Description
Technical field
The utility model is related to a kind of based on ranging and the coal working face floods alarm system to test the speed, which is related to surpassing
The fields such as sound wave, tellurometer survey, velocity measuring technique and communication.
Background technology
Coal is China's main energy sources, accounts for about primary energy 70%.Coal industry is high risk industries, gas, floods, fire
The accidents such as calamity, top plate, coal dust annoying Safety of Coal Mine Production.China's coal-mine occurs in severe and great casualty, to mine when mine water disaster
The larger natural calamity of well harmfulness, is calculated with the number of coal mining accident death, and water damage accident accounts for 15.72%, is only second to gas
And roof accident, third is occupied, after floods accident occurs for mine, harm includes：
1, it destroys by rush of water tunnel, pile things on floods and block personnel.
2, with gushing water, a large amount of coal slime and rock siltation tunnel is had, difficulty is caused to personnel escape.
3, equipment is damaged.Underground electric appliance, after cable is immersed in water, insulating capacity declines rapidly, to the transporting of underground, leads to
Wind, draining etc. cause difficulty, make the probability reduction of surviving for not fleeing from personnel in time.
4, gush out a large amount of toxic and harmful gas, the life condition environment for not fleeing from personnel in time is made more to deteriorate.
In conclusion mine water disaster is the serious disaster of coal mine, the alarm of mine water disaster must be done in coal production
To promptly and accurately.Floods early warning at present with the hydrology detection preventions, underground for probing water, tendency phenomenon observation and based on, the hydrology detection with
Underground for probing water can prevent underground floods accident, but it is complicated since there is likely to be hydrologic regimes, design is improper, takes effective measures, manages
Reason is not good at that with the reasons such as the thought of people paralysis, the hydrology detection generation of gushing water can not be entirely prevented with underground for probing water, can not
It alarms the underground gushing water of burst；The observation of tendency phenomenon is taking human as based on micro-judgment, and there are larger subjective factors.Mesh
It is preceding that the artificial alarm of Field Force relied primarily on for live water inrush accident, but when gushing water be happened at the unattended time or
Region or Field Force flee from and fail initiative alarming hastily, and control room just can not timely obtain the letter that gushing water has occurred
Breath, can not notify underground relevant staff, so that cannot in time take emergency measures to water inrush accident, easily cause water in time
The out of control and casualties of evil.Mine property loss and casualties caused by effectively reduce floods need new underground floods
Alarm method can at the first time accurately alarm to underground gushing water, for not in other region personnels in the pit that scene occurs
Strive for the valuable disaster relief and escape time.
