Abstract
The ore bodies of Shandong Xintai Company are mostly thin to medium thick gently inclined veins,with inclined ore bodies with an inclination angle of 30° to 45° accounting for 26%.Both room pillar mining and shrinkage mining methods are used to recover such ore bodies with low production efficiency.In response to this problem,this paper proposes the practical application of vertical slicing and pseudo inclined working face room pillar mining method based on the optimization and adjustment of mining technology for inclined thin ore bodies,Practice has proven that this method can effectively reduce the dip angle of the mining face,facilitate drilling,slag removal,and other operations,improve production efficiency by more than 20%,and achieve good economic benefits.It is worth popularizing and using for reference,allowing more reasonable development and application of mine resources.关键词
