Description
Technical field
The present invention relates to coal mining security monitoring field, be specifically related to ground subsidence method for early warning and technology in the progress of coal mining.
Background technology
Radon is the gaseous state radionuclide in the naturally radioactive decay series, and its decay constant is again a kind of not volatile radioactive substance.The zone of fracture that the ground subsidence process forms, for the migration of radon provides good passage, the radon in the stratum can be moved to the face of land under effects such as convection action, groundwater effect, microbubble effect, geothermal action, geostatic stress effect, tidal action, swabbing action, ground vapour effect, seepage effect.The development degree of zone of fracture can influence the migration level of radon to a certain extent in the stratum, specifically can be reflected at the earth radon information that measures in the surface soil.In progress of coal mining, collapsing the eve when the stratum, therefore inevitable energy measurement can use high-precision GPS difference location observation survey mark to the deformational displacement of gps coordinate position, can monitor the minor variations of settlement of stratum process.
One of energy that coal resources are extensively utilized by the mankind, there is a large amount of coal mining operations in the colliery in that China has over thousands of seat to differ in size.And in progress of coal mining, surface collapse is one of major Safety of present coal mining, and the rock stratum subsides in the progress of coal mining, badly influences the safety in production of coal mining industry.The colliery is that collection is artificial, the complication system of machinery, mining engineering, geological conditions and natural environment coexistence, and Fundamentals such as its catastrophe mechanism, approach are difficult to determine, factor state ambiguity by force, secure data is abundant inadequately, and accident rate is higher.The colliery that regular meeting the differs in size during China incident of caving in.Therefore, when carrying out coal mining, the work of surface collapse safe early warning seems particularly important.
