Mechanical injuries mainly refer to injuries caused by direct contact between moving (stationary) parts, tools and machined parts of mechanical equipment and human body, such as attacks, collisions, shearing, winding, twisting, grinding, cutting and stabbing. Exposed transmission parts (such as gears, shafts, rails, etc.). ) and various reciprocating parts of rotating machinery may cause mechanical damage to human body.
At the same time, mechanical injury is also one of the most common injuries in non-coal mine production. Mechanical equipment that is easy to cause mechanical damage includes: transportation machinery, tunneling machinery, loading machinery, drilling machinery, crushing equipment, ventilation and drainage equipment, mineral processing equipment and other rotating and transmission equipment.
