👉 Sapingia, also known as a sapping machine or a drilling machine, is a type of mining equipment used for extracting ore from underground mines and caverns. It consists of two sets of drill bits, which are mounted on rotating shafts that rotate in opposite directions to create a suction effect. The purpose of the sapping process is to remove the top layer of rock and debris from the mine, allowing the lower layers to be mined more effectively.
