Rock/explosive interaction SLIM uses current available technologies as cost-effective solutions to be implemented inexpensively by SME operations. Different tools like in-house MWD (mining while drilling) systems, photogrammetry, LiDAR and optical televiewer have been applied to assess pre and post blast rock characteristics and guide production planning towards a more efficient performance of Optimizing blast fragmentation to improve comminution efficiency The Run-of-Mine (ROM) size distribution has a large impact on the performance of downstream crushing and grinding processes. The in-situ ore properties, drill blast pattern, and properties of the explosive govern the size distribution of rocks produced from a blast and the energy efficiency of the blast.

NEW TECHNOLOGY IN OPEN CAST MINING

Such a flamboyant growth in the coal production can only be met through large sized opencast mines in future. Out of the two broad modes of mining i.e. opencast and underground, the emphasis is given mainly on opencast due to its favorable economics, safety, large coal recovery, better output per manshift (O.M.S) and also lower gestation period.

mines adopt the inseam gas drainage method to control the gas concentration. However, the labor production efficiency, including the replacement efficiency of working face, is no-tably low because of the poor gas permeability of coal seam, the low concentration

National Institute of Technology Rourkela This is to certify that the thesis entitled " Optimization of Blasting Parameters in Opencast Mines " submitted by Sri Manmit Rout (Roll. No.: 10305019) and Sri Chinmay Kumar Parida (Roll. No

Drones for mining: Quick deployment. Extreme

Surveying mines Exploring for minerals Monitoring stockpile volumes Tracking equipment Time-lapse photography Complete UAV Solutions Ideal for Mining For the mining industry, the sky's the limit when it comes to the potential of drones to improve efficiency

Using the spot operation data of dragline in Heidaigou Surface Mine,we studied the operational period,distribution rule,and the bucket fill factor of dragline operation so as to further discuss the operation efficiency.In addition,we analyzed factors affecting the operation

If you improve efficiency in one area of the cycle other parts may suffer as a result, so again a holistic approach to the entire cycle is needed. In addition, there is no one fit solution that fits all applications or problems so in most cases some customer tailoring is necessary.

It is possible to improve fragmentation, i.e. smaller particle size by using excessive explosives, at high cost. Drill and Blast Design and Planning Drill and blast design is an important part of mine planning and management, with major impact on safety and efficiency.

As one of the world's most experienced operator of continuous opencast mines, RWE played a key role in the successful realization of this project in Hungary. We helped transfer knowledge of international practices and standards in the areas of heavy equipment and continuous operation in opencast mines

In order for coal mines to survive and mine profitably, they need to capitalize on the opportunity to improve their productivity and focus on one factor they can control: operational efficiency. Increasing productivity is one of the key drivers to counter diminishing profit margins.

Optima are delighted to reveal that they have been supporting Cobham Antenna Systems on an exciting project to create a suite of tools to improve the effectiveness of explosive hazard clearance. Land Mines and Improvised Explosive Devices [IEDs] present an enduring global threat, killing an estimated 15,000 to 20,000 people per year of which approximately 80% are civilian [1] .
