主 题：similarity simulation advance rate working face with great mining height ground pressure
摘 要：Presently most of research results on strata behaviors were concluded under the normal （moderate） advance rate conditions. Comparing with normal advance rate, fast advance rate and slow advance rate may cause some new changes of strata behaviors. The characteristics of ground pressure behaviors in working face with great mining height at different forward speeds were studied by similarity model experiment in laboratory. Its conclusion provides a theoretic basis for ground pressure controlling.
