonmetal mining of deep mining, improve mine entirety ventilation effect
Really.Simultaneously, it is to avoid dirty wind and fresh distinguished and admirable connecting, improve drafting efficiency, improve working environment at coal mines, reduce well
The danger coefficient of lower operation.
This utility model partition-type fall resistance ventilating system, it comprises return air roadway 1, fresh wind inlet 2, air intake roadway 3, leads to
Wind structures 4, sealing coat 5, main fan 6 and dirty wind outlet 7, Ventilation Structures 4 and ventilation sealing coat 5 are by air intake roadway 3 and return air
Roadway 1 isolation separates, and fresh wind inlet 2 connects with air intake roadway 3, and return air roadway 1 connects with dirty wind outlet 7, and main fan 6 is installed
Middle section in dirty wind outlet 7.
As preferably, described sealing coat 5 available exploitation at present top, stage casing adopt tunnel, stage casing and air door, brattice
Cut off it and contact formation in associated airway structures 4 with air intake roadway 1.
As preferably, described main fan 6 is the main fan of system, for exhaust ventilation, bears the ventilation in full ore deposit.
As preferably, described air intake roadway 3 can be the air intake engineerings such as air intake courtyard, intake entry；
As preferably, described return air roadway 1 refers to the return air engineering such as return air raise, tailgate.
As preferably, described tunnel, stage casing of adopting is really as return air circuit, as the circulation circuit of dirty wind outlet 7,
It connects the return air roadway 1 of ventilating system, and choose adopt the stage casing that stage casing should be positioned near main fan 6, ventilation stage casing with
Return air raise is connected.
The beneficial effects of the utility model: 1, can effectively reduce the resistance of ventilating system, improve the drafting efficiency of system.In
All there is the problem that vent line is long, resistance is big in the mine ventilation system of deep mining, uses invention can effectively reduce system
Flowing resistance, field experience shows, it is possible to decrease to former resistant 1/2nd, substantially increase the drafting efficiency of system；
2, because forming sealing coat, fresh wind is separated with dirty wind, separates with Fei Feng district with wind district, avoids to the full extent
Dirty wind distinguished and admirable is connected with fresh, it is ensured that the environment that underground labour works, and improves the safety coefficient of exploitation；
3, conveyance system can greatly reduce implementation cost by the original roadway engineering in mine, thus reduce mine
Overall production cost.
Accompanying drawing illustrates:
For ease of explanation, this utility model is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is this utility model structural representation.
1-return air roadway；The fresh wind inlet of 2-；3-air intake roadway；4-Ventilation Structures；5-sealing coat；The main fan of 6-；7-is dirty
Wind exports.
Detailed description of the invention:
As it is shown in figure 1, this detailed description of the invention is by the following technical solutions: it comprise return air roadway 1, fresh wind inlet 2,
Air intake roadway 3, Ventilation Structures 4, sealing coat 5, main fan 6 and dirty wind outlet 7, Ventilation Structures 4 and ventilation sealing coat 5 are by air intake
Roadway 3 and return air roadway 1 isolation separate, and fresh wind inlet 2 connects with air intake roadway 3, and return air roadway 1 is with dirty wind outlet 7 even
Logical, main fan 6 is arranged on the middle section of dirty wind outlet 7.
As preferably, described sealing coat 5 available exploitation at present top, stage casing adopt tunnel, stage casing and air door, brattice
Cut off it and contact formation in associated airway structures 4 with air intake roadway 1.
As preferably, described main fan 6 is the main fan of system, for exhaust ventilation, bears the ventilation in full ore deposit.
As preferably, described air intake roadway 3 can be the air intake engineerings such as air intake courtyard, intake entry；
As preferably, described return air roadway 1 refers to the return air engineering such as return air raise, tailgate.
As preferably, described tunnel, stage casing of adopting is really as return air circuit, as the circulation circuit of dirty wind outlet 7,
It connects the return air roadway 1 of ventilating system, and choose adopt the stage casing that stage casing should be positioned near main fan 6, ventilation stage casing with
