Table-I Major mining accidents in the last decade
When the report of the Union of
Turkish Engineers and Architects
in Table 1 on the mining accidents
in 2014 is examined, it is seen
that about 1000 miners have lost
their lives in the last 10 years.
There are two major reasons for
these mining accidents. One of
these reasons is the explosion of
the gris, and the other is the fire.
It will be overcomed by this
project, M-MATEKS.

3.
It is aimed to predict and prevent the ongoing mining accidents despite the
fact that many studies have been done in this work which is done by way of
the literature study and which is made continuously in our country and in
the world.

4.
It has been seen that after the study of M-MATEKS, which was passed on
after the increasing mining accidents, the literature was not designed before.
With M-MATEKS, it is aimed to close this gap. This work;
 Wristband design
 The design of the mine that the wristband will provide maximum
efficiency to human beings
 Interface design
will be examined in three main sections.

5.
Wristband design;
1. The area where the carbon monoxide gas sensor
is located
2. The region that will allow the methane gas sensor
to receive data from the media
3. The zone that will allow the heart rate sensor to
receive data from the media
4. Protective cap
5. The area where the Bluetooth module and
Arduino-Nano will be found
Although many materials are used in the wristband,
the weight of the wristband is approximately 125
grams and the miner's normal working tempos is not

The heart rate sensor uses four basic technical components
to measure heart rate:
I. Optical Transmitter
Optical transmitters are made using LEDs. These LEDs are
responsible for sending light under deep. The blood stream
dissipates this incoming light and the instrument measures
the distribution of this light.
II. Digital Signal Processor (DSP)
The digital signal processor collects the light reflected back
by distributing the blood flow, and gives the output in the
form of 1 and 0 to get meaningful heart rate data.
III. Accelerometer
Accelerometer is an instrument for measuring motion. In
the pulse sensor, it measures blood motion and works in
cooperation with the digital signal processor to help achieve
more accurate results.
IV. Algorithms
The algorithms process motion-tolerated heart rate data

The sensors can measure up to 10000
ppm. These sensors output an analog
voltage output according to the density
of the gas. The measurement of
methane gas, one of the biggest causes
of the explosion of the glaze that may
be experienced in the mine, allows us
to prevent these explosions. The use of
this sensor will have a vital proposition
when it is thought how lethal the
carbon monoxide gas produced by the
fire is.Figure-III MQ-4 and MQ-7 Sensor

8.
The HC-05 Bluetooth module used
is for wireless serial communication
applications. It is easy to use with
the help of pins on it. Provides
communication at 2.4GHz
frequency. The indoor area has a
communication distance of about 10
meters.
Figure-IV Bluetooth Serial Module

9.
In order to be able to study the design and
the planned system, a new mine structure
was uncovered without much change in
the mines. The mine is equipped with a
bluetooth serial module in boxes made of
stainless steel every five meters. In order
to exchange data, Arduino-Nano has
installed necessary codes using C and C ++
language.

10.
Figure-V Mine design
In mine design, The data from gas sensors and
pulse sensors located on the bracelet designed
for the miner are transferred from bluetooth in
the wrist strap to bluetooths placed every five
meters to the mine ceiling. These bluetooth
devices transfer the data to distributors located
every 30 meters on the mine ceiling. The
distributors transfer the received data to the
data processing center. Data is transferred
instantaneously on the follow-up panel in the
data processing center. The data coming from
this panel are examined and evaluated by the
staff. If the pulse of the madder falls, the gases in
the environment are raised above the specified
ratios, and the emergency button is pressed, the
background of the program in the data
processing center turns red and an "Emergency"
warning is displayed. Observations of such a
situation will result in the implementation of the
necessary emergency protocols. At the time of a
dent, the location of the miner is determined by
determining which floor and where the miner
data comes from the Bluetooth, and the search

11.
It is understood that the data coming
to the data processing center that the
miner's wristband is working on. The
transmission of the pulse, carbon
monoxide, methane and position data
of the miner is provided by the
communication between the
wristbands and the bluetooths on the
pan. When any of the miners that
appear in the program are selected,
the data of the selected miner will be
displayed in graphical form in the
program at the data processing
center.

12.
Experiment Part of the Project:
The school, which is used as an
alternative mine environment, consists of
of 4 kats. On the 4th floor there is a data
data processing center. Ten students
selected from school students were
distributed to different areas of the
school, and each person selected for the
the experiment was wearing a wristband.

methane and carbon monoxide sensors
sensors on the wrist has been transferred
transferred to the data processing center
center via the established system. As
experienced in the experiment, the data

As seen from the experiments, the prototype of the device and the inside of
the mine are instantly controlled at the data processing center of the mine's
pulse and position information. The transmitted data was evaluated by the
staff at the data processing center.
In the event of an emergency, the necessary emergency procedures were
carried out, the fans were operated automatically and the necessary actions
were instantly implemented via personnel via M-MATEKS.

15.
In the literature study, it is seen that there are few projects about this
sector. These projects have been understood from the wreckage that some
parts are very costly and the other parts are useless.
Therefore, M-MATEKS, which is inexpensive, sensitive, programmed and
feature-rich with its cost, is going to prevent the continuous mining
accidents in the world.

16.
Also;
 M-MATEKS can work with other systems at the moment of dent.
 In an unlikely event, the fans will work to reduce the dangerous gas
concentration in the environment.
 The data is processed automatically in the data processing center.
 All transactions are made with BlueToths and wireless communication
is provided.
With the support to be given, it is aimed that the project has a more
aesthetic structure, its application and dissemination in the mines.

17.
 Experiments can not be performed due to lack of suitable environment,
real environment of the mine can be done if the system is applied in real
mine.
 Further experimentation can increase the sensitivity level of the system.
 The wristband can be made more functional by adding sensors other than
carbon monoxide, methane sensor, and a smaller design can be made.
 Instead of putting too much bluetooth on the ceiling of the mine, the
shooting area could be wider NRF, Bluetooth 4.0, Xbee module, but
Bluetooth 2.0 was used in the project because the cost is at least when
Bluetooth 2.0 is used.
