Mining is the technology and science of extracting mineral resources from the earth's crust and surface. Mining in a broad sense also includes the extraction of coal and oil. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials.
Exploration is one of the important working methods of engineering geological exploration. Engineering geological exploration includes geophysical exploration, drilling, and pit exploration.
In mining and exploration, professional and exclusive lubricants are widely used: for example: lubricating oil, gear oil, transmission oil, lubricating grease, hydraulic oil, heavy-duty diesel engine oil, etc.
