Adoption of Non Pillar Sublevel Caving Method to Exploitation of Medium-Thick and Thin Orebody

While medium thickness inclined or sharply-inclined ore body was influenced by the breaking effect,and the open stoping method and filling method made no sense,this paper introduced the technology of sublevel caving method for mining. Practice shows that in the broken small ore body,using the sublevel caving mining method may lead the operator and equipment from the traditional mining roadway to the narrow inside,so the roadway will be easily maintained,the use of machinery and equipment can be more efficient,the operator can be safer,so the application of sublevel caving mining method in small and medium mining has broad prospects.
