Dozer Push Mining Method

About Dozer Push Mining Method: 

• It is an unmanned, automated machinery to optimizes the mining process which ensures that vibration and flyrock are controlled within safe limits.
• It is an innovative approach developed by CSIR-CIMFR which aims to enhance safety and operational efficiency in mining processes.
• Advantages:
  • It offers a viable alternative to the conventional truck-shovel mining technique or shovel-dumper and dragline methods.
  • It offers distinct advantages such as improved efficiency by enabling faster coal recovery, reducing delays caused by adverse weather conditions such as the monsoon season and highly cost-effective, with an estimated 7-10% reduction in operational costs compared to conventional methods.
  • Additionally, it enhances productivity by improving the utilization of dragline machines and reducing unit costs.
  • Moreover, the unmanned operation of the Dozer Push Mining method greatly enhances worker safety, minimizing the risks associated with manual labor and traditional mining techniques.
