The argillaceous sandstone samples were collected from the exposed surface of the mercury-thallium mine after mining (Fig. 1).A total of three profiles (S1–S3) were collected at depths of 0–7 cm, and each profile collected three samples, According to the different degrees of weathering, the samples were described as a grey-black external layer, a brown-yellow middle …

Sand and gravel typically are mined in a moist or wet condition by open pit excavation or by dredging. Open pit excavation is carried out with power shovels, draglines, front end loaders, …

[67], [75], and the damage-induced fluid inrush into excavations introduces an enormous risk to civil and mining engineering projects. In this context ...

There are a number of techniques for separating a mass of stone from the parent mass. For many years the primary technique was the wire saw, which consists of a single-, double-, or triple-stranded helicoidal steel wire …

The process of sandstone quarrying hinges on two primary extraction methods: surface quarrying and underground mining. Surface quarrying, also known as open-pit mining, is the more common of the two methods.

The amount of waste generated is also minimal in contrast to the production processes involved in creating prominent materials like concrete bricks (Kristensen, 2016). ...

The communities have been sidelined from the process of negotiating mining contracts with LSM companies. The environment is ...

The mode of transport of soil particles during wind erosion is governed by soil particle size (Jia et al., 2015).The moisture content of the soil in these arid regions is less than 10%, and hence it does not prevent erosion of fine particles (Silva et al., 2015).Hence greater amounts of finer particles are transported due to the Aeolian process leading to massive …

Frac sand is a naturally occurring silica material extracted from high-purity sandstone, which plays a critical role in fracing. Frac sand's compressive strength allows for the steady release of oil and gas, but …

Artisanal sandstone mining (ASAM) is generally characterised by the use of basic and simple tools (e.g. hammer and chisel) to extract stone from quarries. The stone is used in …

variety of sandstone in terms of its colour and texture. Due to a surge in exports during the last two decades, there has been an increase in the number of sandstone quarrying and processing units in Jodhpur and nearby areas. Currently, sandstone quarrying and processing is one of most important sectors of Jodhpur's economy (Bhadra et al., 2007).

Specifically, the in-situ stress unloading during the mining process yields a more significant impact on the initial structural deterioration of coal compared with sandstone, which is attributed to the fact that the coal possesses much larger initial D f and D d and a lower K v than sandstone. This is mainly due to the fact that more primary ...

The escalating levels of atmospheric carbon dioxide (CO 2) and their significant impact on global climate change have emphasized the critical necessity of carbon capture, utilization, and storage (CCUS) strategies [[1], [2], [3], [4]].Carbon sequestration, particularly through mineralization, has emerged as a crucial approach for long-term carbon storage, effectively mitigating greenhouse …

Sandstone is a sedimentary rock comprised of lithified sands. Most is primarily quartz sand or a mix of quartz and feldspar sands in conjunction with interstitial cementing materials including …

Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. ...

Sandstone's primary uses include dressed stone for flagging, ashlars, and partially squared pieces as well as rough blocks for building and construction (Dolley 2007). Two general phases of sandstone production exist: quarrying and processing. Each of these phases is described below.

Devonian rocks supply a variety of mineral resources. A Devonian sandstone formation known as the Sylvania Sandstone located at or near the surface in Wayne and Monroe counties contains high silica, uncontaminated sand grains. Mining sandstone involves different techniques (i.e., blasting, crushing, etc.) and the process is more expensive.

1. Introduction. Water shortage in western China has severely limited the development of the local coal industry. The operation of the underground water reservoir in the coal mine avoids the loss of mine water and alleviates the water shortage in the arid western region. 1 Daliuta coal mine is the earliest group of underground reservoirs built in China's …
