Paper Title:
Mining Research of Coal Replaced with Gangue in Folded Fault Area
  Abstract

Aiming at problem of low coal mining rate and environmental pollution by gangue, replacement mining technology of source recovery by excavating large span roadway and backfilling with gangue is put forward in this paper. Then combined control technology of roof cable truss and coalside cable-channel steel is applied to support the large span roadway, its control mechanism is discussed and the combined support scheme is defined by way of numerical simulation. Besides, according to the practice production condition, the replacement system which consists of gangue pretreatment, transport and replacement is established, achieving harmonic extraction of resource recovery and environmental protection and providing scientific basis and technological means for resource recovery under other geological conditions.
