[Objective] Rock fragments are ubiquitous in soil, especially in arid and semi-arid regions. They have a considerable influence on various subsurface hydrological processes. Understanding the impact of rock fragments on these processes is crucial for improving water resource management, ecosystem restoration and sustainable development. [Method] This paper reviews the research over the past decades on the influence of rock fragments on subsurface hydrological processes, highlighting the challenges and limitations we currently face and proposing potential research perspectives. Specifically, we analyze the effects of characteristic parameters of rock fragments, such as their coverage, content, and size, on water infiltration, surface runoff and subsurface flow, preferential flow and soil evaporation. We also review progress in mathematical models used to simulate and quantify the effects of rock fragments on subsurface hydrological processes. [Result] Our review reveals that the mechanisms underlying the influence of rock fragments on subsurface hydrological processes remain obscure, and current methods are unable to capture the complex causal relationship between rock fragments and soil hydrological processes. Areas such as quantification of rock fragment heterogeneity and its association with soil hydrological parameters, multi-scale modelling of soil hydrological processes are still in the infant stage and require further work. [Conclusion ] We propose that developing innovative technologies and methodologies, and improving understanding of the underlying mechanisms are particularly important in future research. Specifically, future research should focus on characterizing rock fragments in deep soil and their influence on hydrological process and formation of preferential flow, methods to link gravel content to hydrological information at different scales. Improving research in these areas will advance our in-depth understanding of the impact of rock fragments on soil hydrological processes, helping develop sustainable water resource management in arid and semi-arid regions.

Coal mining in Jurassic coalfields of the arid Northwest area has damaged the local water resources greatly. Basing on the analysis of diachronic changes of the drainage and water balance of Jinjie Coal Mine, the paper gave some explanations of the changes of circulation patterns of groundwater before and after the mining. According to the changing characteristics of the water levels of pore water, fissure water and mixed water of double aquifers before and after mining, it was believed that the variation of the hydraulic properties of the roof aquifer in the mining area is mainly induced by the unified evolution of the transmission and closing property of roof aquifuge during the promoting process of mining face. The variation of the transmission and closing property of roof aquifuge changes the circulation pathways of mine groundwater, and the heavy-water deposits could be formed in the arid area. Also, the paper holds that the prediction method of real-time mine inflow based on variations of roof hydraulic properties will be one of the key issues in the future studies of deposit hydrogeology.
