- Abstract
As an important component of green mining techniques, backfill mining has experienced great development in China coal mines in recent 10 years. The purpose of this paper is to present the state of the art of backfill mining in China coal mines. It begins with brief review on the developing history of backfill coal mining in China. Different types of backfill mining technology are presented in detail, including paste backfill mining, waste rock backfill mining, high water material backfill mining and partial backfill mining. Finally, problems existing in the backfill mining, embracing insufficient insight into subsidence control effect, low productivity with backfill, high capital cost and lack of backfill, are discussed. Partial backfill mining may be an alternative to address the problems.
