Description
Technical field
The present invention relates to mine gas prevention and control field more particularly to a kind of pre- police of compound coal rock gas dynamic disaster
Method.
Background technique
In terms of energy demand angle, China will not change in the energy pattern short time based on coal, coal specific gravity compared with
It will remain in 50% or so in long-time, and coal mining 95% or so is based on the pit mining of underground.Currently, coal mining is with every
The speed in 10 ~ 20m of year extends to deep, and deep mining has been increasingly becoming normality in the central and east, and brings new coal petrography gas
Dynamic disaster problem.Mine coal rock gas dynamic disaster most typical two kinds of forms of expression in China's are coal and gas prominent and impact
Ground pressure, but central and east coal seam containing gas dynamic disaster shows a kind of dual dynamic with Burst Tendency and outburst hazard
Learn characteristic, bump single by superficial part, independent or coal and gas prominent be changed into it is compound, the various dynamic disasters of coal petrography it
Between interaction reinforce, coal rock gas dynamic disaster feature becomes complicated and multiplicity, and it is main, new to have become coal mine one kind
The safety hazard of type.Durings breeding, exciting, develop etc., many factors are interweaved compound coal rock gas dynamic disaster,
It mutually induces, strengthen, so that the condition occurred is lower, disaster intensity is bigger, causes calamity degree more serious, so that genesis mechanism is more
Complexity, prediction, early warning and prevention and treatment are more difficult.But compound coal rock gas dynamic disaster early warning prevention aspect has only carried out just at present
The early warning prevention technique using coal and gas prominent and bump of step research or machinery, not yet forms oneself independent early warning

Range a processed, pitch of holes b, in advance away from c, compared by actual implementation result parameter with design parameter, carry out early warning；
S23: collection is related to the reasonable digging deployment decision in disaster region, comprehensive preventive health measures, each ring of Local synthesis control measure
The habitual error behavior of section personnel, establishes database, establishes warning index；
By being related to the reasonable digging deployment decision in disaster region, comprehensive preventive health measures, Local synthesis control measure links people
The habitual error behavior of member, establishes database, and foundation is, no execution warning index, and warning index is whether digging deployment closes
Reason, whether comprehensive preventive health measures executes, whether Local provisions execute, and index value is 0 or 1, and such as not no with legitimate result, index is
0, then carry out early warning；
S24: from disaster occur objective danger, precautionary measures defect and management defect building warning data storehouse, warning index and
Sentence knowledge analysis mathematical model, critical value, carries out compound coal rock gas dynamic disaster comprehensive pre-warning；Refer to according to objective danger
Mark, precautionary measures defect index and any one the compound coal rock gas dynamic disaster early warning of progress for managing defect index；
Implement software platform, sensor has:
Basic data system 1: 1. GIS-Geographic Information System, realizes mine digital management；2., storage is related for early warning large database concept
Warning index information needed data；Coal mine safety monitoring system data collection system is 3., dense for gas in collection monitoring system
Degree evidence；
Compound disaster alarm index, which is sentenced, knows analysis system 2: 4., timely update management ground for geology, digging dynamic management system
Matter, digging situation delta data, provide foundation for objective danger index；Stress dynamic analysis system 5., as digging changes,
It timely updates and manages mine stress distribution change information, provide foundation for objective danger index；The daily early warning system of monitoring system
6., relative stress, gas bearing capacity and the Coal Pore Structure index that timely intelligent updating management variation ofgas density is reflected are objective to system
It sees risk index and foundation is provided；Comprehensive preventive health measures management system 7., the management prognostic that timely updates, control measure performance
Data provide foundation for objective danger and control measure defect index；8., timely update administrative staff's behavior analysis system pipe
Human behavior data are managed, provide foundation for management risk index；Comprehensive objective danger, control measure defect and management risk refer to
Mark carries out compound disaster prewarning and forecasting；
Underground various parameters determination sensor provides data acquisition 3, monitoring system sensor；
Ground early-warning server 4, for storing warning information data；
S25: early warning result release management system 5 issues alarming result by network, mobile phone；
Using Internet technology, by compound coal rock gas dynamic disaster early warning technology, from compound disaster objective danger,
Disaster prewarning and forecasting is carried out in terms of control measure defect and management risk three, realizes the comprehensive process control of disaster, and is led to
Early warning based data service device, warning index are sentenced and know analysis system and coal mine peace by the compound disaster early warning system for crossing invention
Full monitoring system connection realizes the intelligent early-warning of compound disaster and the network of result, mobile phone publication.
