Description
Technical field
This utility model relates to a kind of colliery floods warning system monitored based on image and hydrographic data, and this system relates to the fields such as image steganalysis, communication and sensor.
Background technology
Coal is China's main energy sources, accounts for primary energy 70%.Coal industry is high risk industries, and the accident such as gas, floods, fire, top board, coal dust annoyings Safety of Coal Mine Production.In China's coal-mine generation severe and great casualty, natural disaster bigger to mine hazardness during mine water disaster, calculate with the number that coal mining accident is dead, water damage accident accounts for 15.72%, is only second to gas and roof accident, occupies the 3rd, 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, causes difficulty to the transport of down-hole, ventilation, draining etc., makes 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, and in coal production, the warning to mine water disaster must be accomplished promptly and accurately.At present floods early warning observe based on hydrology detection prevention, underground for probing water, tendency phenomenon and, hydrology detection and underground for probing 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, manage improperly and the reason such as thought paralysis of people, hydrology detection and underground for probing water can not be entirely prevented from the generation of gushing water, more can not report to the police the down-hole gushing water of burst；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 occurs in unattended time or region, or Field Force flees from hastily and fails initiative alarming, control room just cannot obtain the information that gushing water occurs timely, down-hole relevant staff cannot be notified in time, so that water inrush accident can not be taken emergency measures in time, easily cause that water damage is out of control and casualties.For effectively reducing mine property loss and the casualties that floods cause, need new underground coal mine floods warning system, exactly underground coal mine gushing water can be reported to the police the very first time, for not occurring on-the-spot other region personnel in the pit to strive for the disaster relief and the escape time of preciousness at gushing water.
