Dozer Push Mining Method Revolutionises Indian Mining

The CSIR-Central Institute of Mining and Fuel Research (CSIR-CIMFR) achieved a milestone by successfully conducting the first trial blast of the Dozer Push Mining Method. This innovative approach integrates advanced digital technologies and aims to enhance safety and operational efficiency in the mining sector. The trial took place at the Parsa East and Kanta Basan (PEKB) Coal Mine in Chhattisgarh, operated by Adani Enterprises Limited.

Overview of Dozer Push Mining Method

The Dozer Push Mining Method represents shift in mining operations. Developed by CSIR-CIMFR, it utilises unmanned, automated machinery for mining tasks. This method is designed to optimise the mining process while controlling vibration and flyrock within safe limits.

Trial Details

The trial involved drilling 108 holes using an automated drill machine. Following this, cast/throw blasting was executed with 60 tons of bulk emulsion explosives. The blasted material was then pushed using a specially designed, large-sized automated dozer machine.

Advantages of the Method

The Dozer Push Mining Method offers numerous advantages over conventional techniques. It improves efficiency by enabling faster coal recovery. It also reduces delays caused by adverse weather conditions, such as the monsoon season. Operational costs are estimated to decrease by 7-10% compared to traditional methods.

Safety Enhancements

Worker safety is a primary focus of the Dozer Push Mining Method. The unmanned operation minimises risks associated with manual labour in traditional mining techniques. This innovative approach aims to create a safer working environment for miners.

Future Phases of Implementation

Following the initial trial, the second phase will involve 8-10 additional trial blasts. These trials will refine the blast design further. Final recommendations will aim to optimise the method for broader implementation across Indian coal mines.

Contributions of CSIR-CIMFR Team

The successful trial was led by Prof. Arvind Kumar Mishra, Director of CSIR-CIMFR. The project team included experts such as Dr. Murari P. Roy and Dr. Vivek K. Himanshu. Their collaborative efforts were very important in the development and execution of this innovative mining method.

Implications for the Mining Industry

The introduction of the Dozer Push Mining Method marks advancement for the Indian mining industry. It marks the potential for integrating cutting-edge technologies to enhance safety, efficiency, and cost-effectiveness. This breakthrough sets a new benchmark for future mining practices in India.
