Roadway is a necessary passage for coal mining.
Undertake transportation、Ventilation、Drainage and other functions
Coal cannot be mined without roadways.
A long time
Coal Mine Tunneling Equipment in China
It means digging but not supporting
The roadway cannot be formed at one times
“Foreign monk”Not acclimatized
Growing demand for energy
Coexistence of market and opportunity
Research and development personnel of China Railway Construction Heavy Industry
Bear heavy burdens bravely、Face the difficulties
Developed suitable for China's coal mine roadway construction.
Complete set of equipment for quick digging and anchoring
In order to solve the imbalance of coal mining
Compete on the same stage to solveA worldwide problem
“Anchor digging synchronization”
The most advanced imported digging and anchoring machine
It can't be achieved“Anchor digging synchronization”
How to overcome this worldwide problem?
Time matching is key.
In more than six weeks.
R & D personnel test with stopwatches every day.
Tested over 100 times
Compare thousands of sets of data
Finally, we got the perfect matching time.
At the same time
In order to let“Coal Sea Dragon”
It can eat better.“Ugin”
The R & D personnel adopt the horizontal shaft type telescopic roller
Designed a hard mouth for it“ Tooth ”
Match the width of the drum to the width of the roadway
Adapt to different types of roadway excavation
“A sharp mouth”And“Flexible arms”
Let“Coal Sea Dragon”Realize synchronous operation of digging and anchoring
And that labor intensity is greatly reduce.
And improves the safety of coal mine tunneling.
Let China's Coal Mine Roadway Excavation
Mechanization has been realized
Coal Mine Driving“The little security guard”
400 meters underground，Everything is unknown.
How to predict the geological conditions ahead
And that construction safety is ensure
It has become another difficult problem that needs to be overcome urgently.
One advance drilling machine
By connecting the drill pipe section by section
Drilling depth of more than 100 meters in advance
Find problems ahead of time、Take measures
To ensure the safety of underground operators and equipment.
A set of dedusting device
Through semi-closed dedusting system
Circulate the airflow at the heading fact
Address the potential risk of dust explosion
2016
The first complete set of rapid anchor digging equipment developed by China Railway Construction Heavy Industry Co., Ltd.
First application to
Sunyingcha No.1 Mine, Dianta Town, Shenmu City, Shaanxi Province
Achieve the highest monthly footage of 1204 meters
Innovation and upgrading of core equipment
Promoting the progress of the industry
Changed the traditional operation
Nearly a hundred people crowded into the narrow space underground.
The labor intensity is high、Poor operating environment
A difficult situation
Fast“Transformation and upgrading”Meet new challenges
In the face of large cross-section roadway and poor geological conditions.
“Coal Sea Dragon”How to proceed“Upgrading”
The first is to solve the working area.
The pulverized coal is large
Flammable、Explosive problem
R & D personnel through simulation analysis
A special foam dedusting system is designed.
While ensuring the strength of the cutting head,
Solved effectively
Noise of negative-pressure dedusting fan
Poor dust removal effect
In addition
The conveying system is often stuck by large coal blocks.
Resulting in poor operation
Seriously affect the construction progress
The R & D personnel designed
Three-channel double-shaft Crusher
The problem of coal block stagnation was successfully solved.
At the same time
The R & D staff also upgraded.
Turn the transport bridge、Cutting drum, etc
Important components
After 103 days of digging
Complete set of equipment for quick digging and anchoring
Precise penetration of 5992 meters of roadway half a month ahead of schedule
And created the world's first
Large section roadway of 10m large mining height working face
The world record of 1750 meters per month
“An intelligent brain”How to build an unmanned mine
In order to reduce the labor intensity of construction personnel
Let“Coal Sea Dragon”Better
Ensuring safety and efficiency of coal mine construction
The R & D personnel proposed
Intelligent coal mine construction、Unmanned
The device is given multiple items“Superpowers”
Underground in a sea of coal
You can't see your hand
In order to let“Coal Sea Corps”Capable of autonomous operation
You have to let it have a pair.“Night vision”
Research and development personnel of China Railway Construction Heavy Industry
According to the experience of tunnel construction
DevelopedUWBContinuous positioning mechanism of
Realize continuous autonomous tunneling
At the same time
Through the radar correction system
Achieve automatic walking of complete set of equipment for rapid digging and anchoring
And then
The R & D personnel decided to give the equipment
Carry out a comprehensive“Upgrade”
Let the complete set of intelligent digging anchor equipment have“An intelligent brain”
Realize remote control and one-button start on the ground
2023
Developed by China Railway Construction Heavy Industries
The world's first complete set of super-large section intelligent fast digging equipment
At Caojiatan Mining Company
It has created a super-large section roadway excavation.
Monthly footage of 3008 meters
Work efficiency reaches 3 to 5 times of traditional tunneling equipment
Set up a survey、Dig、Branch、Transport in one
The tunneling is realized、Anchor protection synchronous operation
And that tunnel speed of the equipment is improved.
It has solved the problem of mining imbalance that has plagued coal mines for a long time.
Speed up the development of coal mine intellectualization
Successfully build mine construction 5.Age 0
