The beneficial effect of the utility model compared to the prior art is:
(1) since neutron has stronger penetration power, traditional microseism (sound emission) and electromagnetism are replaced using neutron irradiation
Radiotechnology, monitoring range is wider, and applicability is stronger；
(2) digital monitoring is used, by monitoring system terminal real-time perfoming neutron irradiation dosage acquisition, avoids error
While accumulative, keep monitoring safety higher；
(3) it dynamic acquisition can be gone forward side by side in real time by the coal petrography internal rupture precursor information within the scope of back production, driving disturbing influence
Row data processing and analysis, thin sight deformation behaviour macro to coal and rock are monitored judge, more comprehensively understand and grasp back production, driving
Coal and rock dynamic deformation process in perturbing area；
(4) it is compared, entire monitoring region is divided, and to danger area by monitoring data and the analysis of Alert Standard value
Domain carries out grading forewarning system, escorts for Safety of Coal Mine Production from the coal petrographys unstability dynamic disaster such as rock burst, bump.
In conclusion the utility model is designed reasonably, strong operability can be the case where considering various complicated geological environments
Lower effectively realization underground coal Instability of Rock Body dynamic disaster sentences knowledge early warning, and more dynamic realtime, accurate safety, science is convenient.
