CSIR-CIMFR Achieves Milestone with First Trial Blast of Dozer Push Mining Method
In a significant milestone for the mining sector, the CSIR-Central Institute of Mining and Fuel Research (CSIR-CIMFR) has successfully conducted the first trial blast of the Dozer Push Mining Method in India. This innovative approach integrates advanced digital technologies to improve safety and operational efficiency in mining processes. The trial took place at the Parsa East and Kanta Basan (PEKB) Coal Mine, operated by Adani Enterprises Limited in Chhattisgarh. This achievement marks a pivotal moment in the evolution of mining practices in India.
The Dozer Push Mining Method: A New Era
The Dozer Push Mining Method represents a paradigm shift in mining operations. Developed by CSIR-CIMFR, this method utilizes unmanned, automated machinery to streamline processes. The trial involved drilling 108 holes using an automated drill machine, followed by cast/throw blasting with 60 tons of bulk emulsion explosives. After the blast, a specially designed large-sized automated dozer machine pushed the blasted material into the decoaled area.
This method is designed to optimize the mining process while ensuring that vibrations and flyrock are controlled within safe limits. The project, which has been in development for two years, focused on adapting the Dozer Push Mining Method to local conditions in Indian coal mines. The successful trial demonstrates the potential of this innovative approach to enhance safety and efficiency in mining operations.
Advantages Over Conventional Methods
The Dozer Push Mining Method offers several advantages compared to traditional mining techniques, such as truck-shovel and dragline methods. One of the most significant benefits is improved efficiency. This method allows for faster coal recovery, reducing delays caused by adverse weather conditions, such as the monsoon season. Additionally, it is highly cost-effective, with an estimated reduction of 7-10% in operational costs compared to conventional methods.
Moreover, the unmanned operation of the Dozer Push Mining Method significantly enhances worker safety. By minimizing the risks associated with manual labor and traditional mining techniques, this innovative approach prioritizes the well-being of workers. The method also improves the utilization of dragline machines, further enhancing productivity and reducing unit costs.
Future Prospects and Next Steps
The successful trial of the Dozer Push Mining Method was led by Prof. Arvind Kumar Mishra, Director of CSIR-CIMFR, along with a dedicated team of scientists and technicians. The initial trial demonstrated effective drilling and charging operations, precise detonation with minimal environmental impact, and efficient material movement using automated machinery.
Looking ahead, the second phase will involve conducting 8-10 additional trial blasts to refine the blast design further. The final recommendations will focus on optimizing the method for widespread implementation across the Indian mining industry. This breakthrough has the potential to set a new benchmark in mining practices, making them more efficient, cost-effective, and safer.
The Dozer Push Mining Method marks a significant advancement for the Indian mining industry. By adopting cutting-edge technologies, this innovative approach promises to enhance safety, efficiency, and cost-effectiveness in mining operations. As the industry evolves, the successful implementation of this method could revolutionize mining practices in India and beyond.
