The development and equipment requirement of sublevel caving with large structural parameters

Sublevel caving has the advantages of simple stope structure,safety and high productivity.It became the principal caving method quickly since it was introduced into China in 1960s.With the use of high-power mining equipment in recent years,it is larger structural parameters of stope increasing production efficiency and reduce mining cost that has been became the main development trend of sublevel caving.Combining with actual conditions of mines in China,coordinated development of mining technology and equipment of thick orebody and steeply inclined medium thick orebody was discussed from the production needs of large structural parameters.
