Welcome to an industry first 3D animated library for the underground coal industry.

The following animated posts are designed to explain products, concepts and principles that are commonly associated with the mining industry.

We will be continually adding new posts to this animated library so if you have any suggestions for further posts please contact us via our contact page.

Continuous Miner

A continuous miner is used to cut coal from the face and load it onto a shuttle car or conveyor in a continuous operation. It cuts the coal using its large rotating drum with the teeth on the drum scraping or ripping the coal from the seam. The primary...


These pressure rated hoses carry both air and water from one location to another in an underground mine. The standard clips used on the end of the hose allow for quick attachment to air and water supplies.



Containers are used  for transportation of goods to and from a mine site, and also provide an excellent resource for temporary onsite storage.  Typically either 20 or 40 feet long, and made of ribbed sheet steel they are strong and readily transportable on tru...

Crib Room Table

A crib room table is used underground primarily for meal breaks. With a fixed table and chairs it allows a small gang of miners the space to sit down in relative comfort. It is easily transported using pallet forks and oftenly situated in a cut through c...


A portal is the entrance and exit to an underground coal mine for people, machinery and services. It can also be a location for intake air to ventilate the mine. Most portals have a communication device such as a DAC or phone at the entrance to control the moveme...

Grout Bowl and Pump

The grout bowl is used to mix water and grout powder to form a viscous grout mixture. The grout is then pumped using the pneumatic piston pump via a hose to the site of use.  A common use for the mixed grout underground is in roof bolting. The grout...

Ballast Trailer

A heavy duty ballast trailer is used to transport and distribute ballast (small stones) around an underground coal mine. This ballast trailer incorporates a manual latch for the tail gate and an internal hydraulic push panel that automatically pushes the...

Roof Bolts

Bolts provide support to the roof and rib of roadways by clamping the layers of strata together.  Bolts come in varying lengths and design types to suit the specific geology of the rock mass in the roof or rib.   To install a bolt, a hole is firstly drilled t...


The airtrack is primarily a crawler mounted underground drill rig. This mechanical, self propelled heavy duty rig, drills holes into the coal roof and rib ready for the installation of bolts. It is normally used for installation of secondary roof supports i.e....

Drill Bit and Steel

The drill bit and steel are used for drilling long tenon bolt holes and boreholes into materials such as rock and coal. There are many design types of bit to suit differing drilling conditions, whether it be hard or soft, wet or dry. The tips are mad...
