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

Energy Science &Engineering, Volume 14, Issue 2, Page 721-736, February 2026.
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 ...

A roadmap for China to peak carbon dioxide emissions and achieve a 20% share of non-fossil fuels in primary energy by 2030 [PDF]

, 2019
As part of its Paris Agreement commitment, China pledged to peak carbon dioxide (CO2) emissions around 2030, striving to peak earlier, and to increase the non-fossil share of primary energy to 20% by 2030. Yet by the end of 2017, China emitted 28% of the

Toward Decarbonization of the Titanium Industry via Hydrogen Plasma Smelting Reduction

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Progress in developments of dry coal beneficiation [PDF]

, 2014
China’s energy supply heavily relies on coal and China’s coal resource and water resource has a reverse distribution. The problem of water shortages restricts the applications of wet coal beneficiation technologies in drought regions.

Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...
