The inventive coal and gas outburst synthesized early warning system and early warning method can perform centralized management and comprehensive analysis of the geological structure, coal seam occurrence, gas occurrence, mining production, daily forecast indicators, outburst forecast, gas emission and other security information that originally scatter in various functional sectionsof coal mine on the geographical information system GIS platform, integrates the existing resources, improves the accuracy of early warning, so that the early warning is both real-time and forward-lo oking, and can effectively prevent the occurrence of coal and gas outburst in coal mine.
Description
Technical field
The present invention relates to the safety of coal mines technical field, be specifically related to the early warning system and the method for early warning of the outstanding disaster of a kind of down-hole coal and gas.
Background technology
Coal and gas outstanding (hereinafter to be referred as " giving prominence to ") are a kind of extremely complicated dynamic phenomenons that occurs under the coal mine; it can be in a short period of time; by coal and rock to tunnel or stope dish out a large amount of coal petrographys and gas; produce as push over mine car, destroy support, cause dynamic effect such as the distinguished and admirable reverse in tunnel; destroy down-hole facilities and equipment and ventilation system through regular meeting; and cause coal to bury casualty accidents such as personnel, gas asphyxiation, gas explosion easily, bring serious threat to the colliery safety in production.China is one of the most serious country of outstanding in the world disaster, projecting mine is many, the distribution region is wide, outstanding accident is many, intensity is big, the number of casualties is many, so the control of outstanding disaster is coal industry scientific worker and safety management person's a primary study content always.Research and practice through decades, China has formed a cover collection outburst hazard prediction, outburst prevention measures, outburst prevention measures validity check, safety prevention measure in interior " quaternity " comprehensive outburst control measure technical system, implementation by this cover protrusion-dispelling system, instructed the control of outstanding disaster effectively, but, because a variety of causes still can not block up the generation of giving prominence to disaster extremely at present fully.
The outburst hazard prediction is the important step of outstanding integrated control system, at present, each projecting mine of China is the mode by drilling mainly, measures the outburst hazard of zone, coal seam or work plane, takes outburst prevention measures to eliminate outburst danger at adventurous zone or work plane then.But present outburst prediction method and index exist following main not enough: 1. Chang Yong outburst prediction method be in time static, spatially be discontinuous, still can not predict outburst hazard in real-time continuous ground; 2. outburst hazard is to determine according to the item forecast desired value of measuring, but, mostly prediction index commonly used is to influence with the reflection of part indirectly the three big factors (physico-mechanical properties of stress, gas bearing situation and coal that coal body is suffered) of outburst hazard, and objectively also there is certain limitation in index; 3. mostly common forecasting method is the state of prediction outburst hazard, and does not consider to be unfavorable for dangerous development trend taking measures in advance; 4. common forecasting method is general only simple definite according to the size of testing index, and dynamically do not take all factors into consideration the gush out situation of change etc. of situation, outstanding omen situation, daily outburst hazard prediction index of coalbed gas geology situation around the work plane, exploitation deployment scenarios, protrusion-dispelling technical measures implementation status, face gas, the outburst prediction accuracy rate is still waiting to improve; 5. predicting the outcome, it is dangerous and be safe from danger two kinds generally to be divided into, and when danger, still can not provide danger classes.
At present, the most coal and gas outburst mines of China have all been installed coal mine safety monitoring system (producing comprehensive monitoring system etc. as KJ90 moulded coal ore deposit safety comprehensive monitoring system, KJ101 type Mine Monitoring and Control System, KJ95 Coalmine's Monitoring and Controlling System, KJF2000 mine safety), but, outburst prediction is not nearly all analysed in depth, realized to monitor data, and the effect of monitoring system also is not fully exerted.Development along with informationization technology, the colliery LAN of oneself has all been set up in most collieries, can realize sharing of part security information, but, what realization was shared is the managerial information of colliery routine safety mostly, unusual shortcoming also aspect specialized informations such as coal and gas outburst prevention treatment shared is unfavorable for analysis-by-synthesis and the early warning given prominence to.Aspect the figure drafting of ore deposit, most mines have all adopted the CAD drawing, but, the ore deposit figure of this electronization can't satisfy digitized needs, at present, some software companys have developed based on the ore deposit figure drawing system of geographical information system (GIS) and at the part mine and have applied, and for the digitlization and the information work of mine are laid a good foundation, also provide condition for the outstanding early warning technology research and development of coal and gas.
At present, China does not still set up the outstanding pre-alarming system of coal and gas, and the research of giving prominence to method for early warning has also just been begun starting.
