Feasibility of microbially-solidified coal gangue particles as vegetation substrate for vegetation restoration
Qifan Yang
The feasibility of coal gangue particles solidified with microbially-induced carbonate precipitation technology (MICP) as vegetation substrate for vegetation restoration is studied by solidification tests, microscopic tests, and pot tests. Test results show that the strength, water retention, and anti-wind ability of coal gangue particles can be improved by MICP. The main products of MICP solidifying coal gangue particles are calcite and vaterite. Under low solidification degrees, the shape of C
