Study on the diffusion and migration law of CO2 sequestrated in abandoned coal mine goaf

Deep Underground Science and Engineering, EarlyView.
The goaf of an abandoned coal mine, endowed with expansive fracture spaces and an abundance of residual coal, can be capable of sequestrating substantial quantities of CO2. The residual coal is the principal medium for the sequestration of CO2 in the form of adsorption and the amount of sequestration is considerable.

Comparation Study of the Use Naftalena from Coal Tar Waste with Camper Napthtalene as Concrete Admixture [PDF]

, 2020
Concrete is a mixture of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate, and water, with or without additives (admixture). The naphthalene superplasticizer used comes from distillation of coal tar and a little from the rest ...

Strain‐based modeling and analysis for rock blasting and geomechanics applications

Deep Underground Science and Engineering, EarlyView.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

Tri‐axial compressive behavior of high‐water material for deep underground spaces

Deep Underground Science and Engineering, EarlyView.
The relationship between the mechanical behavior and microstructures of the laterally confined high‐water material associated with water bleeding was established. Abstract Attributed to its superior water‐to‐solid ratio and quick setting time, the high‐water material is widely adopted in underground spaces as a cost‐effective and environmentally ...

Production capacity prediction of U-shaped horizontal wells for in-situ pyrolysis of tar-rich coal: Experimental and numerical simulation study

Meitan xuebao
Under the goal of “dual carbon”, “taking hydrogen and retaining carbon” has become an inevitable choice for the clean utilization of coal, and underground coal pyrolysis provides a new idea for increasing domestic tar and gas production.
