Block caving is a highly resource-efficient method of underground mining, in which large underground ore blocks are cut from beneath, allowing the ore to collapse under its own weight. After collapsing, ore is drawn through drawpoints and conveyed to a crusher. In DOZ block caving, LHD loaders transfer ore slurry into ore passes leading to chutes.Underground Mining Equipment Market Size 2023- Future Challenges, Growth Opportunities, Upcoming Trends and Forecast Report 2033: SPER Market Research Neha Shrivastav 4moquartz ore mining crushing manufacturing process LinkedIn

IMPORTANT BASICS OF MINE VENTILATION AND
For effective and successful overall hot-rock mine planning the vent/cooling designs must command a high priority in a structured, systematic and multi-disciplinary forum. Future underground mining, particularly in RSA gold and platinum mining, will inevitably progress deeper and will have extremely high vent/cooling costs.The architecture is applicable for both open pit and underground mining operations. This solution is therefore key to digitizing mining use cases to achieve significantly improved safety and business relevant outcomes. Likewise, autonomous trucks can haul resources from shovels or front-end loaders in a mine to a crusher area. Industrial Automation in Mining Environments Cisco
