Spontaneous combustion of residual coal in longwall goaf is a long standing hazard. Airflow leakage into major driver to the hazard and this issue deteriorates where longwalls are operating multiple seams shallow covers because mining-induced cracks very likely draw fresh airflow due presence pressure differential between face surface. To study problem more critically, ventilation simulation package "Ventsim" used conduct case from Bulianta colliery. It was found that isolating pressurizing...
The design of a multimodal logistics service network with customer time windows and environmental costs is an important challenging issue. Accordingly, this work established model to minimize the total cost concerns. proposed incorporates CO2 emission determine optimal transportation mode combinations investment selections for transfer nodes, which consider transport cost, time, carbon emission, window constraints. Furthermore, genetic heuristic algorithms are set up abovementioned model. A...
Abstract In the field of electronic information science, with continuous advancement signal processing technology, filtering technology has become particularly important due to its ability effectively suppress noise and extract useful information. This article focuses on exploring an innovative method for rapid optimization filters. By designing a hollow cylindrical dielectric ceramic combining it traditional inductive structures, bandwidth return loss characteristics intelligent filters at...
Filling with phosphogypsum is one of the important ways to realize sustainability development phosphate mines. This study based on extensive on-site experiments conducted at Dayukou mine. Over a period 60 days, different proportions phosphogypsum, cement, and mineral powder were used fill voids in No. 1 2 test ore pillars. The results strength testing during experimental process indicate that filling material various stages normal, meeting all requirements for mining production....
An experimental study was undertaken to examine the sorption and desorption characteristics of coal at temperatures 35 °C, 45 °C 55 °C. The focused on effect changes in temperature particle sizes gas characteristics. size used ranged from fragmented coals, 16 mm, 8 2.4 powdered 150 μm 54 mm core samples. samples were tested pressure vessels, known as "bombs", charged with CO2 different levels up a maximum 4000 kPa. It found that has significant influence behaviour coal. degree hysteresis...
Mine ventilation has always been critical for underground mining operations to ensure operational efficiency and compliance with safety health statutory requirements. To obtain a thorough understanding of the flow characteristics on longwall face, innovative three dimensional (3D) models, incorporating key features equipment zone immediate goaf area, were developed. Mesh independent studies conducted determine desirable mesh required mesh-independent solution. Then model results validated...
Understanding the roles of properties nanomaterials in biological interactions is a key issue their safe applications, but surface atomic arrangement, as an important property engineered (ENMs), remains largely unknown. Herein, interfacial (affinity sites and intensity) between monolayer MoS2 zebrafish embryos mediated by 1 T phase arrangement (octahedral coordination) 2H (triangular prism nanosheets were studied. T-MoS2 first bound to phosphate then proteins on chorion, while adhesion...
This study presents a market model that procures energy and performance‐based regulation services simultaneously considering the participation of storage devices. The correlations energy, capacity, mileage are explicitly demonstrated. proposed determines schedule generation units, charging discharging profiles devices, services. Market clearing prices for derived decomposed through Lagrange multiplier analysis. relationships between different products analysed. is tested verified with IEEE...
Aqueous lithium-ion batteries (ALIBs) are attracting intense attention because of the intrinsic nonflammable nature aqueous electrolytes. However, its own narrow electrochemical window has led to numerous problems such as dissolution electrode materials, hydrogen evolution at anode, and poor cycling stability. Here, we report an "overcrowded electrolyte" using 1,4-dioxane additive, which lone pairs electrons on oxygen atom disrupt original water-hydrogen bonding network by forming...
Fish show variation in feeding habits to adapt complex environments. However, the genetic basis of preference and corresponding metabolic strategies that differentiate remain elusive. Here, by comparing whole genome a typical carnivorous fish (
In this article, we introduce the concepts of Hom–Long equation and dimodule. We discuss how dimodules are connected to equation. As main result, study FRT-type theorem for
