Mining Problems and Possible Solutions

14.02.2013The richest mining executives or the lowliest businessperson, politician, union organizer or consumer is pushed to produce or consume more and more, faster and faster. The social order of the world faces the mystery of how to balance need for growth and man's characteristic and predictably capricious nature.

We Hear You: Bitcoin Mining Noise Pollution Is A Solved Problem

02.06.2022Bitcoin mining is noisy. But mining farms are not the only type of computing infrastructure facilities receiving noise complaints. Noise pollution is an inherent problem for traditional data centers, too. And just like a bitcoin mine, noise levels of 90 dB or higher are common at most data centers.

Mining

Mining is currently not a statistically significant category of development-induced displacement. Nevertheless, the social costs of exploitation are great, and that is why the topic is worthy of a wider and more profound scientific analysis. The first displacement caused by mining dates back to th view more Keywords

Impact of seismic

07.06.2019The paper deals with seismic-type surface and building vibrations randomly occurring as a result of rockbursts in mining regions (random events as with earthquakes). The focus is on the problem of ground vibrations transmission to building foundation – it is one of very important phenomenon associated with soil-structure interaction effect.

Impact of mining-induced earthquakes is usually a significant inconvenience for people living in areas at risk. Earthquakes of this type may even cause structural damage to infrastructure. The seismic intensity assessment is currently based on specialized empirical scales.

Mining induced displacements a threat to rural livelihoods

13.01.2022In Zimbabwe, mining companies often fail to pay adequate and prompt compensation, give people adequate notice and follow due process before relocation and to provide proper relocation facilities and services before relocation. In the process they violate litany of procedural and substantive environmental social economic and cultural rights.

Geophysical Characterization of Mining

04.02.2022A small seismically induced disturbance may trigger ground motion if the rock mass stress reaches failure state. The disturbances caused by dynamic failure generally result in rock rupture, fracturing, fault slip, pillar failure, advancing roadways, and mining working face [ 14, 16 – 21 ].

Numerical Simulation of Mining

13.07.2021Overburden movement and mining-induced stress distribution show significant variation when the working face in mining is near fault. The considerable field practice shows that deep mining near fault is able to easily induce rock burst and mine earthquakes, and the frequency and degree of damage are significantly increased [ 2 – 5 ].

"A range of different factors cause mining-induced deforestation," Sonter explains.

Review of the Evolution of Mining

Characterizing of mining-induced fractures at a large scale is always a challenging problem. Traditional methods, such as borehole camera and borehole acoustic televiewer, can only observe the mining-induced fractures in small scale. As attenuation tomography is sensitive to the degree of fracture in the rock mass, so this technology will be a promising

Analysis of Mining

26.10.2021In Europe, due to the location of mining in highly urbanised areas, this problem is mainly related to the occurrence of mining damage to building structures. Usually, this includes damage to residential buildings, outages of transmission networks, and damage to transport facilities (roads, railways), e.g., [ 12, 13 ].

Mining induced seismicity

Damage due to seismicity has been observed in various mines around the globe [1]. Seismic events will occur as a result of blasting, fault slip, rockbursts or any other source of rock fracture and ground movement.

Mining-induced subsidence is nearly always very localized to the surface above the mined area, (or the sinking) of land resulting from groundwater extraction. It is a growing problem in the developing world as cities increase in population

Mining

Surface subsidence induced by mining subsidence affects the overlying buildings and nearby utilities. Therefore, an investigation of the internal displacement and surface settlement is very important. A small-scale transparent soil model was developed to study the surface settlement profile and displacement field induced by mining subsidence.
