AMCMRR - AN ANALYTICAL MODEL FOR COAL MINE ROOF REINFORCEMENT

摘要: An analytical model for coal mine roof reinforcement (AMCMRR) has been developed. AMCMRR utilises a Factor of Safety (FOS) approach which is commonly used in all forms engineering. The starting point the development was an existing behaviour and support design methodology/model originally developed by second author. This technique being successfully utilised Australian underground industry evaluation prior to during course ALTS 2006 research project when essentially calibrated on site basis. It long recognised that bolts longer tendons can modify behavior load bearing capacity reinforced via concept beam building. break-through combining original with database effectively quantify this reinforcing effect turn provides "platform" be entire industry. two techniques (analytical-AMCMRR empirical-ALTS 2009) now work together as part overall more robust support/longwall gateroad methodology. paper focuses application use analyses undertaken offered immediate
