29. The following steps have been taken after GDK.7 LEP inundation disaster to avoid such type of accidents. 1. Audit teams have inspected the mines and submitted the deviations in respect of inundation and fires. Regular feed back is being obtained for rectification's of the deviations. 2. Chief Surveyor thoroughly scrutinised the plans. 3. Technical guidelines were issued regarding stowing districts vis- à -vis inundation. 4. CGM(Safety) had taken up safety awareness programmes at all the areas on GDK.7 LEP disaster. Steps taken after 7LEP Accident
