“…Some researchers have found that the freezing front moves downward with decreasing temperature, and the liquid water content of the soil decreases at all depths [19]. Some researchers have found that soil water moves towards the freezing front, and the decrease in liquid water is related to the location of the freezing front [17]. The results are relatively consistent.…”

“…Some researchers have also analyzed the movement patterns of soil moisture under various snow cover conditions [16]. The mechanism of hydrothermal interaction was analyzed through one-year on-site dynamic observations of the hydrothermal state, frost heave, and freezing depth [17]. Hou et al analyzed the corresponding moisture, salt, and temperature functions in soil samples using an indoor, unidirectional freezing test [18].…”

In order to conserve valuable soil and water resources and avoid problems related to frozen soil, it is important to study the migration of frozen soil water. A greater understanding of frozen soil–water migration can assist with sustainable development and utilization of soil and water resources in frozen areas. This study used an indoor soil column test device to conduct a one-way indoor freezing test of unsaturated soil and the response of soil sample water migration to different freezing temperatures, initial moisture contents, soil densities, freezing times, solute concentrations, and solute types. The experimental and analytical results showed that the temperature field of the soil sample could be divided into three stages: sharp cooling, slow cooling, and stability. After the soil sample had been frozen for 100 h, the temperature field stabilized. The freezing temperature, initial water content, soil density, and freezing time affected water migration in the soil sample. Lower freezing temperatures and greater initial water content resulted in higher levels of water migration. By contrast, greater soil density led to lower water migration levels. In addition, longer freezing times produced smoother soil–water migration curves. The solute concentration and solute type also affected water migration in frozen soil; the higher the solute concentration, the greater the water migration. Compared with CaCl2, NaCl had a stronger effect, causing more water migration and leading to a higher water content. The research findings will aid further studies on soil and water utilization, environmental maintenance, and restoration in areas with seasonally frozen soil, as well as promote the sustainable development of agriculture, water conservancy project development, and the social economy.

“…Freezinginduced groundwater migration and the resulting water table recession have been observed in many countries like the US (Daniel and Staricka, 2000;Drescher, 1955;Meyer, 1960;Schneider, 1961), Canada (Ireson et al, 2013;Pan et al, 2017;van der Kamp et al, 2003), Sweden (Stähli et al, 1999), Russia (Vinnikov et al, 1996) and China (Lyu et al, 2022;Yi et al, 2014;Wu et al, 2016;Zhang et al, 2019). Moreover, by transporting water and dissolved ions from groundwater to seasonally frozen soils, freezing-induced groundwater migration would strengthen the possibilities of frost heave (Chamberlain, 1981;Bronfenbrener and Bronfenbrener, 2010;Rui et al, 2019) and soil salinization (Qin et al, 2021;Wang et al, 2022). Nevertheless, there is still limited quantitative understanding of the conditions that groundwater can be migrated to seasonally frozen soils.…”

“…The air flows in an underground confined space, causing the surrounding rock cooling and airflow heating due to the mutual influence of heat exchange between surrounding rock and airflow, which is a complex dynamic coupling process. A lot of efforts have been invested to study these heat exchange problems based on the methods of experiment (Rui et al, 2019) theoretical analysis (Liu et al, 2019) and numerical calculation (Ma et al, 2018). Jiang et al (2021) explored the temperature distribution law of high-speed railway tunnel under the action of piston via computational fluid dynamics, and obtained the temperature disturbance range of tunnel entrance and tunnel exit under different train speeds.…”

The heat damage in a coal face of a high-temperature mine is a significant mine disaster owing to various heat sources. Understanding the influence of various heat sources on the air temperature distribution in the coal face can help us to determine reasonable working conditions. Therefore, it is necessary to take into account the coupling relationship of multiple heat sources and obtain accurate prediction results. In this paper, the finite volume calculation method is used to establish a numerical model of heat dissipation of surrounding rock considering the difference in thermal and physical properties of coal and rock in the coal face. And then, a high-temperature coal mine in the northeast of China is taken as an example to explore the airflow temperature distribution law of the coal face under the influence of the absolute heat source and the relative heat source via the finite difference method. Furthermore, an orthogonal test was performed to investigate the influence degree of major factors on heat exchange of the coal face through range analysis. This work supplements the existing numerical model and research, and provides a theoretical basis and more accurate practical methods for predicting the thermal environment of coal face, especially in high mining depth mines.
