Description
Technical field
The utility model relates to a kind of monitoring device of mined-out area hazard index, particularly about a kind of comprehensive continuous monitoring device of mined-out area hazard index.
Background technology
At present, the instrument and equipment of domestic and international INTEGRATED SIGHT gas componant and concentration, temperature and ore deposit pressure does not also have, and main observation procedure is that various index is observed respectively.1) goaf gas componant and concentration observation.Goaf gas componant and concentration observation, mainly by arranging sampled point in goaf, being buried sampling sebific duct underground and being carried out.Sampling sebific duct is routed to air intake workplace, return airway and coal face by sampled point, regularly extracts gas sample to (general every day gets a sample) in bladders, takes composition and the concentration of ground chromatographic gas to.This kind of method is comparatively large by the impact of manual operation, to survey data often inaccurate.Another kind of goaf gas componant and concentration observation instrument are mine tube bundle monitoring systems, and it is directly connected with monitoring system by buried beam tube, monitor the change of each measuring point gas componant and concentration in goaf continuously.The Tube Bundle Monitoring System that domestic colliery is commonly used is KSS-2100 colliery natural fire Tube Bundle Monitoring System and JSG-8 type underground fire Tube Bundle Monitoring System, also has the SG-2003 type mine spontaneous fire disaster Tube Bundle Monitoring System that Beijing thing analytical instrument company produces in addition.The gaseous species of KSS-2100 system and SG-2003 system monitoring is many, and precision is high, but gas circuit is long, system complex; JSG-8 system architecture is simple, and pipeline is short, and pumping resistance is little, and be convenient to and mine safety monitoring system networking, but the gaseous species of monitoring is few, precision is low, and sensor needs regular calibration.
2) goaf temperature observation.Underground goaf temp measuring method mainly contains two kinds, and one utilizes infrared thermometer thermometric, is mainly used in the daily temperature detection of mine.Because infrared thermometer can only detecting object surface temperature, and have no occluder in the middle of requiring, so more applicable for the surface temperature detecting rib, coal column is piled with float coal, be not suitable for the inner temperature detection in loose coal inside or goaf.Another kind utilizes temperature sensor thermometric, and conventional temperature sensor has thermal resistance, thermopair, semiconductor temperature element and semiconductor temperature sensor etc.The principle of work of thermal resistance and thermopair is thermoelectric effect, and its detection method buries temperature sensor underground in the region that spontaneous fire probability is higher, the temperature of remote continuous detecting loose coal.Thermopair, temperature detecting resistance and semiconductor temperature sensor etc. are widely used because it is cheap, it is simple, easy to operate to test.But owing to installing, maintenance workload is large, particularly pops one's head in, goes between and very easily destroy, cause result of use undesirable.
3) goaf pressure observation.Based on the pressure observation in coal face and tunnel in the pressure observation of colliery, observation instrument has pillar dynamometer, roof dynamic monitor table and separation indicator etc.Because these instruments are all specialized designs for the pressure observation of support and top board, they can not be applied in the pressure observation in goaf.
In sum, at goaf gas componant and concentration observation, existing comparatively widely used monitoring device in the temperature observation of goaf, not a kind of special purpose device in the pressure observation of goaf.Meanwhile, above monitoring device can only be observed single aspect, does not have a kind of device, can carry out comprehensive continuous print monitoring to mined-out area hazard index.
