Pyrite Mine Backfill Aggregate

1. Mine Goaf Backfilling

✅ Pain Point

Traditional filling sand, gravel raw materials are in short supply, high purchase cost; ordinary filler loose structure, easy settlement, cannot effectively seal empty areas, bring major safety hazards.

✅ Solution

5-30mm low-grade pyrite particles with stable texture, proper gradation, natural compactibility, perfect raw material for underground mine filling project.

✅ Data & Result

Low water absorption rate below 3.2%, natural stacking density stable, filling solidification strength reaches standard mine safety requirement, greatly cut overall filling engineering cost.

✅ Usage

Mix with cement, fly ash according to mine filling proportion, pump or dump directly into underground goaf area.

2. Underground Roadway Stabilization

✅ Pain Point

Mining roadway side wall easy collapse, ground pressure extrusion leads to wall cracking, frequent reinforcement maintenance wastes plenty of manpower and material resources.

✅ Solution

Hard texture low-grade pyrite particles fill wall gaps and foundation gaps, form dense supporting layer, enhance overall roadway structure firmness.

✅ Data & Result

Effectively disperse underground ground pressure, reduce roadway deformation rate by over 45%, extend service cycle of mine roadway greatly.

✅ Usage

Used for roadway wall backfill, base bedding and surrounding rock auxiliary stabilization construction.

3. Ultra Low Cost Filling Material

✅ Pain Point

High-grade ore used for filling causes serious resource waste, long-term large-scale filling brings huge economic pressure to mining enterprises.

✅ Solution

Adopt 20%-30% sulfur low-grade waste pyrite material, make full use of surplus mineral resources, replace expensive traditional filling aggregate.

✅ Data & Result

Unit filling material cost reduced by more than 35% compared with conventional aggregate, large supply stable stock, suitable for long-term mass mine filling construction.

✅ Usage

Suitable for large-area underground mining area backfill, mine land reclamation and tunnel basic filling projects.
