Special Issue Information

Dear Colleagues,

As an important basic energy, coal has made great contributions to the development of human society. At present, in order to control the emission of carbon dioxide, we are trying to reduce the use of coal and realize its clean utilization as much as possible. Methane from coal-bearing measures (including coalbed methane) is an important unconventional clean energy source. The mineralogical and geochemical information of coal and coal-bearing strata is not only helpful for us to understand the formation mechanism of coal and coal-bearing strata, but also helpful for us to realize the clean utilization of coal.

This Special Issue is organized into the following sections:

  • Section 1. Advances in sedimentology of coal-bearing strata;
  • Section 2. Advances in mineralogy and geochemistry of strategic key metals (such as Ga and Ge, etc.) in coal;
  • Section 3. Advances in mineralogy and geochemistry of hazardous elements in coal;
  • Section 4. Advances in methane of coal-bearing measures.

This Special Issue aims to contribute to the disclosure of advances in mineralogy and geochemistry of coal and coal-bearing strata in order to better understand the formation mechanism of coal and coal-bearing measures, as well as the clean utilization of coal.

Gallium (Ga) is a typical scattered trace element that is irreplaceable in strategic sectors such as national defense, wireless communications, new materials, renewable energy, and healthcare. The coal–Ga deposit is an important complement to traditional Ga resources and has become a significant focus for Ga mineral resource exploration. Therefore, there is an urgent need to research the coal–Ga cooperative exploration model from both technical and economic perspectives. Taking the Heidaigou coal–Ga deposit as an example, the enrichment zone of coal–Ga is predominantly situated in the northern part of the exploration area, adjacent to the fault zone. The Ga concentration demonstrates a gradual decline from the north–central region towards the northeast and southeast. Similar vertical Ga distribution patterns are observed in adjacent drillings, with notably higher concentrations in the roof, floor, and parting layers. The cooperative exploration model for coal–Ga deposits is proposed based on the above features. The model employs a comprehensive set of cooperative technical methods, such as remote sensing, geological mapping, seismic exploration, drilling, petrogeochemistry, and well logging. The layout of exploration engineering and the concentration of Ga provide the basis for the estimation of Ga resources. Additionally, the model provides an important scientific basis for the improvement of the strategic coordination ability of Ga mineral resources. Full article
