Productivity is often illdefined as more output for fixed input or the same output for less input In our opinion productivity gain should be measured as a form of optimization ie the highest ratio of output to input which could in fact mean achieving higher productivity with lower input Over the broad spectrum of different mining
Moreover the effect of largescale mining coal with the production volume exceeds 12 million tons per year with the operation time more than 20 years on land subsidence was found greater than
The biggest difference between water resource utilization and management in coal mining area and other region is that the supply of water resources for coal mining area is severely affected by
For example there is the use of hispeed resin bonding customised roof bolts in the Australian coal mining industry and sensor based technology that reduces the need for human input for example sorting machinery uses this tool to separate valuable mineral ores from waste rock significantly reducing the time taken to do this manually
