Description
Technical field
The invention belongs to technical field of mine safety, are related to a kind of coal mine gas disaster monitoring early-warning system and the pre- police
Method.
Background technique
In china natural resources preservation " rich coal, oil-poor, few gas ", coal as China's main energy sources status following very long one
It is difficult to change in the section time, 50% or more, and country's " energy Long-and Medium-term Development rule will be accounted in China's primary energy structure
Draw outline (2004-2020) " in it has been determined that it is Chinese will " adhere to based on coal, centered on electric power, oil gas and new energy
The energy strategy of source development in an all-round way ", but the complexity of China's coalbed-forming and environmental effect determines Coal Mine Disasters objectively
Just extremely serious, wherein Gas Disaster is especially prominent, is the chief threat of China's mine safety production.China is by decades
Research and practice, have obtained significant progress in terms of coal mine gas diaster prevention and control technology and equipment, form gas control " first
Adopted after pumping, monitoring, with wind fixed output quota " 12 word policies and " ventilation is reliable, extraction is up to standard, effective monitoring, management in place "
16 word work systems, especially formd in terms of preventing and treating coal and gas prominent it is a set of with " based on region ' quaternity ',
Supplemented by part ' quaternity ' " " two quaternities " Synthetical control system, while researching and developing and having promoted and applied gas drainage
Monitoring, gas-monitoring, drilling construction monitoring, ore pressure monitor, personnel location system, prominent parameter prediction instrument, ventilation parameter are comprehensive
A series of monitorings such as analyzer, detection system and equipment play great function for Gas Disaster prevention and treatment.But due to gas calamity
Evil influence factor is numerous, and mechanism is complicated, and continues to increase due to adopting deep gradually increase with mining rate, Gas Disaster
It is difficult to administer further, situation of production is still severe.
Prediction and warning is the primary link of Gas Disaster prevention and treatment, and mine takes a small number of Static State Indexes (such as prominent mostly at present
Prediction mainly uses construction, gas, soft layering, K out1, q, coal powder quantity of bore etc.) carry out danger forecasting, that there are this indexs is single, when
Between it is upper non-dynamic, spatially discontinuous the deficiencies of, hidden danger information analysis it is deeply also not prompt enough the problems such as, cause prediction quasi-
True property is not high；Although original Coalmine's Monitoring and Controlling System plays to a certain extent simultaneously reduces the effect that gas accident occurs
Fruit, but generally speaking there is also many immature, incomplete places, monitoring system can only simply turn initial data
It changes, store, show and prints, data resource excavates, analysis depth is inadequate, cannot find disaster hidden danger in time, entire to be
The warning function of system is not strong, essentially stays at alarm rather than in such a level of early warning；Furthermore it manages not in place
It is the multiple key factor of gas accident, and relies primarily on the management that artificial supervision checks extensive style at present, is not able to satisfy management
Requirement in place has a certain gap with fining, procedural advanced management theory.Therefore it is numerous to comprehensively consider Gas Disaster
Influence factor, carries out comprehensive real-time analysis to security risk and early warning is the development trend of coal mine gas diaster prevention and control, is based on
