Common Types of Mining Equipment

Mining equipment serves as the core machinery for the extraction, crushing, transportation, and processing stages of mineral operations. It covers a wide range of types with distinct functions. Common categories include drilling and blasting equipment, excavating and loading machinery, conveying systems, and various auxiliary tools. Each type is designed to adapt to different mining conditions, such as open-pit and underground operations. The following section provides a detailed introduction to the specific applications and characteristics of various mainstream mining equipment types.

Drilling and Blasting Equipment

The rotary drilling rig, along with percussion rock drills, is considered one of the two mainstream drilling equipment in the mining industry. It is also a core piece of equipment for blasting drilling, widely used in open-pit mine blasting drilling, oil well drilling, rock pre-splitting drilling, and mine expansion excavation.

1. Rotary Drilling Rig

The rotary drilling rig’s drill bit rotates under pressure to cut the rock, and compressed air is used to promptly remove rock debris, keeping the borehole clean. The standard borehole diameter is 152.4–558.8 mm, and the depth is 9.14–18.29 meters. Under special conditions, it can achieve borehole depths exceeding 45 meters. For example, SANY Rotary Drilling Rig can even reach a maximum drilling depth of 120 meters.

2. Percussion Rock Drills

Unlike rotary drilling rigs, which use cutting to create holes, percussion rock drills rely on reciprocating impact pressure to complete the drilling. They also use compressed air to blow away debris from the hole, ensuring the drill bit continuously and stably cuts into new rock layers. This makes them more suitable for shallow and small-diameter drilling. For example, external piston models are mainly used for drilling holes with a diameter of 127 mm or less.

Excavating Equipment

Also known as a hydraulic mining shovel, this machine uses a hydraulic system to drive the bucket, enabling efficient excavation of hard materials. Equipped with a tracked or wheeled chassis and a rotating cab, along with an articulated arm, it can operate flexibly within a circular working range without frequent repositioning. Its main uses include earthmoving and ore transportation, ore layer excavation, material loading assistance, and short-distance transportation of ore from the overburden layer in open-pit mines.

2. Electric Rope Shovel

The electric rope shovel replaces the hydraulic system with a rope-and-pulley system for the bucket at the end of the robotic arm. It is electrically driven and designed for heavy-duty excavation, enabling efficient bulk material handling in mining operations. Its functions are similar to hydraulic excavators, and its main applications include: overburden and working face preparation in open-pit mines, excavation of hard materials, earthmoving, removal of large rocks, and transferring mined materials to loaders.

3. Roadheader

A cantilever roadheader consists of a cutting head, a conveying and loading device, and a crawler-mounted walking mechanism. Roadheaders typically use two main types of cutting heads: transverse (ripping) and axial (milling). Transverse heads are better suited for harder rock conditions, while axial heads are more effective in softer to medium-hard formations and allow more precise cutting control. The SANY Roadheader uses a five-jaw integrated star wheel cutting head, offering stable operation and strong adaptability. Classified into three major series—large, medium, and small—based on working conditions and scale, it is designed to meet the requirements of various coal and rock strata environments.
