Geological and geotechnical aspects of underground coal
The decision on whether to operate an above- or underground mine is heavily influenced by a couple of important factors. The major factor in deciding on whether to go underground or open cut is the stripping ratio (Whittles et al. 2007).This is defined as the ratio of the volume of overburden (BCM) moved to the amount of coal produced Just over 40 Mt of CMM were released to the atmosphere in 2022, representing more than 10% of total methane emissions from human activity. Steam coal and lignite accounted for around 75% of CMM emissions and coking coal for the remaining 25%. Underground mines were responsible for around 70% of emissions and surface mines for the remainder.Strategies to reduce emissions from coal supply

Research on the Evaluation of Air Quality in Underground Coal
In this study, an optimization model was established based on the generalized contrastive weighted comprehensive scale index method. This model gives the evaluation indicators of SO2, NOx, CO, and TSP. It also innovatively introduces gas, the most harmful substance in underground coal mines, into the evaluation indicators. By igniting in the coal seam and injecting gas agent, underground coal gasification (UCG) causes coal to undergo thermochemical reactions in situ and, thus, to be gasified into syngas for power generation, hydrogen production, and storage. Compared with traditional mining technology, UCG has the potential sustainable advantages in energy, Monitoring and Control in Underground Coal Gasification:

A Review of Research on Advanced Control Methods for Underground Coal
Underground coal gasification (UCG) is a clean coal mining technology without significant environmental impacts. This technology can also be used in deep, hard-to-reach seams or deposits affected by tectonic disturbances, where conventional mining is impossible. Several techniques and methods have been investigated worldwide to With the large-scale mining of coal resources, the huge economic losses and environmental problems caused by underground coal fires have become increasingly prominent, and the research on the status quo and response strategies of underground coal fires is of great significance to accelerate the green prevention and control of coal fires, Combustion mechanism and control approaches of underground coal

Comparison of Underground Coal Mining Methods Based on
Coal is China’s main source of energy, and its production causes a certain degree of air, water, and land resource pollution. Therefore, it is necessary to compare environmental pollution caused by different mining methods. When mining underground coal resources, different mining methods have different levels of environmental impacts. To The impact of coal mining subsidence on surface ecology involves the influence of several ecological elements such as water, soil, and vegetation, which is systematic and complex. Given the unclear understanding of the synergistic change patterns of the water–soil–vegetation ecological elements in the influence of coal mining in the west, this Effects of Underground Coal Mining on Soil Spatial Water
