Prediction of the Adaptability of Using Continuous Extraction and Continuous Backfill Mining Method to Sequestrate CO2-A Case Study

The consumption of coal resources has caused an increase in CO2 emissions. A scientific concept that can realize sequestration, the harmless treatment solid wastes, and extraction under buildings, railways, water bodies (BRW) is proposed. First, a novel mineralized filling body (CMFB) developed by employing gas, fly ash, silicate additives, cement. It then injected into mined-out mining roadways (MRs) continuous extracting backfill (CECB) method to ameliorate overburden migration thus extract BRW. AHP-fuzzy comprehensive evaluation was employed construct prediction model for suitability this concept. Subsequently, generalized applied Yu-Shen area. Each indicator affecting adaptability plotted on thematic map, corresponding membership degree determined. aptness 400 boreholes distributed entire area determined zoning map which divides whole good, moderate, slightly poor, extremely poor drawn. This paper puts forward mathematical predicting using CECB CMFB sequestrate CO2. Research results provide references determining site sequestration premise maximizing economic ecological benefits, conducive constructing ecological, green, sustainable mines.
