| titleOfInvention | Mineralization ecological protective coal mining method utilizing CO2 waste gas |
| abstract | The invention discloses a method for mineralizing and utilizing CO 2 The waste gas ecological protective coal mining method is suitable for underground coal mine. Determining filling mining critical key parameters required by stability of mining overburden seepage isolation zones of a stope, constructing sealing walls at two ends of a mining space along with the advance of a working face to seal the mined area, and then pouring CO into the sealed area 2 The mineralized filling material CFBF carries out mining and filling along with the goaf, and supports for the goaf after the CFBF is solidified are guaranteed; the CFBF is prepared by using gangue, coal ash and mine sewage in a mining area and assisting cement and an alkaline silicon-based additive, thereby not only ensuring the formation of a mining overburden seepage isolation zone, but also being capable of carrying out continuous CFBF filling, and finally realizing CO 2 Replacement with coal. Simple operation, reliable result and capability of realizing CO 2 Greatly improves the extraction rate of coal resources on the premise of mineralization and solid waste material treatment. |
