【Abstract】 The optimization principle and method of stope size of sublevel caving method for thick orebody mining is put forward, and the main factors of influencing stope size are analysed.The mathematical relation of mining stope size to ore removal parameters of scraper and the cost of ore production is analyzed respectively,and an approach of optimizing stope size in sublevel caving is founded. The reasonable size of sublevel caving stope is calculated for Beiminghe Iron Mine according to the actual production data.更多还原
