Table 2.

Comprehensive evaluation and comparison table for technical-economic, safety-efficacy, and engineering adaptability of mining methods.

Mining methods	Production capacity/(t/d)	Recovery rate/%	Dilution rate/%	Cutting ratio/(m/kt)	Strata control effectiveness	Difficulty of implementation
Upward horizontal layered filling method	200–300	88–92	5–8	8–15	Effective	Easy
Shrinkage stoping with delayed backfill	100–150	85–90	10–15	4–7	Satisfactory	Moderate
Sublevel Stoping with delayed backfill	500–600	80–85	15–20	5–7	Marginal	Difficult
