Mine

ventilation

system

is

an

important

part

of

the

mine

production system. Whether ventilation system is reasonable

plays

a decisive role in

ensuring

the

air

supply

of

using wind

place

and

safety

production,

as

well

as

the

basic

construction

of the mine and the less expensive ventilation.

Therefore it

is crucial that establishing a ventilation system that can

not

only

meet

required

air

volume

d

uring

the

daily

production,

guarantee

the

stability

of

the

wind,

the

wind

quality

qualified,

but also in disaster period maintain ventilation equipment

reliable and stable and quickly achieve wind flow control.

矿井通风系统是矿井生产系统的重要组成部 分，通风系统是否合理，

对保证各用风地点的供风和安全生产，

以及矿井基本建设和降低通风

费用起着决定性作用。

因此建立一 个既能满足日常生产所需风量、

保

证风向稳定、风质合格

,

在灾变时期又能保持通风设备运行可靠、稳

定，能快速实现风流控制的通风系统是至关重要的。

项目任务实施：

Step 1. Project Show

A: Student(

学生

)

B: Professor Wang

（王教授）

A

：

Good morning,

Professor Wang

!

B

：

Good morning,

nice

to

meet

you!

A

：

Nice

to

meet

you, too!

I am especially

interested

in

“

mine

ventilation

system

”.

Could

you

tell me

Figure

1.

Typical

elements

of

a

main

ventilation

system

about it?

B:

Of

course.

Please look at this figure. Figure 1 depicts the essential

elements

of

a

ventilation

system

in

an

underground

mine

or

other

subsurface facility. The fresh air enters the system through

one or more downcast shafts and along intake airways to the

working

areas

where

the

majority

of

pollutants

are

added

to

the

air.

The

contaminated

air

passes

back

through

the

system

along

return airways.

The return air eventually

passes back to the

surface through the upcast shafts.

The entire line that the

airflow

passed

through

and

its

supporting

ventilation

facilities are regarded to as the mine ventilation system.

in the mine?

B: Look! There are air doors, stopping , air crossings, air

regulators and so on .

A

：

Thank you for your time.

B

：

You are welcome.

Step2. Project Implementation
