Face Drilling and Development Drilling Tools
Face drilling or Development drilling refers to the process of drilling holes directly into the "face" or exposed surface of a rock or mineral deposit in mining, tunneling, and construction activities.
Face drilling requires skilled operators who are knowledgeable about the geological conditions, drilling techniques, and safety protocols. Ensuring the stability of the face during drilling is crucial to prevent accidents, rockfalls, or collapses.
