Coal Geology & Exploration

The development of geothermal energy in coalfield can not only improve the temperature environment of coal mining, but also turn waste into treasure through the clean utilization of geothermal energy. Especially, it is of great prospect to store energy in the mined-out area of coalfield under the “dual carbon” goal at present. Herein, in this paper, it was estimated that the geothermal reserves in the main coal-bearing areas of China were 1.12 × 1019 kJ, equivalent to 379.539 billion tons of standard coal, and the recoverable geothermal reserves were 1.71 × 1018 kJ, equivalent to 56.931 billion tons …

Unleash The Heat: Exploring Geothermal Energy Perspectives And Energy Literacy In São Miguel, Azores, Lena Mcdonough Apr 2023

Unleash The Heat: Exploring Geothermal Energy Perspectives And Energy Literacy In São Miguel, Azores, Lena Mcdonough

Independent Study Project (ISP) Collection

The green energy transition is moving ahead in EU countries at very different paces, and there are some key challenges that all regions currently face in trying to phase fossil fuels out of their energy mixes. One of these challenges is that most regions simply cannot harness enough renewable energy sources and simultaneously have the storage technology for creating a baseload power source as reliable as oil, coal and natural gas. That is, unless you sit in the middle of the Atlantic Ocean on the boundary of three tectonic plates, with a continuous and reliable renewable energy source beneath your …

A Transition Point: The Role Of The Global Power Shift In Facilitating Saudi Internal Reforms, Aidan Aguilar Apr 2023

A Transition Point: The Role Of The Global Power Shift In Facilitating Saudi Internal Reforms, Aidan Aguilar

Independent Study Project (ISP) Collection

The increasing political and economic influence of China represents a pivotal point within international relations. This paper aims to explore the implications of this global power shift on Saudi Arabia’s attempted economic reforms. The Kingdom’s reliance on oil has created an unsustainable economic model, and this model is intrinsically linked to Saudi Arabia’s relationship with the United States. Its growing relationship with China could create change. As such, this paper analyzes the intersection of economics and security in relation to the Saudi Vision 2030. I argue that, not only does China serve as an important source of the investment necessary …

Diagnostic Gold Deportment Studies And Leaching Behaviour Of Small-Scale Gold Mining Tailings From Eastern Region, Ghana, Ishmael Quaicoe, Martin Beyuo, Solomon Quaicoe, Nikao A. Lasidzi

Journal of Sustainable Mining

Artisanal and small-scale gold mining (ASGM) sector employs about 80% of the mining workforce but only contributes about 20-30% of Ghana’s gold production. The low gold production is linked to low recoveries associated with the activities because ofinadequate understanding of the chemical, mineralogical and metallurgical characteristics of the ores. This study examined the metallurgical characteristics of typical small-scale gold mining tailings to understand their grinding characteristics, gold deportment and cyanidation behaviour. The gold deportment results showed that 96.1% of the gold in the samples is free milling (can be leached directly with cyanide and recovered through carbon adsorption), whilst the …

Research On Aquifer Water Abundance Evaluation By Borehole Transient Electromagnetic Method Based On Fcnn, Cheng Jiulong, Wang Huijie, Xu Zhongzhong, Huang Qisong, Jiang Guoqing

Coal Geology & Exploration

Predicting the location and water abundance of aquifers by drilling or geophysical methods before tunneling is very important to prevent water disasters in advance for the safety of coal mine production. The use of borehole transient electromagnetic method (BTEM) for advanced detection has obvious advantages. At present, the interpretation method is based on the calculated resistivity to qualitatively analyze rock water abundance, and it is impossible to predict the aquifer water abundance grade. So, the fully convolutional neural network (FCNN) method is proposed to predict the aquifer water abundance grade for BTEM. Firstly, according to the Archie formula, Kozeny-Carman formula, …

Challenges And Solutions To High-Resolution Data Processing For Seismic Exploration, Cao Siyuan, Sun Yaoguang, Chen Siyuan

Coal Geology & Exploration

The seismic resolution has long been limited to the quarter wavelength. To compress the seismic wavelet, the key problems are signal-to-noise ratio (SNR) and resolution in early stages, and high resolution and high fidelity in late stages. Meanwhile, by using well data, many inversion methods of spanning quarter wavelength have been developed. The success of these methods depends on the preservation of seismic wave amplitude, the accuracy of seismic interpretation, and the compatibility between well data and seismic data. Afterward, researchers achieved seismic inversion without well data constraint, and the corresponding resolution reached the level of reflectivity. Meanwhile, the key …

From 1d To 4d: Advances And Thoughts On Coal Seismic Technology, Cheng Jianyuan, Zhang Xianxu, Jiang Bici, Wang Pan, Shan Rui

Coal Geology & Exploration

As one of the key technologies for safe and efficient support of coalmine geology, the seismic technology, has gone through one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D), and progressed from resource exploration to mining area exploration, and from structural exploration to lithological exploration. The latest 4D seismic will further leapfrog from static detection to dynamic detection. Based on the concepts of time-space dimensions and the four seismic development stages, we propose three transitional stages from 1.5D (e.g., non-zero offset VSP), 2.5D (e.g., wide line 2D seismic exploration) to 3.5D (e.g., 3D seismic dynamic interpretation), and also present the time-space characteristics …

Coal Geology & Exploration

The shallow coal resources in North China have been nearly depleted so far, whereas deep coal development is challenged by karst water inrush in floor limestone. The conventional underground vertical hole grouting methods are troubled with inappropriate site location, thin drilling-met aquifer, large grouting blind area, and inaccurate target location. For this reason, we propose an advance regional control technology: bedding directional drilling-based grouting. We systematically study the slurry flow from near-horizontal grouting holes, advance grouting modes, grouting parameter control, advance identification of potential water diversion channels, as well as validation and assessment of a grouting treatment. On this basis, …
