Ruinuo Inorganic Support Material — High-Water Content Inorganic Material for Roadway-Side Support and Backfilling in Coal Mines

Product Description

This product is a fully inorganic mineral powder material designed for direct mixing with 2–10 parts water. It features adjustable setting time, 100% hydrated consolidation, zero bleeding, rapid strength development, and long-distance pumping capability (~500m), making it ideal for backfill support under various mining conditions.


Product Features

  1. Long-distance pumping: Up to ~500m.
  2. Rapid early strength: 0.5–5 MPa achievable.
  3. Controlled deformability: ~5% compressive strain tolerance.
  4. Eco-friendly: Non-toxic, odorless, non-polluting, and non-corrosive.
  5. Safety: Flame-retardant with fire prevention functionality.
  6. Efficient construction: Simple and fast application.


Scope of application

  1. Backfill support for abandoned underground roadways.
  2. Construction of sealed walls with customizable safety grades and purposes.
  3. Consolidation and support for goaf areas and collapsed zones in small coal mines.
  4. Roadway retention along goaf edges.
