Description
Technical field
This utility model relates to a kind of down-hole based on image and coal-winning machine monitoring device floods warning system, and this system relates to image
Pattern recognition with the field such as communicate.
Background technology
Coal is China's main energy sources, accounts for primary energy 70%.Coal industry is high risk industries, gas, floods, fire,
The accident such as top board, coal dust annoyings Safety of Coal Mine Production.In China's coal-mine generation severe and great casualty, to mine during mine water disaster
The natural disaster that hazardness is bigger, calculates with the number that coal mining accident is dead, and water damage accident accounts for 15.72%, be only second to gas and
Roof accident, occupies the 3rd, and after mine generation floods accident, its harm includes:
1, destroy by rush of water tunnel, pile things on, flood and closure personnel.
2, with gushing water, have substantial amounts of coal slime and rock alluvial tunnel, cause difficulty to personnel escape.
3, damage equipment.Down-hole electrical equipment, after cable is immersed in water, its insulating capacity declines rapidly, to the transport of down-hole, leads to
Wind, draining etc. cause difficulty, make the probability of surviving fleeing from personnel the most in time reduce.
4, gush out substantial amounts of toxic and harmful, make the conditions of existence's environment fleeing from personnel the most in time more deteriorate.
In sum, mine water disaster is the disaster that colliery is serious, in coal production the warning to mine water disaster must accomplish and
Time accurate.At present floods early warning based on hydrology detection prevention, the observation of underground for probing water, tendency phenomenon and, the hydrology detects and well
Test water can prevent down-hole floods accident, but owing to there is likely to be that hydrologic regime is complicated, it is improper to design, take effective measures, managing
Reason is not good at the reasons such as the thought paralysis with people, and hydrology detection and underground for probing water can not be entirely prevented from the generation of gushing water, more can not
The down-hole gushing water of burst is reported to the police；Tendency phenomenon is observed based on artificial micro-judgment, there is bigger subjective factors.
At present for on-the-spot water inrush accident, rely primarily on the artificial warning of Field Force, but when gushing water occurred in the unattended time
Or region, or Field Force flees from hastily and fails initiative alarming, and control room just cannot obtain timely and gushing water occurs
Information, it is impossible to notice down-hole relevant staff in time, so that water inrush accident can not be taken emergency measures in time, Yi Zao
Become water damage out of control and casualties.Coal-face is the region that down-hole easily occurs water inrush accident, causes for effectively reducing floods
Mine property loss and casualties, need new coal-face down-hole floods warning system, can the very first time exactly
Coal-face gushing water is reported to the police, for not in the disaster relief and the escape occurring on-the-spot other region personnel in the pit to strive for preciousness
Time.
