Jun 30, 2019· List of mining equipment: Mining is the extraction of valuable minerals or other geological materials from the land of a deposit. For this extraction to be done efficiently, we need machinery specialized in mining. These mining equipment have reinforced chassis and more powerful engines so that they can transport all the material.
Personnel and Material Transport. The mode of mine access (e.g. vertical shaft, inclined drift, in-seam access via outcrop, etc) determines the nature of transport systems used to transport personnel and materials into the mine (shaft hoisting, drift haulage or rubber tyred vehicle access). However, the large majority of mines today use diesel ...
Other articles where Shaft is discussed: tunnels and underground excavations: …opening is usually called a shaft. Tunnels have many uses: for mining ores, for transportation—including road vehicles, trains, subways, and canals—and for conducting water and sewage. Underground chambers, often associated with a complex of connecting tunnels and shafts, increasingly are being used for such ...

Galloway hoists for Scissor Creek shaft construction Project: As part of its $2.8 billion capacity expansion project, Potash Corp of Saskatchewan undertook the sinking and development of a new service shaft at Scissors Creek near Rocanville, Saskatchewan.
The term "mantrip" means a vehicle or elevator used to take a work crew into and out of the mine. A vehicle that is being used for double duty, i.e., that may serve sometimes as a mantrip and at other times as a supply vehicle, would be considered a mantrip for purposes of this standard only when it is performing that function. Additionally ...
Shaft boring technology. Herrenknecht shaft boring systems stand for innovative machine concepts that reach deposits at great depths of up to 2,000 meters safely and efficiently. They thus meet all requirements of the modern mining industry: short construction times for deep shafts …
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
This system is used in other vehicles that require the torque and horsepower that this motor supplies. It is available with or without a 7/8" auxiliary shaft as well. The weight of the AC 50 and AC 51 motors are around 115 pounds/52.2 Kg. This motor is also very popular in the mining industry.
A vehicle for underground mine shafts includes a body having a cabin located in a front section of a vehicle with an entry to the cabin located at the front of the vehicle, a door at the entry, a sensor for sensing when the door is open and control circuitry which is connected to the sensor. The vehicle also includes vehicle brakes to activate the vehicle brakes when the sensor senses that the ...
mining - mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
Jul 29, 2021· Underground shaft mining: ... Biden set a goal for 50% of all vehicles sold in the U.S. to be "battery electric, plug-in hybrid electric or fuel cell electric" by the end of the decade.
Opal field shafts. Caldwell shafts are sunk during exploration drilling to provide ventilation and access/egress from underground workings on the opal fields. Often these shafts will be in-situ when a claim is pegged. Without adequate identification and guarding, these shafts present a major hazard.
Floating shaft couplings are specifically designed for long span applications from 24" to over 300". Tru-Tube composite tubes (shown) can be specified for spans up to 220" (6 meters). Composite tubes weigh up to 80% less than steel and can eliminate the cost of bearing supports and other structures.

Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.
Mar 19, 2018· In August 2016, multiple large-tonnage transport vehicles passed through the inclined shaft of the Jinjitian coal mine, Yulin, China, over a short period of time, resulting in fracturing of the floor, bearing capacity reduction, liquefaction of the underlying sand layer, and a serious water and sand inrush. The inrush and its sand content increased rapidly, with flows up to 72 m3/h, with up to ...

Shafts and shaft ends need guarding if they present a hazard. Rota tion speed, size, location, keyways, burrs and other factors need to be considered when determining which shafts need guarding. Not all shafts and shaft ends require guarding. The examples shown in Figure 15 contain protruding bolts, keys, and couplings and should be guarded.
