摘要
叙述了中深孔留矿法在广西大新锰矿的应用。分析中深孔留矿法的特点,并针对其特点提出与浅孔留矿法相结合进行采矿。通过实践,此法充分发挥了中深孔留矿法与浅孔留矿法各自的优点,提高了采矿主要技术经济指标,获得了良好的经济和社会效益。
With the emphasis on the application statement of medium-length hole shrinkage method in DaXin Manganese Mine,this paper has analyzed the features of medium-length hole shrinkage method,putting forward a method which combines with shallow hole shrinkage method specific to these features.In practice,the method makes full use of the merits of medium-length hole and shallow hole in shrinkage method,and it improves main technical and economical technological and economic technological and economic indexes of mining,and finally it receives good economic benefits and remarkable social benefits.
