“…In accordance with [79], the application of mine filling technology is proposed as a remedial measure to address stability concerns within a large-scale stope group located in a lead-zinc mine in Inner Mongolia. The authors introduced an enhanced Mathews stability chart method that accounts for geometric parameters, surrounding rock conditions, and mining sequence of the stopes.…”

Coal mine solid waste backfill is a coal mining method employed to safeguard subterranean and surface geological formations, as well as water resources, against impairment. It stands as a pivotal technical approach for realizing ecologically sustainable mining endeavors, aiming to address China’s predicament of ’three down’ coal pressure, coal gangue emissions, and land resource scarcity. This manuscript delves into an in-depth exploration of the evolution and research status pertaining to solid backfill technology, encompassing backfill materials, rock mechanics, backfill processes, and their application across China’s coal sector. The developmental challenges and technical intricacies linked to solid backfill technology within coal mines are meticulously scrutinized. Building upon these challenges and complexities, this study sets forth a progressive trajectory for solid backfill technology within the contemporary era. This trajectory envisions the synchronized advancement of novel solid backfill materials, intelligent surveillance and regulation methodologies, and machine learning technologies for backfill quality assessment. By doing so, the overarching aim of achieving superlative quality, heightened efficiency, and automation in solid backfill practices can be effectively realized.

“…Goaf collapses can cause severe environmental problems, such as surface collapse, which not only impacts the ecological and geological environment but also greatly affects the development of the local mining economy [25]. For SM mines, managing and maintaining the mining area is more challenging and can result in serious safety hazards, such as cave-ins [26].…”

Despite China’s position as a global mining powerhouse, tens of thousands of small- and medium-sized mines (SM mines) within the country continue to pose potential safety hazards and environmental pollution risks. Only through the identification of suitable development paths can these mines improve their economic and environmental benefits, ultimately driving significant progress in China’s mining industry. Backfill mining, an environmentally friendly mining method, has emerged as a viable solution, offering the potential to ensure mining safety, reduce environmental pollution stemming from tailings stockpiles, and enhance ore resource recovery. This review article aims to provide researchers and readers with a comprehensive understanding of the current situation and challenges faced by SM mines in China. It explores the mining processes, technologies, and equipment commonly employed by these mines while addressing the specific problems and challenges they encounter. Furthermore, the article offers recommendations to guide the future development of SM mines. Additionally, the review examines the prospects and potential applications of backfill mining methods within the context of SM mines in China, emphasizing their role in promoting sustainable mining practices, environmental protection, and waste utilization. Ultimately, this comprehensive review article serves as a valuable resource, stimulating discourse and encouraging experts and scholars to further explore the unique challenges and opportunities associated with SM mines. By highlighting the significance of green mining practices, environmental protection, backfill mining, and waste utilization, the article aims to inspire innovative solutions and foster sustainable practices within the Chinese mining industry.

“…If the compaction and cementation strength of the filling inside the collapsed column is low, under the influence of external factors such as the mining disturbance of the working face and the water pressure of the aquifer, the collapsed column is very likely to generate activated water conduction, and become the connection between the overlying aquifer and the mining working face. Water diversion channel between them, causing major safety accidents such as water inrush and flooding of wells from collapsed columns [7].…”

In order to analyze the relationship between the configuration characteristics, variable mass permeability characteristics and the catastrophe mechanism of falling column process, The influence of the permeability was studied by diffraction instrument, And using the seepage test system of the fall column, The seepage instability process of variable mass broken rock mass is analyzed, The findings suggest that, The proportion of coarse particles accounted for 89.86%, Fine particles accounted for 10.14%, Broken rock particles is better, Low compression performance; The fall column, under strong hydrodynamic conditions, Due to its strong characteristics of migration and loss with water flow, It is easy to induce the subsidence column protrusion water disaster; As the ratio between coarse and fine aggregates increases, Porosity and permeability are both increased; When the axial displacement does not change, With the increasing circumference pressure, The permeability of the broken rock samples is decreasing; The fitting of the seepage velocity of the broken rock mass to the pore pressure gradient follows the Forchheimer relationship, The seepage of the broken rock mass belongs to the category of non-Darcy flow under the triaxial stress; The instability of the subsidence column fracture rock mass presents three seepage instability forms: initial seepage stage, seepage mutation stage and piping stage in different stages.
