The accidents such as calamity, top board, coal dust annoying Safety of Coal Mine Production.In China's coal-mine generation severe and great casualty, to ore deposit during mine water disaster
The natural disaster that well hazardness is bigger, calculates with the number that coal mining accident is dead, and water damage accident accounts for 15.72%, is only second to gas
And roof accident, occupying 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, 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, and in coal production, the warning to mine water disaster must be done
To promptly and accurately.At present floods early warning based on hydrology detection prevention, the observation of underground for probing water, tendency phenomenon and, hydrology detection with
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, 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.Mesh
Before for on-the-spot water inrush accident, rely primarily on the artificial warning of Field Force, but occur in the unattended time when gushing water or
Region, or Field Force flees from hastily and fails initiative alarming, and control room just cannot obtain the letter that gushing water occurs timely
Breath, it is impossible to notice down-hole relevant staff in time, so that can not take emergency measures water inrush accident in time, easily causes water
Out of control and the casualties of evil.For effectively reducing mine property loss and the casualties that floods cause, need new underground coal mine
Floods warning system, can report to the police to underground coal mine gushing water the very first time exactly, for not there is not other on-the-spot region
Personnel in the pit strives for the disaster relief and the escape time of preciousness.
