Iron ores refer to ores containing iron, mainly including hematite, magnetite, limonite, and siderite, generally buried deep underground. The rocks containing iron ores are usually hard and solid.

DTH drilling rigs utilize a combination of percussive and drilling mechanisms, with the hammer directly acting on the rock to drill holes to reduce energy loss, which makes DTH drilling method suitable for iron mining. JK Drilling has developed a wide range of drilling rigs to meet the needs of iron ores applications, such as the models of JK730, JK810-3, JK820-2 and JK830-2.
