Study on Filling Mining Technology of Sanshandao Gold Deposit
Filling method is adopted to control the ground pressure of underground stope of Sanshandao gold deposit at present, mechanized largescale trackless equipments is combined, takes the leading role in China. Cement and classified tailings are the main binder backfill material of Sanshandao gold deposit, cement sand ratio generally show 1：8 - 1： 16, backfill concentration is around 65% , how to ensure miningfilling balance is the important issue facing at present. Meanwhile, reducing the cement proportion of backfill and improving the backfill strength are the main direction in future study.
