Flux Analysis with the Application of Darcy’s Law Based on Borehole Data for Sustainable Groundwater Exploitation

open access: yesJurnal Ilmu Lingkungan
The potential for groundwater is very large and widely distributed in Aceh Besar District as indicated by the Groundwater Basin map. This potential is supported by the presence of sedimentary deposits consisting of materials such as gravel, sand and clay.

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Study on Key Controlling Factors of Fracture Propagation by Shaped Charge Blasting in Coal Seams

open access: yesEnergy Science &Engineering, EarlyView.
Gas drainage is the fundamental approach to controlling gas disasters in coal mines. For single low‐permeability coal seams, it should be supplemented by coal seam permeability enhancement technologies to improve gas drainage efficiency. This paper conducted a numerical simulation study on the key controlling factors affecting the fracturing effect of ...

Renewing the Exploration Approach for Mid-Enthalpy Systems: Examples from Northern England and Scotland [PDF]

open access: yes, 2015
After a promising start in the 1970s and 80s, the UK rather fell behind other countries in the search for viable mid-enthalpy geothermal resources.

Heat recovery from mineworkings: opportunities in the Glasgow area [PDF]

open access: yes, 2017
Glasgow is one of many locations within the United Kingdom once dotted with a number of thriving coal mines. Before the suitability of the water stored in mines can be determined for use in ground source heat pump (GSHP) heating applications, it is ...

Research on the Mechanism of Sand Bridge Stuck Drill in Deep Coal and Rock Gas Horizontal Wells

open access: yesEnergy Science &Engineering, EarlyView.
Accounting for wellbore collapse debris and the bulldozer effect, this study develops models for permeable and impermeable sand bridge sticking in deep CBM horizontal wells, deriving resistance and volume formulations. Validated in Changqing, results show impermeable bridges dominate; controls (fluid optimization, staged drilling, circulation, speed ...
