Title: Quanlin Shi: Inventor Advancing Mine Fire Prevention

Introduction

Quanlin Shi is an inventor based in Jiangsu, China, whose work focuses on materials and methods for preventing and controlling coal-mine fires. He is associated with China University of Mining and Technology and is named on 2 patents.

Latest Patents

Shi’s listed inventions address air leakage and spontaneous combustion in underground coal mines.

“Fire-prevention and extinguishing material for plugging air leakage in underground barrier pillar of coal mine and use method thereof” describes a layered material designed to seal air leakage in a mine barrier pillar. Its flexible intermediate layer contains cement powder and evenly distributed fiber filaments. A flame-retardant upper fabric layer can deform under pressure to block oxygen, while a water-soluble lower fabric layer completes the structure.

“Fly ash-based environmentally-friendly hydrogel with high water retention for preventing and controlling spontaneous combustion of coal in mine and preparation method thereof” presents a hydrogel made using fly ash and other materials. The formulation combines a gel-forming mixture with a crosslinking mixture that includes zeolite, expandable graphite, and an aluminum citrate complex. The disclosure describes the hydrogel as degradable, water-retentive, and adjustable in gelation time, with the aim of keeping coal wet and helping limit spontaneous combustion.

Career Highlights

Shi’s patent work applies material design to practical mine-safety challenges. The inventions described here focus on reducing oxygen access to underground coal and maintaining moisture around coal to help prevent or control fires.
