Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job. For mining operations to be successful good blast designs are absolutely vital as poor practices and excessive explosives can result in damage to rock structures causing unwanted caving.
Based upon a recent investigation of truck vs. rail haulage in bituminous-coal mines, Toenges and Jones conclude that with equipment in its present stage of development and within the range of conditions studied, for a new mine a dual haulage system would effect a saving in transportation cost if the round-trip haul exceeds 2.7 miles. The first use of trucks for large-scale open-pit haulage in
According to the Bureau of Labor Statistics, the mining industry consists of five major segments: coal mining, gas and oil extracting, metal ore mining, non-metal mineral mining and supporting activities such as resource transportation. Each segment requires the use of specific equipment, but there are several types of mining equipment that are used throughout the industry. This equipment
West Cumbria Mining won planning permission from Cumbria County Council on 19 March, 2019, to open a mine in Whitehaven but, unlike others on this list, this will be a deep mine. It wants to use the £165m Woodhouse Colliery site to extract one billion tonnes of coking coal about 2.5 million tonnes annually from under the Irish Sea.
Change in production and productivity of US coal mines The higher productivity for open pit mining equipment also lowers costs. The necessary underground equipment for maintaining productivity is more expensive on a unit basis capacity than corresponding open pit equipment. Furthermore, the large production scale and share number of open pit mines have provided the opportunity for
The metal mining application segment dominated the global mining equipment market in 2019 owing to increase in hauling of metal deposits and high demand for precious metals. Factors such as favorable government regulations, growth of the mining-related end-use industries, and fluctuation in the commodity prices are expected to significantly affect the demand for mining equipment in the metal
Coal mining Coal mining Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many

In open pit mining, equipment selection is made according to many factors related to the ore and mining conditions. These factors can be qualitative and quantitative in nature. The main purpose of equipment selection is to choose the optimum and cost-effective equipment by installing a decision-support system, which can analyse various and complex factors. The term optimum here reflects that
Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious
