Technical field
The utility model relates to colliery safety-security area, is specially water source, the colliery recognition system based on DSP and LIF.
Background technology
China is one of country that producing coal amount is maximum in the world.More than 90% of raw coal total production belongs to pit mining.But China Mine Geological, hydrogeological condition are generally speaking very complicated, the coal reserves threatened by water damage accounts for 27% of proven reserves, and the coal reserves that only North China threatens by base plate piestic water is about 16,000,000,000 t.
Coal mine flood be emit with Gas Outburst, dust explosion, top board split, one of five large disasters that fire etc. is arranged side by side, its order of severity is only second to gas row second.For a long time, the country and people's lives and properties caused because of coal mine flood and economic loss are very heavy.Such as, on May 13 nineteen thirty-five, Shandong Zibo Beijing University well is because tunnel pick is to the distributed fault be communicated with river, and cause gushing water, maximum instantaneous water yield 648m3/min, 350 miners are wrecked, and mine stops production and scraps.Until 1978 after 43 years just recover shaft production; On June 2nd, 1984, there is the Water Inrush From Karstic Collapse Columns accident that the world digs up mine rarely seen in history in the Kai Luanfange village 2171 fully-mechanized mining working, maximal water*.inrush quality 2053m3/min, causes the Fan Ge village and periphery three pairs of mines thereof to be flooded very soon.For disaster relief complex ore, having assembled is that water prevention expert the most authoritative in global range and suction pump maximum are in the world speedily carried out rescue work at that time substantially.Surface grout injection shutoff project scale and scene are also unprecedented.Flood harnessing project and related work last nearly 1 year, and direct indirect economic loss is more than 500,000,000 yuan.
In addition, according to incompletely statistics, from more than 20 years so far eighties in last century, China has nearly 250 pairs of mines not had by water logging, dead nearly 9000 people, economic loss more than 350 hundred million yuans.Only there is all kinds of coal mine flood accident 1391 altogether, dead 5280 people between years 11 years nineteen ninety-five to 2005.Account for 7.6% of the dead sum of all kinds of coal mining accident, the wherein above water damage accident of 10 people 105, dead 1881 people.Nearly 21,000,000,000 yuan of economic loss.Particularly recent years, along with the change of mining conditions, all kinds of water damage accident frequency and death toll all gain momentum.
Whether normal operating conditions is in for coal production construction can be detected quickly and accurately, the utility model discloses a kind of more reliably, more effective, safer water source, the colliery recognition system based on DSP and LIF, can be real-time colliery water sample concentration be monitored, utilize LIF theoretical, draw the relation of solute concentration and laser fluorescence intensity in spectroscopic data research water bursting sources, water source type identification is carried out, for the early warning of mine water bursting disaster provides decision-making foundation by the characteristic spectrum of different gushing water water sample.
