OMC Industrial water : Avg. 69 m3/day (peak 148 m3/day) Jalpa Nala Man Power The mine shall employ 599 persons. All the unskilled workers, most of the semiskilled workers and a significant number of skilled workers will be local villagers or from nearby towns. Out of total manpower, about 401 shall be through contracting. Electricity At present 1100 KW power is drawn from 33 kV line from Joda Demand substation of Grid Corporation of India. Additional power shall be drawn from the same source, if required. Infrastructure Since the mine was operational till April 2006 most of the infrastructure required for the project are already available in the mine such as office, magazine, roads, canteen, roads, township etc. In case need arises, construction will be done as per requirement.
