BHP Mitsubishi Alliance (BMA) has announced the completion of the electronic blast at the Caval Ridge coal mine in Australia. The coal project is located at Bowen Basin, Central Queensland. Explosives supplier Dyno Nobels DigiShot technology was used for the blast.
Sealing underground mines with inflatable ventilation control devices (VCDs) State mining legislation requires underground coal mines to have provisions for Ventilation Control Devices (VCD) and mine sealing, in case of underground emergency to protect against spontaneous combustion and explosions. M2P designs and manufactures rated compliance seals.
The most recent of these blasts was at a central Queensland coal mine when 7350 AXXIS electronic detonators were fired in a single pattern kilometres long. the Blasting Guide application

Coal mining plays very important role in most of the developing countries to meet the energy demands. But the same time mining industry is implant electronic sensors in different sectors. They variation of the resistance of the device. Here it
National Coal Board ideally creating zero earth fault current. For this condition to happen the inductive current should be equal to three times the charging current for the system. This method is not suitable for coal mining electrical distribution systems because the stray capacitance of a mine system is always changing due to operational
