“…For gold mines, the water accumulated in the cavity can most often be accessed and treated as a point source. Coal mining is more composite however, and it may not be possible to avoid uninhibited draining of AMD from restored opencut mines [49]. Thus, the state of water in these regions should be anticipated to decline.…”

South Africa is the home of major global mining operations, and the acid mine drainage (AMD) contribution has been attributed to abandoned mine sites and huge pyrite-bearing tailings from coal and gold mines. Determining the true economic impact and environmental liability of AMD remains difficult. Researchers have been looking into several treatment technologies over the years as a way to reduce its possible environmental impact. Different methods for active and passive remediation have been developed to treat AMD. The aim of this review was to describe the AMD-impacted environments and critically discuss the properties of AMD and current prediction and preventative methods and technologies available to treat AMD. Furthermore, this study critically analysed case studies in South Africa, gaps in AMD research, and the limitations and prospects offered by AMD. The study outlined future technological interventions aimed at a pattern shift in decreasing sludge volumes and operational costs while effectively improving the treatment of AMD. The various treatment technologies have beneficial results, but they also have related technical problems. To reduce the formation of AMD, it is recommended that more preventive methods be investigated. Moreover, there is a current need for integrated AMD treatment technologies that result in a well-rounded overall approach towards sustainability in AMD treatment. As a result, a sustainable AMD treatment strategy has been made possible due to water reuse and recovery valuable resources such sulphuric acid, rare earth elements, and metals. The cost of AMD treatment can be decreased with the use of recovered water and resources, which is essential for developing a sustainable AMD treatment process. More study is required in the future to improve the effectiveness of the various strategies used, with a focus on reducing the formation of secondary pollutants and recovery of valuable resources.

Залежність зміни σ max у стояках (а) та верхняку (б) від типу встановлюваного кріплення [52] З одержаних залежностей можна зробити висновок, що кріплення із композитних матеріалів постійного перерізу доцільніше використовувати у гірничих виробках через більш рівномірний розподіл напружень по усьому контуру рами. За рахунок пластичності вуглепластиків елементи кріплення можливо збільшувати або зменшувати [53], як позує кріплення змінного перерізу, тим самим враховуючи зміну гірничо-геологічних умов (ведення очисних робіт, надробка, підробка, тощо).…”

Purpose. To analyze composite materials and prospects of their use for roof support in coal mines. Research methodology. To achieve this purpose, we used analytical data on the market of composite materials, the volume of their production capacity, and cost indicators. Data on the physical and mechanical properties of composite materials and their quantitative indicators were used. Research results. The areas of application of composite materials in industry are analyzed and summarized. The analysis shows that composite materials are used in many areas of industry: medicine, construction, defense, etc. A comparative analysis of the physical and mechanical properties of carbon fiber-reinforced plasticand steel shows that this composite material has identical (and sometimes even better) properties than metal materials. The study concluded that it is better to use carbon fiber as a support material for mine workings in coal mines. The advantages and disadvantages of carbon fiber-reinforced plasticas a roofing material for coal mine workings are evaluated. It is clarified that the current limiting factor is the cost of carbon fiber-reinforced plastic, but over time, their price will decrease and their demand will increase. It is concluded that the use of this composite material in the elements of mine support can increase the pace of their implementation, reduce the labor intensity of the work performed and improve the working conditions of miners while lightening the structure. Scientific novelty. The physical and mechanical properties of composite materials have been analytically determined and it has been substantiated that carbon fiber-reinforced plasticsupports can be used in the support of preparatory workings in coal mines. Practical value. The obtained results prove that the support made of carbon fiber-reinforced plasticwill facilitate the design of the support, which, together with the acceleration of the shift operation, will contribute to the development of underground coal mining.
