Drilling means penetrating the stone. Penetration of rocks is sometimes done in order to crush them. To break the rocks, you have to dig an explosive hole and put explosives inside them. By blowing up the holes, the rocks are crushed, and by crushing the rocks, it is easier to extract and harvest, and it is done at a lower cost. In the extraction of all mines, except in rare cases such as the extraction of building stones or the extraction of some loose stones, drilling is considered an inevitable operation, which is called extractive drilling. Drilling in mines is not only for extraction, but also before extraction or during extraction for exploration. Exploratory drilling may be done to discover the presence of a mineral or mineral or to find out the quality of rocks. Due to the high cost of exploratory drilling and some technical problems, it is recommended that both groups of experts who are looking to discover the mineral or to find out the quality of the rocks, start their studies at the same time.
