Abstract:

Pillar design is a crucial aspect of underground mining engineering, as it directly impacts the safety, stability, and overall effectiveness of mining operations. In this paper we present a method to calculate pillar stability based on the strain criterion and pillar load inversion concept, which complements the empirical pillar strength formulae. Those formulae do not account for certain parameters that can affect the stability of the pillars, e.g. weak layers, changes in stress orientations due to mining, orebody dip, mining layout complexity, and the influence of regional stabilizing pillar

Abstract:

The increase in mining depth necessitates higher strength requirements for hard rock pillars, making mine pillar stability analysis crucial for pillar design and underground safety operations. To enhance the accuracy of predicting the stability state of mine pillars, a prediction model based on the subtraction-average-based optimizer (SABO) for hyperparameter optimization of the least-squares support vector machine (LSSVM) is proposed. First, by analyzing the redundancy of features in the mine pillar dataset and conducting feature selection, five parameter combinations were constructed to exam

Abstract:

Most of the definitions of sustainability include three basic pillars: economic, environmental, and social. The economic pillar has always been evaluated but not necessarily in the sense of economic sustainability. On the other hand, the environmental pillar is increasingly being considered, while the social pillar is weakly developed. Focusing on the environmental and social pillars, the use of methodologies to allow a wide assessment of these pillars and the integration of the assessment in a few understandable indicators is crucial.

The design also depends on the number, persistence, orientation, and strength of the discontinuities with respect to the orientation and magnitude of the stresses presen

Urban parks are central to advancing urban sustainability and improving overall quality of life by providing green spaces that promote physical and mental well-being, mitigate environmental issues, and foster community cohesion. However, there is a lack of methodologies that measure these benefits and provide a sustainability rating. In this study, we propose a valuable tool for measuring the sustainability level of urban parks: low (0–50%), medium (51–79%), and high (80–100%). It employs effective and affordable measures for the daily management of urban parks. It is rooted in the three pilla

Abstract The recurrent threats of infectious diseases, alongside escalating environmental and man-made disasters, underscore the critical requirement for robust public health emergency management (PHEM), which puts into practice the emergency management cycle consisting of prevention, mitigation, preparedness, response and recovery. PHEM is an emergent field of practice that draws on specific sets of knowledge, techniques and organising principles necessary for the effective management of complex health events. Effective PHEM is indispensable for minimising morbidity and mortality, safeguardin

Abstract:

Ukrainian electricity production sector is in a critical situation. It is necessary to increase the coal production to ensure the continuity of electricity production. In this paper, an analysis of coal mining in western Donbas, Ukraine, was presented. The crucial thing is to increase coal production in this region. The new calculation schemes were proposed to increase coal extraction in Donbas mines. The coal pillar parameters, which are necessary for the effective control of the rock pressure caused by the stooping, were substantiated. The obtained parameters for the coal pillars will allow

The transparency and quality of audits performed by professional accountants and auditors are of crucial importance for the functioning of the global financial infrastructure. Over de last decade, more and more auditors were confronted with the globalization of their clients and became so-called group auditors responsible for the overall quality of the audit engagement even if other auditors in other jurisdictions may be involved. It goes without saying that auditors around the globe do not work in the same environment, do not have to comply with the same rules and regulations and do not have

Abstract:

Mammalian auditory hair cells transduce sound-evoked traveling waves in the cochlea into nerve stimuli, which are essential for hearing function. Pillar cells located between the inner and outer hair cells are involved in the formation of the tunnel of Corti, which incorporates outer-hair-cell-driven fluid oscillation and basilar membrane movement, leading to the fine-tuned frequency-specific perception of sounds by the inner hair cells. However, the detailed molecular mechanism underlying the development and maintenance of pillar cells remains to be elucidated. In this study, we examined the

Improving the utilization of non-renewable resources takes a crucial position in circular economy. Gob-side entry driving technology has been widely applied in coal mines in China, such as in the Shilawusu mine (Ordos City, Inner Mongolia), here considered as a case study due to its high safety and resource-recovery rate. However, at present the complexity of coal pillar utilization makes it hard to fully master the key technology for coal pillar size design, which leads to huge waste of coal resources. Based on theoretical calculation and numerical simulation, this study analyzed the basic me

Abstract:

Detecting objects in 3D space using LiDAR is crucial for robotics and autonomous vehicles, but the sparsity of LiDAR-generated point clouds limits performance. Camera images, rich in semantic information, can effectively compensate for this limitation. We propose a simpler yet effective multimodal fusion framework to enhance 3D object detection without complex network designs. We introduce a cross-modal GT-Paste data augmentation method to address challenges like 2D object acquisition and occlusions from added objects. To better integrate image features with sparse point clouds, we propose Pil

Recognizing 3D objects from point clouds is a crucial technology for autonomous vehicles. Nevertheless, LiDAR (Light Detection and Ranging) point clouds are generally sparse, and they provide limited contextual information, resulting in unsatisfactory recognition performance for distant or small objects. Consequently, this article proposes an object recognition algorithm named Adaptive Scale and Correlative Attention PointPillars (ASCA-PointPillars) to address this problem. Firstly, an innovative adaptive scale pillars (ASP) encoding method is proposed, which encodes point clouds using pillars

According to the development requirements of green mining of coal resources, it is imperative to improve the extraction rate of coal and the application of safe and efficient mining technology. Pre-splitting and roof cutting technology is widely used in reducing residual coal pillars and safe pressure relief mining, which has become the crucial technology for pillar-free mining methods. Therefore, it is essential to review and discuss the research hotspots, cutting-edge methods, principles of action, and application areas of the development of this technology.

Abstract:

Pillar Two, proposed by the Organization for Economic Cooperation and Development (OECD), represents a paradigm shift in international taxation. However, its implementation could result in disputes under existing international investment treaties (IIAs). The investor-state dispute settlement mechanisms (ISDS) may become a relevant procedure for resolving those issues with tax carve-out provisions in IIAs being a key factor. This raises a few relevant questions: What is the purpose of tax carve-out clauses in the context of IIAs? What role do they have in tax-related disputes under investment a

As Pillar Two moves closer to implementation, its potential clashes with international investment agreements (IIAs) are gaining attention. Among other possible claims, the possibility of top-up taxes under Pillar Two amounting to expropriation under them is often mentioned.
