titleOfInvention | Process for preparing and gasifying a coal seam at great depth |
abstract | In preparation for mining, a network of tunnels is conventionally driven into the rock below the level of a layer to be exploited. A weir with a minimum thickness of forty to fifty meters is now released between these tunnels and the layers to be exploited. Throughout the gasification process, the only connections between the adit and the strata under mining are a number of small diameter wells drilled prior to commencement of mining and lined with pipes cemented into the rock. |
