Tensa has been declared the best mine by the Director General of Mines Safety, Govt. of India
JSPL’s iron ore mines, at Tensa valley in district Sundargarh, Odisha, 100 km from Rourkela partially fulfill the company’s requirement of iron ore for producing sponge iron. Produced as part of JSPL’s backward integration plans to make the company self reliant, iron ore from Tensa mines ensures consistency in the quality of raw material used in sponge iron kilns. Operational since 1990, these mines are popularly known as TRB (Tantra, Raikela, Bandhal) Mines.
The mines at Tensa meet a part of the company’s iron ore requirement for the sponge iron plant. Equipped with fully mechanised techniques, it currently produces about 9,00,000 MT of sponge grade iron ore. An additional mobile screening unit has been installed to ensure the availability of high-grade iron ore / fines for its sinter plant at Raigarh (Chhattisgarh).
Mining is done by top slicing method. OB and Ore are removed mechanically with the help of excavator and dumper. Average heights of the benches are maintained as per the regulations and permissions granted by the Director of Mines Safety, Chaibasa region. The ROM is fed to the crusher to get the final product of 5 - 20 mm crushed ore.
Haul roads are maintained properly, taking into account width and gradient. Strong parapet walls all along the haul road have been provided & maintained.
Drilling operation is carried out at the mines with the help of XAH-210 Atlas Copco compressor and wagon drills. A water injection system has been provided in the wagon drill for wet drilling to suppress the fugitive dust. Rock breaker has been provided to break the oversize boulders eliminating secondary blasting.
Sufficient water spraying arrangements have been provided to suppress dust on haul roads with the help of 2 Nos. 10 KL & 1 No. 12 KL capacity water tankers throughout the working shifts. Water sprinkling has also been provided at all discharge points of OPP (Ore Processing Plant) along with the atomized sprinkling arrangement.
35 MT capacity dumpers transport the ROM from mine to crusher through a well-maintained haul road. The haul road is one of the best in the locality, for which we have been accorded the best haul road prize during the Annual Mines Safety Week Celebration every year.
Set amidst a picturesque view with greenery all-around, these mines also house JSPL’s valuable team of workers. They are provided accommodation facilities with essential and recreational amenities like dispensary, playground, children’s parks, clubs, sports facility, co-operative society, conveyance to attend duty, etc.
