Description
Technical field
The present invention relates to a kind of emergency advance warning system, storehouse numerical simulation of especially a kind of mine tailing and on-line monitoring integrated emergency early warning system.
Background technology
Domestic mine tailing storehouse water catchment area is generally all less than 10km
2, the overwhelming majority is less than 3km
2, there are not meteorology and discharge site when so little water catchment area designs in the mine tailing storehouse, this just causes two problems: do not have reliable meteorological hydrologic data when 1) designing in the mine tailing storehouse, can only calculate local hydrological calculation handbook by looking into.After the mine tailing storehouse is built up and come into operation, do not have the meteorological hydrologic data of reservoir area actual measurement to verify whether the data when designing originally is reasonable yet, whether need adjustment.2) the mine tailing storehouse does not have meteorological hydrologic forecast accurately when operation.Current meteorological hydrologic forecast all is to utilize the weather forecast data of province, the issue of city-level observatory to manage the mine tailing storehouse; But because mine tailing storehouse water catchment area is little; The formation flood peak lasts weak point, reservoir capacity for flood control is little, is prone to cause have a big risk in the operational process of mine tailing storehouse, and this forecast precision not enough; More frequent early warning occurs, cause anxiety and fear for the local government and the people; Do not have early warning to arrive, come temporarily when extreme meteorological disaster, mine management personnel, local government and the people are caught unprepared, and cause great life and property loss.
Because historical reasons; The monitoring in the mine tailing storehouse that metal mine has come into operation is in the situation that falls behind very much, and mainly show: 1) mine tailing Kuku district seldom has meteorological hydrometric station: can't obtain the flood achievement the when firsthand information comes verification to design originally more really like this and carry out meteorological hydrologic forecast; 2) the simple and crude backwardness of monitoring instrument: the dam body displacement observation is adopted and is buried precast concrete pile underground, with total powerstation or transit observation; Saturation observation is adopted boring to bury floral tube underground and is surveyed water level with tape measure; Water level is used on the structures that drain off floodwaters and draws water-level measuring post and observe in the storehouse.Like this, sensitivity and precision all are difficult to guarantee.3) manual measurement, manual work report: the storehouse safety management of existing mine tailing mainly is to lean on manual patrol, manual measurement, manual work to report the observation achievement, causes that personal error is big, poor reliability, effective poor.Particularly under extreme weather conditions; The concentrated period of dangerous situation takes place in the mine tailing storehouse often; Only depend on the data of manual patrol, manual measurement can not accurately and timely reflect the real time status in mine tailing storehouse effectively; The dangerous matter sources that occurs can not in time be found and notice reporting, delays the best opportunity of handling mine tailing storehouse dangerous situation.The monitoring system in mine tailing storehouse seriously lags behind society to environment and safe requirement at present.
Even if realized on-line monitoring, but also not the complete decision system of a cover for the safe operation of mine tailing storehouse.Reason is, as confluxing of the little water catchment area of this spy in mine tailing storehouse lasting very short (about 1 hour), in case when running into heavy showers, as not accomplishing advanced prediction, just can not stay time enough for emergency processing.
Summary of the invention
The objective of the invention is to a whole set of complete early warning system, and this cover system is introduced in the weather forecast that will become more meticulous first to the mine tailing storehouse.
Technical scheme of the present invention is: storehouse numerical simulation of a kind of mine tailing and on-line monitoring integrated emergency early warning system; This emergency advance warning system relies on provincial meteorological observatory; Through setting up the weather station in mine tailing Kuku district; Set up the meteorological hydrology of the small watershed monitoring station net in mine tailing storehouse; Adopt small watershed become more meticulous the weather forecast system with set up meteorological hydrology forecasting model, the quantitative precipitation estimating forecast that became more meticulous in leading 72 hours, 24 hours, 12 hours, 6 hours, 3 hours is carried out in flood season in the mine tailing storehouse, draw mine tailing Kuku district quantity of precipitation-crest discharge, flood volume relation then in view of the above.
Through mine tailing Kuku district 1:500～1:1000 topomap (containing the whole water catchment areas in mine tailing storehouse), draw the reservoir capacity for flood control under the different crest elevations of tailing dam, set up the relation between tailing dam crest elevation-extreme high water-reservoir capacity for flood control three.Utilize computational fluid dynamics method and technology (CFD); Set up mine tailing Kuku water level-earial drainage model, reservoir level-percolation model, reservoir level-dam break model; Through the method that computer numerical is calculated and image shows, the coverage after realizing mine tailing storehouse discharge capacity numerical simulation and drawing dam break.
Through the mine tailing storehouse is set up from the ground to underground; Point, line, surface, three-dimensional automatic monitoring system realize water level in the storehouse, reservoir area rainfall amount, dam deformation amount, dam seepage line, dam body seepage flow, the real time on-line monitoring of doing key indexs such as beach length and the monitoring of reservoir area video.The data that monitoring in real time obtains are come verification and revised leading meteorological hydrology forecast information and numerical evaluation model, accomplish advanced early warning.Above-mentioned meteorological hydrology forecast system-mine tailing storehouse numerical simulation technology-on-line monitoring system is coupled and comprehensive integration, forms complete mine tailing storehouse comprehensive emergency advance warning system.
The invention has the advantages that: the present invention combines meteorological department to set up mine tailing storehouse become more meticulous meteorological hydrology forecast system and meteorological hydrological model; Use for reference the comparatively ripe dam monitoring technology of hydraulic department development and set up on-line monitoring management system and the monitor and early warning system that satisfies mine tailing storehouse monitoring characteristics; Utilize the computational fluid dynamics technology to set up general mine tailing Kuku water level-earial drainage, seepage flow, dam break model, above three is merged, form the emergent decision service system of complete mine tailing storehouse three-dimensional visible model.The leading weather forecast information that becomes more meticulous has been arranged, can shift to an earlier date anticipation mine tailing storehouse running status in conjunction with mine tailing storehouse rainfall-runoff model, runoff-reservoir level model, reservoir level-earial drainage, seepage flow, dam break model, for emergency processing stays the enough time; Through water level and dam body running status, verification and the achievement of revising mine tailing storehouse advanced prediction conversely in the reservoir area rainfall under the on-line monitoring system monitoring real-time status, the storehouse.This three is expressed through the quicklook of three-dimensional visualization model, can be enterprise and local government and forecast in advance, in time grasp and calm decision-making provides technical support.
