During the next seven years, a further four electrically driven rope haulages were installed, freeing up 44 horses and raising output to 1700 tons per day.

Depillaring with stowing is going on. The 7&8 pit unit was also working Sonachora seam (R-VIIIB) by semi-mechanized bord and pillar method with SDL. Only development work was going on. Coal from the underground coal face was hauled by a combination of haulages to feed the winding system through which coal tubs were raised up to the surface. 11\.

Depillaring (splitting as final operation) was being done with stowing. Coal from the underground coal face was hauled by a combination of haulages to feed the winding system through which coal tubs were raised to the surface. 10\. Nabakajora UG mine, with Madabpur UG mine (at sr. no. 11 below) has a combined peak annual capacity of 0.30 mt, is expected to have life of over 25 years.

Development in Dobrana (R-V) seam was nearly complete and some of the panels had been depillared with stowing. Loaded tubs were transported below ground by a combination of tugger and endless haulages to feed the installed winding system for final transport to the surface. An OC patch was under operation within the limits of the colliery. At Belbaid colliery, reserves of Dobrana (R-V) seam were expected to last another 7 to 8 years.

South Bruny was opened up by numerous tramways and haulages, some horse-drawn and some using modified locomotives. The longest and best preserved tramway runs from Adventure Bay to the far southeast corner of the island. Almost all settlements on South Bruny were originally opened as timber ports owned by the different timber companies operating on the island. Lunawanna (former Daniels Bay), Alonnah (former Mills Reef) and Adventure Bay were some of the largest ports operating on the island.

Parascole East & Parascole West UG mine, with peak annual capacity of 0.39 mt, is expected to have a life of over 25 years. As of 2015–16, the mine was working Jambad seam (R-VIII) by the bord and pillar method with stowing, manually in the top section and by SDL in the bottom section. Coal from the underground coal face is hauled by a combination of haulages to feed the winding system through which coal tubs are raised up to the surface.

In A&B; pit unit, depillaring with stowing was being done. In C pit unit, development was being done with SDLs. Coal from the underground coal face was hauled by combination of endless and tugger haulages to feed the winding system through which coal tubs were raised up to the surface. 6\. Parasea UG mine & OC patch, consisting of Parasea UG mine and OC patch, with a combined peak annual capacity of 0.61 mt, is expected to have a life of over 25 years.

Loaded tubs are transported below ground by combination of tugger and endless haulages to feed the winding system installed at pits of Kunustoria UG unit for final transport to the surface. 3\. Amrasota UG mine, with peak annual capacity of 0.15 mt, is expected to have life of more than 25 years. In Amrasota Incline, Kunustoria seam was being worked under development phase where coal was loaded into tubs by SDLs. Subsequent to completion of development phase, it was envisaged to depillar the seam in conjunction with hydraulic sand stowing.

Coal from the underground coal face was hauled by a combination of endless and tugger haulages to feed the winding system through which coal tubs were raised up to the surface. It had also been envisaged to exploit virgin Dobrana seam (R-V ) by deepening No.2 pit up to Dobrana seam, sinking a staple pit from Kenda seam to Dobrana seam and driving one drift from Kenda seam to Dobrana seam. 7\. Parasea 6 & 7 UG mine, with a combined peak annual capacity of 0.06 mt, was expected to have a life of over 25 years. As of 2015–16, there was no production from the UG mine. 8\. Jambad OC mine, with a peak annual capacity of 0.80 mt, is expected to have a life of over 25 years.

Coal from the underground coal face is hauled by a combination of haulages to feed the winding system through which coal tubs are raised up to the surface. 14\. Khas Kajora UG mine, with peak annual capacity of 0.35 mt, is expected to have a life of over 25 years. In 2015–16, Khas Kajora UG mine was working on depillaring with sand stowing in R-VIII (T), R-VIII (B) & R-VI seams. The Chora (R-VI) seam was being worked by manual bord and pillar method with depillaring and stowing. The mine is a degree-II gassy mine. 15\. Moira UG mine, with an annual capacity of 0.06 mt, is expected to have life of over 25 years. In 2015–16, Moira UG mine was developing Jambad seam (R-VIII) by the bord and pillar method with loading by SDLs. 16\. Madhusudanpur UG mine, with peak annual capacity of 0.24 mt, is expected to have life of over 25 years.
