Research on the Critical Moisture Content of Frost Heaving in Gas-Containing Coal

Pengwu Han,
Zhaofeng Wang,
Xingying Ma
et al.

Abstract: As the depth of coal seam mining increases, coal and gas outburst prevention and control face unprecedented challenges. In recent years, freezing outburst prevention technology has received attention and been applied in industry; this method mainly improves the strength of the coal body while reducing its energy storage. Research has shown that due to the influence of moisture content, frost heaving occurs in coal bodies during the cooling process, weakening the coal bodies' strength. Therefore, it is necessar… Show more
