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 ...

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 ...

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...
