Abstract:

Based on the analysis of geological conditions and mining technical conditions of the mine,as well as the calculation of reserves and comparison of mining methods,the mechanized upward-horizontal sublevel filling mining method,ordinary upward-horizontal sublevel filling mining method,shrinkage and subsequent filling mining method,and resuing and filling mining method were selected and the corresponding block arrangement mode and stope structure parameters were optimized.The research on mining preparation,cutting,stoping,and filling technology was also conducted.The mining method change of Yejiatian Fluorite Mine has realized the safe and efficient mining of the steeply inclined thin ore veins in the fault structure zone,providing a reference for the efficient development and utilization of strategic mineral resource fluorite in China.
