Abstract:

The technological and technical possibility of deep processing of coal by its liquefaction using the methods of extreme mechanochemical and physical effects has been determined; recommendations have been developed for the applied use of the obtained materials in heat power engineering. The organic part of the solid mass of the prepared coal-oil suspension, which has turned into a relatively heavy organic liquid, can be used as a boiler or motor fuel, as well as a feedstock for the production of various hydrocarbon liquids. The resulting mixture of hydrocarbons can be subjected to rectification

Abstract:

The phenomenon of liquefaction is the transformation of coarse-grained soil from a solid to a liquid state, resulting in a reduction in the bearing capacity of the soil due to an increase in hydrostatic pressure due to a sudden high cyclic load. Liquefaction usually occurs during an earthquake, where earthquake-triggering factors, ground acceleration, water table depth, overburden pressure, soil density, and soil type are used as input data. A fuzzy-GIS approach is used to combine these factors to map liquefaction potential. This method produced a preliminary map of liquefaction potential in S

Considering its clean and environmental characteristics, natural gas has gradually attracted attention from countries around the world. China’s coal-to-gas project has significantly increased the country’s demand for, and supply of, natural gas. Liquefied natural gas (LNG) has also been gradually promoted, owing to its advantages of easy storage and transportation. However, the natural gas liquefaction process includes multiple phases, and each phase generates substantial industrial pollutants, such as CO2, SO2, and NOx. Despite this, the resulting environmental impacts have not been quantitat

Abstract:

ACARP Report C4057 (Eckersley, 2000) describes flowslides and other stability issues in stockpiles of coking (metallurgical) coal at Australian coal operations and export terminals, and summarizes 1973 to 2000 research at James Cook University (JCU). Eckersley (2022) partly updated that work with SEEP/W transient seepage modelling of a 12m high coal stockpile constructed at Hay Point in late 1991. Eckersley (2023) summarized available laboratory strength data for saturated and unsaturated coking coal to assist in selection and critical assessment of parameters for slope stability analyses of c

Abstract:

Tailings facilities of large mining and processing plants are particularly responsible structures the destruction of which can cause serious environmental and socio-economic consequences. One of the factors affecting the safety of the operation of such facilities is strong seismic effects caused by earthquakes of tectonic and technogenically induced nature. Tailings facilities are technogenic facilities that significantly change the engineering, geological and landscape situation of territories. Anthropogenic changes in the geological environment associated with the construction and operation

Abstract:

This dedication aims to design a Coal Production Data Management System at PT. Mitra Terminal Kaltim using the Waterfall method to enhance efficiency. Coal production data, including hauling, crushing, barging, coal getting, stock reporting, and daily reporting, is currently manually managed using Excel, resulting in process inefficiencies. Through systematic design steps, this dedication emphasizes the User Interface (UI) to expedite and streamline the production data processing. The expected outcome is to support coal production monitoring more swiftly and efficiently.

Abstract:

The current energy and climate crisis calls for immediate action in replacing fossil fuels with those derived from renewable sources. The Energreen process performs the direct liquefaction of biomass to produce a liquid biofuel for the cement industry and an aqueous solution of added-value compounds for further processing. The present work details the development of an Aspen Plus® model to simulate this biomass liquefaction process. The proposed model describes the Energreen liquefaction process using simplified reaction kinetics and thermodynamic models. The model was validated using data fro

ABSTRACT Since 2009, 91 new strong-motion stations were built for the renewal of the Swiss Strong Motion Network. Another nine stations will be installed until 2022. For each new station, an extensive site characterization study is performed to model the 1D seismic-velocity profile and, for some sites, the liquefaction potential. Geophysical (passive and active surface-wave methods) and geotechnical cone penetration test (CPT) with additional pore-pressure measurement (CPTu) and seismic CPT (SCPT) methods are used.

Study on multivariate calibration for infrared spectrum of coal was presented. The discrete wavelet transformation as pre-processing tool was carried out to decompose the infrared spectrum and compress the data set. The compressed data regression model was applied to simultaneous multi-component determination for coal contents. Compression performance with several wavelet functions at different resolution scales was studied, and prediction ability of the compressed regression model was investigated. Numerical experiment results show that the wavelet transform performs an effective compression

Abstract:

Derived from a larger scale project, which studied geomechanical issues associated with coal seam gas (CSG) production, this paper investigates a hypothetical case study based on the Latrobe Valley, Gippsland Basin, Victoria. The paper focuses on examining aquifer water management associated with CSG production-related water extraction. As such, the paper limits itself to determining the volume of water production from a hypothetical case study area in the Latrobe Valley. A simplistic property model and methane production strategy has been used. The impact of extraction of this water on the hy
