Abstract The residual coal pillar and adjacent goafs in the upper coal seam have a superposition effect on the stress environment of the lower coal seam in close distance coal seams with downward mining. Therefore, it is...

The global transition to sustainable energy systems requires breakthroughs in electrochemical storage technologies that are not only safe but also resource efficient. Solid-state batteries (SSBs), which use superionic so...

To investigate the influence mechanism of roof pre-splitting blasting on overlying strata movement in automated roadway formation without coal pillars, the mechanical response characteristics of the bearing structure of ...

In underground mining and tunneling projects, directional fracture-controlled blasting is critical for precise tunnel formation and reducing over- and under-excavation. However, the presence of well-developed joints in r...

Laterite soil is essential in the construction industry, especially in road and building construction. The practice of abandoning borrow pits after mining laterite soil in the Northern Region of Ghana has resulted in lan...

Bologna is the first major Italian city to become a ‘30 km/h City’, following the example of many other European cities. Since its launch in 2022, the ‘Bologna Città 30’ Plan has marked the beginning of a techni...

Bangladesh is highly susceptible to recurrent and devastating floods due to its geographic location. This research investigates the application of Geographic Information Systems (GIS) in developing flood evacuation route...

Abstract Failures of flexible pavements have been attributed to the indiscriminate use of lateritic soils without prior characterisation. This study investigates the compaction behaviour of lateritic soils at Ife-Sekona ...

El campo de la política es y ha sido en un sentido decisivo y radical, un producto de la creación humana. La forma que tenemos de pensar las actividades que identificamos como políticas o los conceptos que utilizamos ...

In the past, country house research was mainly concerned with individual houses and gardens. Yet, as early as the seventeenth and eighteenth centuries, so many country houses were being built around the major cities that...

The new airport project in Sanya planned by government of Hainan Province of China, is located at Hongtangwan of Sanya City, that is, to build an offshore airport with an area of a 28 square kilometers. The construction ...

Forest fires have exhibited an escalating trend in both frequency and intensity globally, with major and catastrophic events causing significant damage to forest resources, human lives, and property. Timely and accurate ...

Globally, several countries have begun to promote the application of building information modeling (BIM) technology and implement BIM-based building e-Permit systems. Despite the relatively rapid updates in the field of ...

El artículo propone una alternativa teórica metodológica para estudiar el proceso de construcción socio-material de la Carretera Austral en la Patagonia Occidental (Chile) durante la dictadura cívica militar de ese ...

This study proposes a deep-hole directional blasting technology based on polymer energy charge packages for roof cutting and pressure relief as a solution to difficult roadway support and poor stability of coal pillars d...

The relationships among the soil shear modulusobtained by oedometer tests, by pumping tests and the initial shear modulusof hardening soil small (HSS) model for soft soil under sensitive circumstance in Shanghai and Tia...

The technology of borehole pressure relief is an effective way to reduce the elastic energy accumulation in the surrounding rock of roadways, which can reduce the risk of regional rock bursts. Therefore, the studies on t...

Good air tightness of filter membranes is necessary for opening excavation chamber under high pressure. To improve the value of air tightness, one should understand the pore structure and permeability change of filter me...

Rapid economic growth in several South American countries combined with high species diversity in tropical regions has raised great concern among ecologists on the future of wildlife in those areas. One of the con- seque...

El presente trabajo de Tesis Doctoral constituye el resultado de un proceso de investigación llevado a cabo en la región centro-oeste de la provincia de Catamarca, República Argentina. El objetivo general consistió e...
