Study on Deformation Law of Crossing Layer Drilling Superimposed Floor Roadway

Energy Science &Engineering, Volume 14, Issue 6, Page 2752-2771, June 2026.
Based on deformation law of crossing layer drilling superimposed floor roadway, low dip angle drilling is particularly susceptible to complications such as borehole blockage and collapse. ABSTRACT Floor extraction roadway crossing layer drilling is a pivotal strategy for gas control in areas prone to coal and gas outbursts.

Experimental Investigation of Sensitivity for Coal and Gas Outburst Risk Prediction Indexes in Raw and Tectonic Composite Coal Seams

Energy Science &Engineering, Volume 14, Issue 6, Page 2772-2784, June 2026.
A comparative study was conducted on gas desorption laws of raw and tectonic coals. The sensitivity of regional and local outburst prediction indexes was compared. Gas content is more sensitive than gas pressure for composite coal seams. K1 can more accurately predict the outburst danger than Δ h 2 in composite coal seams.

Alkali Vapor Corrosion of Spinel (MgAl2O4) and Gahnite (ZnAl2O4) Refractories—A Comparative Study

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Alkali vapor corrosion is critical for refractories used in the kilns and furnaces of diverse high‐temperature processing and manufacturing sectors such as gasifiers, cement production, and glass making. Gahnite (ZnAl2O4) is being investigated as a potential chrome‐free refractory because of its similarity with the structure and properties of ...

Experimental and Theoretical Investigation on the Progressive Breaking Law of Thick and Hard Rock Strata in Deep Mining

Energy Science &Engineering, Volume 14, Issue 4, Page 1881-1902, April 2026.
This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...
