Ordovician Limestone Water Inrush Governance Technology Of Fengfeng Mining Area

Fengfeng Mining Area is an important coal production bases in China,which is a typical mine flood.Compared with other mines in geological and hydrogeological conditions,floor water damage problem complexity,and the degree of threat by floor water damage,it is one of the most complex and severe water situation in the region control.Especially,with the mining depth increases,the mine floor Ordovician limestone water hazard problem become more prominent.At the same time threaten of the safety by floor Ordovician limestone water disasters in mine production is also growing.The past 10 years,Fengfeng Mining Area has happened many times in Ordovician limestone water disasters,which gave each enterprise caused huge economic losses.Thesis within studying the Fengfeng mine geological and hydrogeological conditions of the summed up the entire mining area of the main geological and hydrogeological characteristics;The recent passage of Ordovician limestone mine water inrush disaster-prone typical cause and analysis of water inrush disasters lay the foundation for the study of Ordovician limestone mine water.By plugging water inrush occurred under different environmental analysis and research,it proposed to "Wai point reinforcements" for the next move of the key technologies of water environment water inrush control technology to move aggregate filling duration of the construction technology pros and cons of water conditions over the water channel filling aggregate technology,porous parallel double liquid grouting technology as the key technology of collapse-in water inrush control technology,exploration technology to water inrush channel,four in one comprehensive guide subsided column sealing technology,group artificial joint grouting hole intermittent pre-press technology as the key technology unloaded large mining hidden deep under water inrush from collapse column water treatment technology by combining with specific examples mining verified.On this basis,paper summed up a set applies to the whole mining area of Ordovician limestone water treatment technology integration for the prevention and treatment of mine water to carry out the work,that ensure the maximum degree to avoid or mitigate the impact to provide a reference for the production of water inrush.While similar conditions of the mine water damage and rapid treatment also has important guiding significance.
