Application Cases

Ultra-high-water filling material – Paste-like high-water thickening additive

Our company produces a paste-like high-water thickening additive (ultra-high water filling material), which offers advantages such as simple processing, rapid setting speed, and stable performance when used for filling mined-out areas. It is widely applied in coal industry applications including longwall mining with backfilling, retaining roadways along existing entries, filling empty roadways, controlling roof collapses, reinforcing coal walls, providing side-entry support, sealing and extinguishing fires in mined-out areas, preventing spontaneous combustion, and enhancing the structural integrity of mine shafts and tunnels through thickened wall filling and support systems.

Quick-sealing material (quick-sealing material for top and bottom corners)

The Rapid Sealing Material (Rapid Sealing Material for Upper and Lower Corner Areas) is a next-generation product in the fire prevention and extinguishing category. It effectively addresses the issue of heat accumulation during the foaming and filling process, significantly enhancing flame-retardant performance compared to conventional products. Additionally, it’s easy to apply, environmentally friendly, and odorless—making it ideal for localized applications such as coal spontaneous combustion in roadways and on top of support structures, as well as sealing off air leaks in upper and lower corner areas.

FKL-1 Hole-Sealing and Leak-Stopping Material

The FKL-1 type mine-use inorganic hole-sealing grouting material addresses the key technical challenge of achieving highly effective sealing for underground borehole gas extraction. The primary function of this sealing grout is its inherent density, which allows it to form a tight bond with the borehole wall surface while completely filling and sealing any existing fractures or cracks.

Mining Inhibitor

Surface spraying of coal underground creates an isolation film between the coal and air; it prevents contact with oxygen and stops spontaneous combustion of coal; the inhibitor solution can withstand high temperatures of about 800℃~1000℃; a stable, antioxidative, flame-retardant, water-containing film forms on the coal surface, fully wrapping coal particles to isolate oxygen and prevent fire.
