Yes, drilling in opencast mines is done both day and night. Drilling in opencast mines is mostly done at night or in the evening. The reason for this is that the face on which drilling is done, after blasting, which is done to extract OB (overburden)and coal. Sometimes due to the face being too big, it takes a lot of time to remove all the OB (overburden)or coal from the face. While working there is difficulty in doing drilling work and the face is also filled with stone and coal. That is why drilling is done only after the face is empty. In the mining sector, blasting is done from one side, which facilitates the extraction of coal and all the work such as -blasting, drilling, big-machine, dumper, dozer, haul pack, all the machines can easily go to the face and So that we can do our work easily.
