Determining integral permeability of undermined coal rock mass in closed mines
Effect of mining on pressure variation in coal rock mass has been analyzed. Methods to determine integral permeability as well as fluid pressure variations within undermined coal rock mass have been proposed. A technique to identify zones of “fast” gas and “slow” gas within undermined formation has...

| Summary: | Effect of mining on pressure variation in coal rock mass has been analyzed. Methods to determine integral permeability as well as fluid pressure variations within undermined coal rock mass have been proposed. A technique to identify zones of “fast” gas and “slow” gas within undermined formation has been considered. |
